Abstract
PURPOSE To investigate whether polymorphisms of GAS6 and PROS1, which each encode protein ligands for a family of tyrosine kinase receptors, are associated with Behçet's disease (BD) in a Japanese population. METHODS We recruited 734 Japanese patients with BD and 1789 Japanese healthy controls. In all participants, we genotyped two single-nucleotide polymorphisms (SNPs) reportedly associated with BD: rs9577873 in GAS6 and rs4857037 in PROS1. RESULTS We found that GAS6 rs9577873 was not significantly associated with BD. In contrast, PROS1 rs4857037, specifically the A allele, was associated with increased risk for BD. The A allele was also significantly associated with BD under additive and recessive genetic models. Expression analysis revealed that this allele was significantly associated with increased PROS1 expression. CONCLUSIONS Our findings suggest that increased PROS1 expression related to the A risk allele of rs4857037 affects tyrosine kinase receptor signaling, contributing to the development of BD.

Abstract
INTRODUCTION Drowning is a comprehensive and exclusive diagnosis at autopsy. Autopsy findings such as pleural effusion and waterlogged lungs contribute to the diagnosis. Herein, we aim to reveal the practical usefulness and postmortem changes of the maxillary sinus fluid volume to diagnose drowning. METHODS We evaluated 52 drowning and 59 nondrowning cases. The maxillary sinus fluid volume was measured using a computed tomography (CT) scan, and pleural effusion volume and lung weight were manually measured at autopsy. The utility of these three indices for diagnosing drowning and its postmortem changes was evaluated. RESULTS The maxillary sinus fluid volume was significantly higher in drowning cases than in other external causes and cardiovascular death cases. Receiver operating characteristic curve analysis revealed that a total maxillary sinus fluid volume >1.04 mL more usefully indicated drowning (odds ratio, 8.19) than a total pleural effusion volume >175 mL (odds ratio, 7.23) and a total lung weight >829 g (odds ratio, 2.29). The combination of maxillary sinus fluid volume and pleural effusion volume more effectively predicted drowning than one index alone. Moreover, the maxillary sinus fluid volume was less influenced by the postmortem interval than the other two indices up to a week after death. CONCLUSION Maxillary sinus fluid volume can be more useful than pleural effusion volume and lung weight with higher sensitivity and odds ratio for diagnosing drowning. IMPLICATIONS FOR PRACTICE Fluid accumulation in both the maxillary sinuses strongly predicts drowning in the postmortem imaging.

Abstract
Abstract
Background
Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC) is inherited cardiac disease with unresolved treatment. ARVC is progressive and leads to lethal arrhythmias and terminal heart failure. Most often encountered ARVC mutations are in desmosomal genes [1].
Purpose
We aimed to generate transgenic mice with exact copy of genetic defects found in Japanese cohort of ARVC patients, describe the phenotype, and identify target for curative therapy.
Methods
CRISPR/Cas9 genome editing was used to generate knock-in mice with the two most common point mutations in Japanese ARVC patients: DSG2 292R>C and 494D>A [2] (mouse equivalent positions are 297R and 499D, respectively). To analyze the phenotype of mice we used imaging techniques - cardiac echography and MRI as well as telemetry, treadmill, immunohistochemistry, confocal microscopy, histology, Western blot.
Results
In vivo observations of transgenic mice demonstrated inequalities in phenotypical presentation between the two mutations. Some of 297C mice (both hetero- and homozygous) died suddenly, starting from the age of 9 weeks, in contrast to surviving all 499A carriers. Dissection of suddenly died mice reveals enlarged cardiac cavities, mainly in the right heart. In addition, 297C homozygous hearts present with pale zones scattered all over the heart. Paraffin sections from this hearts stained with hematoxilin/eosin and Masson's trichrome show myocardial areas with absent myocytes, collagen accumulation and calcifications. With exception of homozygous 297C mice, spontaneous development of cardiac phenotype in Dsg2 knock-in mice starts after 25th weeks of age. Both mutant mice gradually developed cardiac dysfunction (echography and MRI, Fig. 1) and echographically visible left ventricular wall infiltrations. Heterozygous 297C mutation produces more severe phenotype that develops earlier. Similar to human ARVC, the degree of cardiac damage vary significantly. It is known from the human ARVC that physical activity aggravates the ARVC phenotype and may cause sudden cardiac death. To evaluate the effect of physical stress on the phenotype of Dsg2 knock-in mice we subjected 11 weeks old animals on treadmill exercise. Training for 8 weeks provoked development of heart failure in both 297C and 499A mutant mice, significantly earlier than natural progress of the phenotype. No mouse died suddenly. Telemetry experiment demonstrated electrical instability in 297C homozygous hearts showing conduction and rhythm abnormalities (Fig. 2). Apoptosis was detected in both mutant mice by TUNEL staining and confocal microscopy. Dsg2 protein expression was not affected by the mutations.
Conclusion
We generated mouse model of ARVC that reproduces exact genetic defect of the human disease. There are significant similarities between our model and ARVC patients' phenotype.

Abstract
Abstract
Background
Cardiac calmodulinopathy is a life-threatening arrhythmia syndrome which presents several phenotypes of inherited primary arrhythmia syndrome (IPAS), and caused by mutations in calmodulin-encoded genes (CALM1–3). We aimed clarify the frequency and their clinical characteristics of calmodulinopathy in our IPAS cohort.
Methods
By using next generation sequencing, we screened arrhythmia related genes including calmodulin-encoding genes in 322 unrelated symptomatic children (0–12 years) who were suspected as IPAS; they included 40 cases with lethal arrhythmic attacks (LAE) under 6-year-old. After gene screening, we investigated their physiological and clinical characteristics about mutation carriers.
Results
Among 322 children, we identified 6 mutations of calmodulin-encoded genes in 9 probands (2.8%); one CALM1 in 2 probands (N98S), and 5 CALM2 in 7 probands (E46K, D96V, D96G, N98S, E141K). Their clinical diagnoses were long QT syndrome (LQTS, n=4), catecholaminergic polymorphic ventricular tachycardia (CPVT, n=3) and both (n=2). Their age of diagnosis ranges at 0–9 with the median of 5 years. There were three major clinical phenotypes; 1) CALM2-D96V, and E141K: two infants with advanced atrio-ventricular block, significant QTc prolongation, severe heart failure from their fetal period – both of them deceased within 1.5-year-old. Their clinical phenotypes resembled classical Timothy syndrome caused by CACNA1C mutations. 2) CALM1-N98S (n=2), CALM2-N98S (n=2), and CALM2-D96G: four preschoolers with LAEs and one syncope: all of them were 3–5 years old. In addition, a T wave morphology of CALM2-D96G carrier was very similar to LQT1. 3) CALM2-E46K (n=2): two were first diagnosed with neurological and developmental disorders, and showed phenotype of CPVT: their cardiac phenotypes were milder compared with that of 1) or 2). Overall, these phenotypes seemed to be mutation specific (indicated in figure). Their cardiac features were severer, and the onset of LAEs was earlier compared with other genotypes of LQTS/CPVT. As the treatment, β-blocker was effective for control of LAEs.
Conclusion
Cardiac calmodulinopathy presented serious and potentially lethal phenotypes in fetus or infancy. To prevent cardiac death in them, we must correctly diagnose and start the treatment as earlier as possible.

Abstract
Abstract
Background
Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited cardiomyopathy mainly caused by desmosomal gene variants. In Europe and North America, pathogenic variants in PKP2 were identified in most of the ARVC patients. On the other hand, we have reported that the genetic backgrounds of ARVC in Japanese were different from those in European; pathogenic variants in DSG2 were predominant in Japanese. Genotype-phenotype correlations, however, have not been clarified yet.
Purpose
In this study, we aimed to examine whether the genotype affect the phenotype and outcome in Japanese ARVC patients.
Methods and results
This study included 167 Japanese ARVC patients who received genetic testing (128 males [77%]). Their median age at diagnosis was 44 [24–55] years old and median follow-up duration was 10 [4–21] years. We found 90 patients with pathogenic variants: 52 in DSG2 (31%), 30 in PKP2 (18%), 3 in DSP (1.8%), 1 in DSC (0.6%), 1 in JUP (0.6%) and 3 in DES (1.8%). The age of the first sustained ventricular arrhythmia (SVT) were older in the patients with DSG2 than those with PKP2 variants (48±15 years vs. 35±15 years, P=0.008) but younger in DSG2 variant carriers at the first hospitalization for heart failure (41 [22–61] years vs. 67 [61–74] years, P=0.03). The left ventricular ejection fractions of DSG2 variant carriers were significantly lower at diagnosis than that of PKP2 (52 [41–60] % vs. 61 [56–66] %, P=0.002). Kaplan-Meier survival curve for lethal arrhythmic events including SVT, ventricular fibrillation and sudden death revealed that the event rate of DSG2 variant carriers was significantly lower than that of PKP2 (log-rank test, P=0.02) (Fig. 1).
Among 11 patients who had both SVT and hospitalizations for HF, 7 PKP2 variant carriers had SVT first, then, hospitalized for HF (48 [35–53] years and 67 [55–71] years, P=0.02). Contrary, the clinical course of 4 DSG2 variants carriers were different from those with PKP2 (54 [40–68] years for SVT and 65 [56–70, P=0.1] years for HF) (Fig. 2).
Conclusion
The patients with DSG2, which is the major causative gene for ARVC in Japanese, show different phenotype and outcome from those with PKP2. We should examine the effect of variants on the prognosis of ARVC patients in more large population including various ethnics.

Abstract
PURPOSE To clarify the proportion of ocular sarcoidosis with severe, refractory, and prolonged inflammation and their association with ocular complications and visual prognosis. STUDY DESIGN Multicenter, retrospective, longitudinal cohort study. METHODS Three hundred and twenty-three eyes of 164 patients (45 men; 119 women) with ocular sarcoidosis who visited Hokkaido University Hospital and Yokohama City University Hospital from 2010 to 2015. We newly defined severe, refractory, and prolonged inflammation in ocular sarcoidosis, and investigated their proportions, ocular complications and final visual acuity from medical records of our sarcoidosis patients. RESULTS The eyes with severe inflammation numbered 72/323 (22.3%), with refractory inflammation, 80/323 (24.8%), and with prolonged inflammation, 91/323 (28.2%). The number of eyes having neither severe, refractory, nor prolonged inflammation (defined as none) was 114/323 (35.3%). The numbers of eyes that reached irreversible visual dysfunction were 6/72 (8.3%) of those with severe inflammation, 10/80 (12.5%) with refractory inflammation, 12/91 (13.2%) with prolonged inflammation, and 4/114 (6.2%) with none. As complications, cataract (62.2%), glaucoma (28.5%), epiretinal membrane (24.1%), cystoid macular edema (22.6%), vitreous hemorrhage (2.8%), choroidal atrophy (2.5%), macular degeneration (1.2%), macular hole (0.9%) and retinal detachment (0.3%) were identified. Among them, secondary glaucoma (16 eyes) and macular degeneration (4 eyes) were major complications related to irreversible visual dysfunction. CONCLUSIONS Although most of the patients with ocular sarcoidosis had a relatively good visual prognosis, some developed severe, refractory, and/or prolonged inflammation related to the development of ocular complications, that resulted in poor visual prognosis.

Abstract
Immune tolerance is established in the eye to prevent permanent blindness associated with destructive damage to the cornea and retina caused by immune cell infiltration; hence, the immune responses and subsequent inflammations are strongly suppressed. While non-infectious uveitis develops from a disruption of immune tolerance in the eye, its onset is a result of accumulating etiologic factors, including genetic predisposition, environmental factors, and aging. Many non-infectious uveitis cases are genetically predisposed to human leukocyte antigen (HLA) as the most substantial disease susceptibility region. HLA class I molecules are critical for natural killer (NK) cells to distinguish between self and non-self. The killer cell Ig-like receptor (KIR) family is one of the essential components of these receptors. Evidence has accumulated that NK cells are involved in innate and acquired immunity by interacting with other immunocompetent cells to develop several autoimmune diseases. This review summarizes the possible role of KIR in the development of non-infectious uveitis.

Abstract
PURPOSE To explore susceptibility loci associated with uveitis in Behcet's disease (BD). METHODS We conducted a genome-wide association study (GWAS) primarily involving 978 BD uveitis cases and 4388 controls and a replication study of 953 BD uveitis cases and 2129 controls in the Chinese population. Luciferase reporter analysis and Chromatin immunoprecipitation (ChIP) assay were performed to explore the functional role of susceptibility genetic variants nearby ZMIZ1. RESULTS Three independent HLA alleles (HLA-B51, HLA-A26 and HLA-C0704) were identified in a genome-wide association with BD uveitis. In the non-HLA region, besides confirming 7 previously reported loci, we identified 22 novel susceptibility variants located in 16 loci. Meta-analysis of the Chinese cohort involving 1931 cases and 6517 controls and a published Japanese cohort of 611 cases and 737 controls showed genome-wide significant associations with ZMIZ1, RPS6KA4, IL10RA, SIPA1-FIBP-FOSL1 and VAMP1. Functional experiments demonstrated that genetic variants of ZMIZ1 were associated with an enhanced transcriptional activity and an increased expression of ZMIZ1. CONCLUSIONS This GWAS study identified a novel set of genetic variants that are associated with susceptibility to uveitis in BD. These findings enriched our understanding of the contribution of genetic factors to the disease.

Abstract
Abstract
Background
Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited cardiomyopathy mainly caused by desmosomal gene variants. Although there are a lot of reports regarding to European ARVC patients, the ones in Asian are a few, and the characteristics of Asian ARVC have been still unclear. We have reported that the genetic backgrounds in Japanese ARVC patients were different from those in European ones. In this study, we aimed to examine the phenotype and outcome of Japanese ARVC patients with specific genetic backgrounds.
Methods and results
This study included 104 Japanese ARVC patients who were diagnosed as definite in the 2010 Task Force Criteria for ARVC and received genetic analysis (79 males [76%]; median age at diagnosis, 40 years [IQR 22–53 years].) Fifty-seven patients carried variants in desmosomal genes classified as pathogenic based on ACMG guideline: 30 in DSG2 (29%), 22 in PKP2 (21%), 2 in DSC2 (2%) and 3 in DSP (3%). The median age of diagnosis was significantly younger in the patients with the pathogenic variants than in those without (37 years [IQR 21–49 years] vs. 46 years [IQR 34–58 years], P=0.01). During a median follow-up of 9.3 years (IQR 3.5–20.9 years), 10 patients died and 2 were received heart transplantation. Sixty-two suffered lethal arrhythmic events including cardiopulmonary arrest, ventricular fibrillation, sustained ventricular tachycardia and appropriate shocks by implantable cardioverter defibrillator. Twenty-two were hospitalized for heart failure. There was no difference in these events rate between the two groups. However, survival analysis revealed that patients with pathogenic variants hospitalized for heart failure significantly earlier in their life than those without (P=0.04, log-rank test, Figure 1).
Conclusions
The Japanese ARVC patients with pathogenic variants in desmosomal genes are diagnosed and hospitalize for heart failure at younger age than those without. These findings have not been reported in other ethnics. Our study warns that we should be cautious for not only the prevention of lethal arrhythmic events but also the progress of the heart failure in Japanese ARVC patients with pathogenic variants.

Abstract
Behçet's disease (BD) is a chronic, relapsing inflammatory, multisystem disease of unknown etiology. The disease has a wide clinical spectrum of mucocutaneous lesions and ocular, vascular, articular, neurologic, gastrointestinal and cardiac involvement. Although the number of effective drugs used in the disease's treatment has increased in recent years, BD is still associated with severe morbidity because of mainly mucocutaneous, articular and ocular symptoms and an increased mortality because of large vessel, neurological, gastrointestinal and cardiac involvement. Many factors are associated with a more serious course, such as male gender and a younger age of onset. While the severity of the disease is more pronounced in the first years of the disease, it decreases in most patients after the age of forties. The primary goal of treatment should be the prevention of irreversible organ damage. Therefore, early diagnosis and appropriate treatment and close follow-up are mandatory to reduce the morbidity and mortality of the disease. Treatment varies depending on the organ involved and the severity of the involvement. For all these reasons, the treatment should be personalized and arranged with a multidisciplinary approach according to the organs involved. Treatment is mainly based on suppression of the inflammatory attacks of the disease using local and systemic immunomodulatory and immunosuppressive drugs. In this review, based on the mainly controlled studies and personal experience in clinical practice and basic research in this field, we propose a stepwise, symptom-based, algorithmic approach for the management of BD with a holistic perspective.

Abstract
Uveitis is a generic term for inflammation of the uvea, which includes the iris, ciliary body, and choroid. Prevalence of underlying non-infectious uveitis varies by race and region and is a major cause of legal blindness in developed countries. Although the etiology remains unclear, the involvement of both genetic and environmental factors is considered important for the onset of many forms of non-infectious uveitis. Major histocompatibility complex (MHC) genes, which play a major role in human immune response, have been reported to be strongly associated as genetic risk factors in several forms of non-infectious uveitis. Behçet’s disease, acute anterior uveitis (AAU), and chorioretinopathy are strongly correlated with MHC class I-specific alleles. Moreover, sarcoidosis and Vogt-Koyanagi-Harada (VKH) disease are associated with MHC class II-specific alleles. These correlations can help immunogenetically classify the immune pathway involved in each form of non-infectious uveitis. Genetic studies, including recent genome-wide association studies, have identified several susceptibility genes apart from those in the MHC region. These genetic findings help define the common or specific pathogenesis of ocular inflammatory diseases by comparing the susceptibility genes of each form of non-infectious uveitis. Interestingly, genome-wide association of the interleukin (IL)23R region has been identified in many of the major forms of non-infectious uveitis, such as Behçet’s disease, ocular sarcoidosis, VKH disease, and AAU. The interleukin-23 (IL-23) receptor, encoded by IL23R, is expressed on the cell surface of Th17 cells. IL-23 is involved in the homeostasis of Th17 cells and the production of IL-17, which is an inflammatory cytokine, indicating that a Th17 immune response is a common key in the pathogenesis of non-infectious uveitis. Based on the findings from the immunogenetics of non-infectious uveitis, a personalized treatment approach based on the patient’s genetic make-up is expected.

Abstract
Importance Although experimental studies support the hypothesis that exposure of infectious agents may trigger an aberrant immune response and contribute to noninfectious uveitis, the association of a definite pathogen with human noninfectious uveitis conditions appears not to have been well established in a population. Objective To evaluate associations of tuberculosis infection with risk of several noninfectious uveitis conditions. Design, Setting, and Participants These mendelian randomization and observational analyses were conducted with the genetic data of a Chinese cohort enrolled between April 2008 and January 2018 and a Japanese cohort enrolled between January 2002 and June 2009. We recruited participants for T-SPOT.TB (Oxford Immunotec) assays between July and November 2019. The Chinese cohort included patients with uveitis associated with Behçet disease or other uveitis conditions and control participants. The Japanese cohort and the group given T-SPOT.TB assays included individuals with Behçet disease and control participants. Data analyses for this study were completed from July 2019 to January 2020. Exposures Genetic variants associated with tuberculosis as natural proxies for tuberculosis exposure. Main Outcomes and Measures The primary outcome was the odds ratio (OR) for Behçet disease, estimated by an inverse variance weighted mean of associations with genetically determined tuberculosis susceptibility. The T-SPOT.TB positivity rate was examined in individuals with Behçet disease and compared with that of control participants. Results The Chinese cohort included 999 patients with uveitis associated with Behçet disease, 1585 with other uveitis conditions, and 4417 control participants. The Japanese cohort included 611 individuals with Behçet disease and 737 control participants. The group given T-SPOT.TB assays included 116 individuals with Behçet disease and 121 control participants. Of the Chinese individuals with Behçet disease and control participants, 2257 (41.7%) were female and the mean (SD) age was 35.4 (12.5) years. In the Japanese cohort, 564 (41.8%) were female and the mean (SD) age was 39.1 (12.7) years. Genetically determined tuberculosis susceptibility was associated with an increased risk for Behçet disease. The OR for Behçet disease per 2-fold increase in tuberculosis incidence was 1.26 (95% CI, 1.12-1.43; P = 1.47 × 10-4). Replication using the Japanese cohort yielded similar results (OR, 1.16 [95% CI, 1.08-1.26]). In T-SPOT.TB assays, having a positive result, indicating a history of tuberculosis infection, was found to be an independent risk factor for Behçet disease (OR, 2.26 [95% CI, 1.11-4.60]). Conclusions and Relevance These human genetic and biomarker data demonstrated that tuberculosis exposure was a risk factor for Behçet disease. This study provides novel evidence linking an infectious agent to the risk of a noninfectious uveitis condition.

Abstract
PURPOSE This study aimed to investigate the clinical features of intraocular inflammation (uveitis) in Hokkaido and to assess the etiology trends in comparison with those of our previous survey. METHODS We retrospectively reviewed the medical records of 1,616 new referral uveitis patients (1,020 females and 596 males) in Hokkaido University Hospital between 2004 and 2014. RESULTS Sarcoidosis was the most frequent etiology (17.4%), followed by Vogt-Koyanagi-Harada disease (8.1%), Behçet's disease (4.5%), and human leukocyte antigen B27 -associated uveitis (2.5%). The etiologies in 48.7% of the patients were unclassified. Compared to the previous survey between 1994 and 2003, the rate of Behçet's disease decreased and that of sarcoidosis increased. The rates of infectious uveitis and vitreoretinal lymphoma increased. CONCLUSION Although the order of the top four etiologies was the same in the two surveys, the rate of sarcoidosis increased and that of Behçet's disease decreased.

Abstract
Background
Calmodulin (CaM) is a ubiquitous Ca2+ sensor molecule encoded by three distinct calmodulin genes, CALM1–3, and has an important role for cardiac ion channel function. Recently, heterozygous missense mutations in CALM genes were reported to cause a new category of life-threatening genetic arrhythmias such as long-QT syndrome (LQTS) and catecholaminergic polymorphic ventricular tachycardia (CPVT), which is called as “calmodulinopathy”. The patients with calmodulinopathy show poor prognosis and there is no effective treatment for them.
Purpose
Considering the dominant-negative effect of mutant calmodulin proteins produced by heterozygous missense mutations in CALMs, we aimed to prove the concept of antisense-based therapy to treat calmodulinopathy using human iPS cell-derived cardiomyocyte (hiPSC-CM) model.
Methods
We designed multiple locked nucleic acid (LNA) gapmer-antisense oligonucleotides (ASOs) targeting CALM2 and analyzed the silencing efficiency and toxicity in cultured cells to select the most potent ASO. Using CMs differentiated from hiPSCs which were generated form a 12-year-old boy with LQTS carrying a heterozygous CALM2-N98S mutation, CALM2 expression and action potentials (APs) were analyzed to evaluate the efficacy of ASOs.
Results
We identified several ASOs which reduced CALM2 expression without affecting cell viability in human cultured cells (HepG2) (ASO 50 nM, n=2; Figure 1A). Considering further experiments in vivo mouse model, we investigated the CALM2 silencing activity in mouse cultured cells (3T3-L1) without transfection (free-uptake) (ASO 1 μM, n=2; †ASOs have homologous sequence between human and mouse; Figure B). After free-uptake CALM2 silencing analysis in 3T3-L1 cells, we identified that ASO #2 has the most potent CALM2 silencing activity and low cytotoxicity (Figure 1B). ASO #2 effectively reduced CALM2 expression even in hiPSC-CMs (ASO(−): n=3, lipofection: n=4, free-uptake: n=3; P<0.05; Figure 1C). In action potential recordings, we demonstrated that ASO #2 ameliorated prolonged AP durations (APD90) in N98S-hiPSC-CMs at 0.5 Hz pacing (ASO(−): 666±123 ms (n=7), lipofection: 329±21 ms (n=8), free-uptake: 388±34 ms (n=12); P<0.05; Figure 1D).
Conclusion
Our results using patient-derived hiPSC-CM model suggest that ASO-based therapy might be a promising strategy for the treatment of calmodulinopathy.

Abstract
Abstract
Introduction
Brugada syndrome (BrS) is an inherited arrhythmia characterized by a coved-type ST elevation and sudden death, especially in middle-aged males and more common in Asia. Mutations in SCN5A are detected in 15–20% and reported to be associated with poor prognosis. Among children, BrS is rare and the risk factors in pediatric BrS are unknown, especially in Asian population.
Purpose
The purpose of this study is to elucidate the risk factors for fatal arrhythmic events in Japanese pediatric patients with BrS.
Methods
We enrolled 52 Japanese children with BrS younger than 20 years, and performed genetic analysis and collected the clinical information.
Results
The mean age of initial symptoms was 10.7±5.5 years, and the mean follow-up period was 3.9±5.5 years. Ninety percent of patients were probands. No subjective symptom was confirmed in 28 of the patients, but aborted cardiac arrest (ACA) in 4, ventricular tachycardia in 4, ventricular fibrillation in 1, and syncope in 11. We identified mutations in SCN5A in 63%. There was no significant gender difference in ≤10 years, but a significant male predominance appeared in >10 years. And no gender difference was confirmed in the incidence of severe cardiac events in ≤10 years.
Conclusion
No gender difference was confirmed in ≤10 years in this study about Asian children. And being girls did not reduce the risk in ≤10 years. The frequency of SCN5A mutations was higher than adults, but decreased from childhood (68%) to adolescence (59%). In BrS, genetical and environmental factors may be more effective in childhood and adulthood, respectively.

Abstract
Abstract
Background
Genome structural variants (SVs) have larger effect on human genome functions than single nucleotide variants (SNVs). Although short-read sequencing (SRS) is current major next generation sequencing method and has given us a great benefit to elucidate the genetic background of inherited diseases, it does not detect SVs accurately. Long-read sequencing (LRS) produces tens to thousands of kilobases reads and detects the breakpoints of complex SVs. This study aimed to confirm a large deletion, which was suspected by SRS, using LRS by Oxford Nanopore technology (ONT).
Methods
Genomic libraries for SRS was prepared with HaloPlex. Targeted SRS was performed for 58 genes with MiSeq. Genomic libraries for LRS were prepared using the Ligation sequencing 1D kit SQK-LSK109 (ONT). Whole genome LRS was performed with GridION X5 and R9.4 flow cells (ONT).
Results
The patient was a five-month-old boy with atrial septal defect (ASD) and atrial tachycardia. Though SRS failed to identify any causative SNVs, the results with SureCall software (Agilent) suspected a deletion between exon 3 to exon 26 in MYH6 encoding α heavy chains of cardiac myosin. The variants in MYH6 are known to be associated with ASD. Because a deletion between MYH6 exon 26 and MYH7 exon 27 was reported as esv2748480 on the Database of Genomic Variants, we performed long-range PCR from MYH6 intron26 to MYH7 exon26 and found an abnormal 1.5K bases PCR product only in the case. Due to high homology of MYH6 and MYH7, Sanger sequencing failed to detect the break point.
In LRS, 3 flow cells generated 3.8M base-called reads containing 42G bases with N50 of 13K bases. We used NGMLR, which is a long-read mapper, to align the reads to the human reference genome (hg38). SVs were called by Sniffles detecting all types of SVs. The deletion was found to range from chr14: 23390037 to 23419824 (see figure) and did not contain other SVs. There was no pathogenic SV on ACTC1, GATA4, TBX20 and TLL1 which are genes related to ASD on Genetic Testing Registry.
His mother had also ASD and harbored the same deletion.
Conclusions
This is the first report to identify a large deletion between MYH6 and MYH7 in the family with ASD. The combination of SRS and LRS is useful to detect SVs in patients with suspected inherited diseases but carried no causative SNVs.

Abstract
Abstract
Background
Mutation/variant-site specific risk stratification in long-QT syndrome type 1 (LQT1) has been well investigated, but it is still challenging to adopt current enormous genomic information to clinical aspects caused by each mutation/variant. We assessed a novel variant-specific risk stratification in LQT1 patients.
Methods
We classified a pathogenicity of 142 KCNQ1 variants among 927 LQT1 patients (536 probands and 391 family members) based on the American College of Medical Genetics and Genomics (ACMG) and Association for Molecular Pathology (AMP) guidelines and evaluated whether the ACMG/AMP-based classification was associated with arrhythmic risk in LQT1 patients.
Results
Among 142 KCNQ1 variants, 60 (42.3%), 58 (40.8%), and 24 (16.9%) variants were classified into pathogenic (P), likely pathogenic (LP), and variant of unknown significance (VUS), respectively. The ACMG/AMP guideline-based classification was significantly associated with syncopal events (particularly those during exercise) and LQT risk score (Schwartz score) in overall population. On the other hand, arrhythmic risk was completely different between probands and families even in the same variants. The baseline QTc interval and variant location could stratify the risk in family members but not in probands, however, the ACMG/AMP-based KCNQ1 variant classification stratified the risk in LQT1 probands as well as family members. Multivariate analysis showed that proband (HR=2.52; 95% CI: 1.93–3.30; p<0.0001), longer QTc interval (≥500ms) (HR=1.41; 95% CI: 1.11–1.79; p<0.0001), variants at membrane spanning (MS) (vs. those at N/C terminus) (HR=1.40; 95% CI: 1.07–1.85; p=0.02), C-loop (vs. N/C terminus) (HR=1.58; 95% CI: 1.11–2.24; p=0.01), and P variants [(vs. LP) (HR=1.71; 95% CI: 1.33–2.23; p<0.0001), (vs. VUS) (HR=1.96; 95% CI: 1.19–3.46; p=0.007)] were significantly associated with syncopal events. A clinical score (0–4) based on the proband, QTc (≥500ms), variant location (MS or C-loop) and P variant by the ACMG/AMP guidelines allowed identification of patients more likely to have arrhythmic events (Figure A and B).
Conclusion
Comprehensive evaluation of clinical findings and pathogenicity of KCNQ1 variants based on the ACMG/AMP-based evaluation may stratify arrhythmic risk of congenital long-QT syndrome type 1.

Abstract
Abstract
Objective
LMNA is a known causative gene of dilated cardiomyopathy (DCM) and familial cardiac conduction disturbance (CCD). Genetic variants affecting the pre-mRNA splicing process often lead to premature stop codons and result in nonsense-mediated mRNA decay (NMD), followed by degradation of mutated alleles. The misssense variant LMNA c. 936G>C was previously reported in a French family affected by muscular dystrophy, CCD, and DCM, but no detailed analysis has been performed. We so far identified the same variant in two Japanese families affected by CCD and DCM. In this study, we investigated the molecular consequences of the variant located at the last codon of LMNA exon5 to demonstrate its pathogenicity.
Methods
Genomic DNA and total RNA were isolated from patients' peripheral blood lymphocytes or cardiac tissue. LMNA-coding exons were screened by direct sequencing. Complementary DNAs (cDNAs) were generated by reverse transcription PCR from RNA. Quantitative PCR (qPCR) was performed to quantify the LMNA cDNA amount by using specific primers for lamins A and C. The protein expressions of both isoforms were analyzed by western blotting.
Results
We detected the heterozygous LMNA c.936 G>C (p. Q312H) variant at the end of exon 5 by genomic DNA sequencing in two unrelated Japanese families (figure. pedigree) affected by DCM and CCD. In a genomic database survey, we did not find the variant in either gnomAD, TogoVar, or the Human Genetic Variation Database. The two commonly used splice site predictor tools, NetGene2 and FSPLICE, estimated that this site was a splice donor site. Sequencing of cDNA demonstrated that the mutated allele was absent. By qPCR assay, we confirmed a 90% reduction in LMNA cDNA. Western blot analysis revealed that lamin A and C expression was reduced far more than 50% (figure. western blot).
Conclusions
We report a LMNA missense mutation found in two families, which disrupts a normal splicing site, leads to NMD, and resulted in severe cardiac laminopathy. The drastic reductions of lamin expression at the cDNA and protein levels suggested that other co-existing mechanisms may also have suppressed the expression of the healthy wild type allele.

Abstract
Abstract
Background
A missense mutation, CACNA1C-E1115K, located in the cardiac L-type calcium channel (LTCC), was recently reported to be associated with diverse arrhythmias. Several studies reported in-vivo and in-vitro modeling of this mutation, but actual mechanism and target drug of this disease has not been clarified due to its complex ion-mechanisms.
Objective
To reveal the mechanism of this diverse arrhythmogenic phenotype using combination of in-vitro and in-silico model.
Methods and results
Cell-Engineering Phase: We generated human induced pluripotent stem cell (hiPSC) from a patient carrying heterozygous CACNA1C-E1115K and differentiated into cardiomyocytes. Spontaneous APs were recorded from spontaneously beating single cardiomyocytes by using the perforated patch-clamp technique.
Mathematical-Modeling Phase: We newly developed ICaL-mutation mathematical model, fitted into experimental data, including its impaired ion selectivity. Furthermore, we installed this mathematical model into hiPSC-CM simulation model.
Collaboration Phase: Mutant in-silico model showed APD prolongation and frequent early afterdepolarization (EAD), which are same as in-vitro model. In-silico model revealed this EAD was mostly related to robust late-mode of sodium current occurred by Na+ overload and suggested that mexiletine is capable of reducing arrhythmia. Afterward, we applicated mexiletine onto hiPSC-CMs mutant model and found mexiletine suppress EADs.
Conclusions
Precise in-silico disease model can elucidate complicated ion currents and contribute predicting result of drug-testing.

Abstract
OBJECTIVES Behçet's disease (BD) is characterised by repeated acute inflammatory attacks with aphthous ulcers of the oral mucosa, uveitis of the eyes, skin symptoms, and genital ulcers. Although its aetiology is still unknown, there is evidence of the involvement of oral bacteria in systemic diseases. Various types of oral bacteria may be involved in the development and progression of BD. The present study investigated alterations in the oral flora of patients with BD in Mongolia. We collected saliva samples from the Mongolian BD group and healthy control (HC) group, and the oral flora were analysed using next-generation sequencer (NGS). METHODS DNA was extracted from the unstimulated saliva samples from the 47 BD and 48 HC subjects. The DNA was amplified from the V3-V4 region of 16S rRNA using PCR, and the data were acquired using NGS. Based on the obtained data, we analysed the alpha diversity, beta diversity, and bacterial taxonomy of the salivary flora. RESULTS Beta diversity differed significantly between the BD and HC flora, but no significant differences were observed in alpha diversity. We found that the proportions of three genera - an S24-7 family unknown species, a mitochondria family unknown species, and Akkermansia species associated with IL-10 production - were significantly lower in the BD than in the HC group. CONCLUSIONS The reduced proportions of the S24-7 family and symbiotic Akkermansia species may be key phenomena in the oral flora of patients with BD.

Abstract
Sarcoidosis is a genetically complex systemic inflammatory disease that affects multiple organs. We present a GWAS of a Japanese cohort (700 sarcoidosis cases and 886 controls) with replication in independent samples from Japan (931 cases and 1,042 controls) and the Czech Republic (265 cases and 264 controls). We identified three loci outside the HLA complex, CCL24, STYXL1-SRRM3, and C1orf141-IL23R, which showed genome-wide significant associations (P < 5.0 × 10−8) with sarcoidosis; CCL24 and STYXL1-SRRM3 were novel. The disease-risk alleles in CCL24 and IL23R were associated with reduced CCL24 and IL23R expression, respectively. The disease-risk allele in STYXL1-SRRM3 was associated with elevated POR expression. These results suggest that genetic control of CCL24, POR, and IL23R expression contribute to the pathogenesis of sarcoidosis. We speculate that the CCL24 risk allele might be involved in a polarized Th1 response in sarcoidosis, and that POR and IL23R risk alleles may lead to diminished host defense against sarcoidosis pathogens. Akira Meguro et al. report a genome-wide association study for sarcoidosis—a systemic inflammatory disease—in the Japanese population. They identify 3 non-HLA loci with genome-wide significance, 2 of which have not been previously associated with sarcoidosis in any population.

Abstract
The definition, classification, pathogenesis, test methods, clinical findings, criteria for diagnosis, and therapies of allergic conjunctival disease are summarized based on the Guidelines for Clinical Management of Allergic Conjunctival Disease 2019. Allergic conjunctival disease is defined as "a conjunctival inflammatory disease associated with a Type I allergy accompanied by some subjective or objective symptoms." Allergic conjunctival disease is classified into allergic conjunctivitis, atopic keratoconjunctivitis, vernal keratoconjunctivitis, and giant papillary conjunctivitis. Representative subjective symptoms include ocular itching, hyperemia, and lacrimation, whereas objective symptoms include conjunctival hyperemia, swelling, folliculosis, and papillae. Patients with vernal keratoconjunctivitis, which is characterized by conjunctival proliferative changes called giant papilla accompanied by varying extents of corneal lesion, such as corneal erosion and shield ulcer, complain of foreign body sensation, ocular pain, and photophobia. In the diagnosis of allergic conjunctival diseases, it is required that type I allergic diathesis is present, along with subjective and objective symptoms accompanying allergic inflammation. The diagnosis is ensured by proving a type I allergic reaction in the conjunctiva. Given that the first-line drug for the treatment of allergic conjunctival disease is an antiallergic eye drop, a steroid eye drop will be selected in accordance with the severity. In the treatment of vernal keratoconjunctivitis, an immunosuppressive eye drop will be concomitantly used with the abovementioned drugs.

Abstract
Vogt-Koyanagi-Harada (VKH) disease is a systemic inflammatory disorder that affects pigment cell-containing organs such as the eye (e.g., chronic and/or recurrent granulomatous panuveitis). While the exact etiology and pathogenic mechanism of VKH disease are unclear, HLA-DR4 alleles have been documented to be strongly associated with VKH disease in various ethnic groups. Recently, a genome-wide association study (GWAS) found two new genetic risk factors (IL23R-C1orf141 and ADO-ZNF365-EGR2) in a non-HLA region from a Han Chinese population. In this study, we replicated these GWAS findings in a Japanese population. A total of 1,643 Japanese samples (380 cases with VKH disease and 1,263 healthy controls) were recruited. We assessed four single nucleotide polymorphisms (SNPs) shown in previous GWAS: rs78377598 and rs117633859 in IL23R-C1orf141, and rs442309 and rs224058 in ADO-ZNF365-EGR2. A significant allelic association with VKH disease was observed for all of the four SNPs (rs78377598: pc = 0.0057; rs117633859: pc = 0.0017; rs442309: pc = 0.021; rs224058: pc = 0.035). In genotypic association analysis, the minor alleles of IL23R-C1orf141 rs78377598 and rs117633859 had the strongest association with disease susceptibility under the additive model (pc = 0.0075 and pc = 0.0026, respectively). The minor alleles of ADO-ZNF365-EGR2 rs442309 and rs224058 were most strongly associated with disease susceptibility under the dominant model (pc = 0.00099 and pc = 0.0023, respectively). The meta-analysis of the current and previous studies found that all of the four SNPs exhibited a significantly strong association with VKH disease (meta-p < 0.00001: rs78377598, meta-odds ratio (OR) = 1.69; rs1176338, meta-OR = 1.82; rs442309, meta-OR = 1.34; rs224058, meta-OR = 1.33). In summary, our study replicated significant associations with VKH disease susceptibility reported in a previous GWAS. Thus, the IL23R-C1orf141 and ADO-ZNF365-EGR2 loci may play important roles in the development of VKH disease through genetic polymorphisms.

Abstract
PURPOSE To evaluate the efficacy and safety of intravitreal sirolimus in the management of noninfectious uveitis of the posterior segment (NIU-PS). DESIGN Combined analysis of 2 phase 3, randomized, double-masked, multinational, 6-month studies. PARTICIPANTS Adults with active NIU-PS (intermediate uveitis, posterior uveitis, or panuveitis; defined as vitreous haze [VH] ≥1.5+ on modified Standardization of Uveitis Nomenclature scale). METHODS Patients were randomized 1:1:1 to receive intravitreal sirolimus 44 μg (n = 208), 440 μg (n = 208), or 880 μg (n = 177) on days 1, 60, and 120. Patients discontinued medications for NIU-PS except for systemic corticosteroids, which were tapered according to protocol. Enrollment in the 880-μg group was terminated after interim results found no significant difference in efficacy compared with the 440-μg dose. MAIN OUTCOME MEASURES The primary efficacy end point was the percentage of patients with VH of 0 at month 5 in the study eye without the use of rescue therapy. Secondary efficacy end points included VH of 0 or 0.5+, corticosteroid-tapering success, and changes in best-corrected visual acuity (BCVA). Safety measures included ocular and nonocular adverse events. RESULTS A total of 592 patients were randomized. Significantly higher proportions of patients treated with 440 μg compared with 44 μg intravitreal sirolimus achieved VH of 0 (21.2% vs. 13.5%; P = 0.038) and VH of 0 or 0.5+ (50.0% vs. 40.4%; P = 0.049) at month 5. Best-corrected visual acuity was stable (absolute change <5 ETDRS letters) or improved >5 letters in 80.1% and 80.2% of patients in the 440-μg and 44-μg groups, respectively. At month 5, corticosteroids were tapered successfully in 69.6% and 68.8% of patients in the 440-μg and 44-μg groups, and among these patients, VH of 0 or 0.5+ was achieved by 43.5% and 28.1% in the 440-μg and 44-μg groups. Both doses were generally well tolerated. Mean changes from baseline intraocular pressure (IOP) in the study eye at each analysis visit were minimal in all treatment groups. CONCLUSIONS Intravitreal sirolimus 440 μg improved ocular inflammation, as measured by VH, compared with the 44-μg dose, with minimal impact on IOP, while preserving BCVA.

Abstract
OBJECTIVE The aim of the present study is to investigate the clinical features of patients with Behcet's disease (BD) in Mongolia. METHODS Patients were identified and examined from six medical institutions in Mongolia from January 2015 to January 2019. BD was diagnosed according to the diagnostic criteria for BD established by the International Study Group. RESULTS There were sixty-five patients (22 males and 43 females) recoded, the ratio of 1:1.95, with a marked female predominance. The age of disease onset was 22.2 ± 10.0 (mean ± SD), ranging from 11 to 66 years old. Oral aphthous ulcers, ocular lesions, skin lesions, genital ulcers, pathergy test positivity, articular lesions, superficial vasculitis, deep vein thrombosis, and epididymitis (male only) were observed in 100.0%, 63.1%, 81.5%, 89.2%, 7.7%, 86.2%, 32.3%, 4.6%, and 13.6% of the patients, respectively. The incidence of poor visual prognosis, ≤ 20/200, was significantly higher in males than in females (31.8 vs. 9.3%, incidence rate ratio 4.55 (95% CI 1.16-17.82), p < 0.05). The pathergy test was positive only in 7.7% of cases and only in female subjects. Nasal mucous ulcers were frequently seen in 55.4% of patients that may also be attributed to the environmental conditions of Mongolia. Headache was observed 76.9% of patients in this study. CONCLUSIONS Clinical manifestations of BD in Mongolia are presented for the first time. The visual prognosis was significantly worse in males. Nasal mucous membrane ulcers and recurrent headaches were frequent among Mongolian patients with BD. Key Points • First results of the examination of the clinical features of Behcet's disease patients in Mongolia. • Nasal ulcerations and recurrent headaches are frequent symptoms in Mongolia Behcet's disease patients, potentially attributed to climate. • Male Behcet's disease patients in Mongolia have a significantly worse prognosis for eye-related complications and vision.

Abstract
PURPOSE The aim of this study was to test the antiviral effectivity of potassium peroxymonosulfate (RUBYSTA®, KYORIN) against five epidemic keratoconjunctivitis-related types of Human adenovirus D in vitro. METHODS Five types of Human adenovirus D (8, 37, 53, 54 and 56) were incubated with 1% potassium peroxymonosulfate, 0.1% sodium hypochlorite (NaClO) or alcohol-based disinfectant for 30 s or 1 min. These solutions were subjected to measurements of viral titres by infection assays in A549 cells. At day 6 post-infection, both, supernatants and cells, were collected and the viral genome was assessed by real-time polymerase chain reaction analysis. RESULTS Treatments with 1% potassium peroxymonosulfate led to significant reduction in all tested Human adenovirus D types comparable to disinfecting effects by 0.1% NaClO. Overall, potassium peroxymonosulfate demonstrated sufficient inactivation of the major epidemic keratoconjunctivitis-causing Human adenovirus D to be considered for disinfection and prevention purposes in ophthalmological clinics and hospitals. CONCLUSION This study demonstrated that potassium peroxymonosulfate is a promising disinfectant for the prevention of epidemic keratoconjunctivitis nosocomial infections in ophthalmological clinics.

Abstract
Abstract
Background
Long QT syndrome type 8 (LQT8) caused by mutations in CACNA1C has been classified as a very rare and severe type of long QT syndrome accompanied with Timothy syndrome (TS) with extra-cardiac phenotype. Recently, various mutations in CACNA1C have been identified in non-TS patients. However, mutation specific severity in LQT8 has not been elucidated yet, especially for non-TS patients.
Purpose
We aimed to clarify the clinical characteristics of LQT8 patients.
Methods
The study consists of 26 LQT8 patients (21 probands and 5 family members). We evaluated their phenotype.
Results
Table summarizes the clinical characteristics of LQT8 patients. TS patients diagnosed in younger age than those of non-TS. Four TS and one non-TS patients were diagnosed at the age of 0, though the non-TS patient was a son of a patient and asymptomatic. Nine patients suffered symptoms including 7 with cardiac arrest. We identified three TS mutations; classical p.G406R in two and p.G402S in two, and a new TS mutation, p.412M in one. Four of TS patients were symptomatic and two died suddenly at the age of 4 and 5. In contrast, no one died in non-TS patients. Five non-TS patients suffered symptoms in the age of 4,9,15,54 and 64, and the mutations were p.S643F, p.R858H (2 patients), p.K1518E and p.K1591T.
Characteristics of TS and non-TS patient TS Non-TS P N (male) 5 (2) 21 (9) Age (range) 0 (0–7) 12 (0–64) 0.004 Symptom Syncope 4 5 0.034 CPA 3 4 0.101 ECG characteristics QT interval 603±40 507±14 0.011 T wave alternans 5 2 <0.001 AV Block 4 1 0.002 Therapy (4 unknown) Beta-blocker 4 7 0.311 Mexiletine 3 1 0.024 ICD implantation 2 2 0.21
Conclusions
Although TS patients showed severe phenotype, most of the non-TS patients were asymptomatic. The phenotype in LQT8 are diversely different depend on the mutations, especially between patients with TS and non-TS.

Abstract
Abstract
Background
Early repolarization syndrome (ERS) is characterized by J-point elevation in the ECG and ventricular fibrillation (VF). Several mutations in genes encoding cardiac ion channels have been reported as the causes for ERS. For the treatment of ERS, clinical studies have shown that quinidine is effective for the suppression of electrical storm. However, the mechanism or the optimal concentration for quinidine to suppress the electrical storm has not been elucidated yet.
Purpose
The aim of the present study is to clarify pharmacological effect of quinidine on mutant Kv4.3 channel by electrophysiological analysis and to establish theoretically effective treatment for ERS.
Methods
A KCND3 mutation, p.G306A, identified heterozygously in a 12-year-old boy was examined by whole-cell patch-clamp methods using CHO cells. We performed functional analysis of the Kv4.3 channels encoded by KCND3 of wild-type (WT), heterozygous (WT/G306A), or homozygous (G306A) mutants. Pharmacological normalizing effects of quinidine to the WT and mutant channels were investigated by loading test in various concentration. The sensitivity of quinidine was evaluated in terms of the concentration of the clinical course and the loading test.
Results
The patient suffered VF while sleeping or under sedation. Significant J-point elevations in multiple leads were recorded and he was diagnosed as ERS. Quinidine administration in the serum concentration of 1.2 to 3.1 μM was effective to stop his VF storm. Mutant Kv4.3 currents showed significantly slow inactivation time course (Fig 1), which meant that the mutation caused the gain-of-function channel. Quinidine loading to the mutant Kv4.3 normalized the inactivation time course in concentration-dependent manner (Fig 2, 3). In the loading concentration of 1 μM, the peak currents were not changed regardless of the voltage (Fig 4). The optimal serum concentration of quinidine in clinical use as multi-ion-channels blocker is 6 to 15 μM and the concentration was higher than that of the patient to stop the VF storm. The electrophysiological analysis showed that the low dose loading of quinidine was effective to prevent the gain-of function change of mutant Kv4.3 channels.
Electrophysiological analysis
Conclusions
We showed the pharmacological mechanism of quinidine against the mutant Kv4.3 channels identified in an ERS patient. Even the low concentration of quinidine was effective to normalize the slow inactivation, gain-of-function, in mutant Kv4.3 channels. Our data would be helpful to confirm the optimal concentration of quinidine for ERS patients to avoid adverse effect.

Abstract
Abstract
Background
The cardiac ryanodine receptors (RyR2) are large tetrameric calcium-permeant ion channels found in cardiac muscle sarcoplasmic reticulum, which play an important role in the control of intracellular Ca2+ release and cardiac contraction. Mutations in the RYR2 gene are associated with lethal arrhythmia diseases including catecholaminergic polymorphic ventricular tachycardia (CPVT) resulting from increased diastolic Ca2+ leak from mutant channels. RyR2 is a huge protein that each subunit of tetramer is comprised of 4967 amino acids, which hampers the detailed in vitro analysis of RyR2 mutant channels.
Purpose
We aimed to analyze the structural features of RyR2 mutant channels identified in our cohort with inherited arrhythmias using RyR2 three-dimensional (3D) in silico model to reveal the arrhythmogenic mechanisms.
Methods
A targeted next-generation sequencing panel for inherited arrhythmias was employed for genetic diagnosis of the patients. Then, we mapped the identified mutations on RyR2 3D structural model developed by cryo-EM images (PDB: 5go9, 5goa, Peng Science 2016) and investigated the relationship between the location of the mutations and specific functional sites.
Results
As a result of genetic analysis, we identified 93 RYR2 mutations from 112 probands with CPVT (n=93) or long-QT syndrome (LQTS) (n=19).64 of 93 (69%) RYR2 mutations are located in three “hot-spot” area (N-terminal (residues 77–466), central (2246–2534), and channel (3778–4959) hotspot. RyR2 3D in silico modeling revealed that the mutations are regionally distributed mainly in three parts: N-terminal, periphery, and channel part (Figure A). In N-terminal part (1–642 amino acid), 9 of 13 mutations alter the charges of the amino acids (Figure B). Especially, R169L, R169Q, and G172E are close to the interface between two neighboring subunits (∼20Å). These mutations which change the amino acid charge may cause a complete disruption of the ionic pair network and result in largest structural changes, which facilitates RyR2 channel opening. In periphery part (643–3528aa), 22 of 33 mutations are close to the two predicted binding sites of FKBP12.6, a stabilizer of RyR2 (∼5–40Å, Figure C). The mutations are supposed to disturb the binding affinity to the FKBP12.6 resulting in RyR2 channel instability. In channel part (3613–4968aa), 16 of 40 mutations are located near two interface. (FigureD) 12 mutations are close to the Ca2+ sensor and the other 4 mutations are adjacent to the pore-forming segment. Especially, V4821I is just located on this segment and strongly expected to impair the channel function. Above all, RyR2 3D in silico modeling revealed that 63 of all 93 (68%) identified mutations are supposed to be pathogenic.
Location of RYR2 mutations in 3D model
Conclusion
3D structural model of RyR2 is useful for the investigation of the pathogenic mechanisms of CPVT-related mutations. Further studies are needed to elucidate the relationship between the location of the mutations and clinical phenotypes.

Abstract
Abstract
Introduction
Restrictive cardiomyopathy (RCM) is a rare myocardial disease with an impaired diastolic function and poor prognosis. The mean survival duration after a diagnosis of RCM is reported to be around 2 years in children and most need heart transplantations.
Purpose
This study aimed to determine the 12-lead electrocardiogram (ECG) diagnostic criteria of RCM based on the initial diagnostic electrocardiogram.
Methods
ECGs in pediatric cardiomyopathy patients were collected from 15 institutes in Japan between 1979 and 2013. We compared the ECG findings, especially of the P wave, in RCM patients between the cardiomyopathy group and healthy children group separately for each gender and the age. The ECGs in the healthy group were obtained from school heart screening in Japan of first-graders, and seventh-graders. Statistical significance was determined as p<0.001.
Results
Among 376 registered cardiomyopathy patients, 63 had hypertrophic cardiomyopathy (HCM) (36%), 91 (24%) dilated cardiomyopathy (DCM), 106 (28%) a left ventricular myocardial noncompaction (LVNCs), 25 (7%) restrictive cardiomyopathy (RCM), 14 (4%) arrhythmogenic right ventricular cardiomyopathy (ARVC), and 5 (1%) other cardiomyopathies. Of the 25 RCM patients (9.9±3.4 years old, F:M=11:14), 36% were discovered during school heart screening. The first onset was an abnormal ECG in 9, symptoms of heart failure in 6, respiratory tract infections in 3, syncope in 1, and 6 with other. Of those patients, 2 (8%) had a family history of RCM, 24 (92%) no family history. A genetic diagnosis was performed in 5 of the 25 cases, and 3 had genetic abnormalities related to RCM. The mean follow-up period was 65±95 months (mean±standard deviation). During follow up, 19 patients (76%) survived, 6 (24%) died, 7 (28%) had heart transplantations, and 3 (12%) were waiting for heart transplantations with a left ventricular assist device.
The P wave was bimodal in lead I or biphasic in lead V1 in 15 patients (93%), and 13 (81%) patients had both variations. We evaluated the duration and amplitude of the first and second component of the P wave as P1 and P2. The number of control and RCM patients (control/RCM), duration of P1+P2, and sum total absolute value of the amplitude of P1+P2 in lead V1 were 8350/5, 90±9/116±10ms, and 72±28/528±278μV in first grade boys, 8423/3, 91±10/120±22ms, and 66±28/326±229μV in first grade girls, 8943/1, 97±1/100ms, and 71±31/328μV in seventh grade boys, and 9183/5, 98±11/112±10ms, and 55±27/315±56μV in seventh grade girls. Although the number of patients in the RCM group was small, sum total absolute value of the amplitude of P1+P2 in lead V1 showed a significant difference in any group.
Conclusion
The ECG in children with RCM exhibits P wave abnormalities in almost all patients. In particular, not the P wave interval but P wave shape in I and V1 and the sum total absolute value of the amplitude of P1+P2 in lead V1 were observed differences.

Abstract
Adenoviral epidemic keratoconjunctivitis (EKC) is a major cause of ocular morbidity worldwide and specific antiviral therapies are not available. EKC is primarily caused by Human adenovirus D (HAdV-D) types 8, 37, 53, 54, 56 and 64. Considering the genomic variation in HAdV-D, we hypothesized that clinical signs could be differentiated by virus type. The hypothesis was retrospectively tested with clinical signs recorded from 250 patients with ocular infections visiting an ophthalmological clinic in southern Japan between 2011 and 2014. The results showed that conjunctival opacity, corneal epithelial disorders and pre-auricular lymphadenopathy, were more frequently associated with EKC than other ocular infections. Furthermore, HAdV types 8, 37 and 54, caused corneal complications and longer infections significantly more frequently than infections by types 53 and 56 (P < 0.05). Our descriptive results supported that symptoms severity vary with the infecting type, however, further research is needed to improve diagnosis of EKC.

Abstract
Purpose Relentless placoid chorioretinitis (RPC) is a new disease concept that was proposed by Jones et al. in 2000. Some cases of RPC have been reported; however, a treatment strategy has not yet been established. We report herein four cases of patients diagnosed with RPC. Observations We experienced four cases of RPC in patients aged 24–51 years. All patients exhibited retinal lesions similar to that seen in acute posterior multifocal placoid pigment epitheliopathy or serpiginous choroiditis from the posterior pole to the surrounding region. Although patients underwent systemic prednisolone (PSL) therapy, recurrence was observed and the retinal scar formation was progressive; they were then diagnosed with RPC. In all cases, cyclosporine (CyA) was administered in addition to PSL, no recurrence was observed thereafter. Conclusions and Importance RPC is a rare disease, and a treatment strategy has not yet been established. CyA and PSL combination therapy is considered to be effective in the treatment of RPC.

Abstract
Abstract
[Background]
In patients with node-negative (N0), hormone receptor-positive, human epidermal growth factor receptor (HER2) -negative (luminal) breast cancer, the impact of lymphatic invasion (ly) on the prognosis remains to be clarified.
[Methods]
Among 3,158 patients with primary breast cancers who underwent surgery in our institute from January 2007 to December 2009, we analyzed 1027 N0 luminal invasive breast cancers without preoperative systemic therapy. The luminal breast cancer was defined as hormone receptor-positive (ER of ≥ 10% or PgR of ≥ 10%) and HER2-negative (immunohistochemistry: 0, 1+ or FISH: ratio < 2.0) cancer in the postoperative pathological specimen. ly was defined as positive when cancer cell nests were detected within the lymph duct in the whole specimen. N0 was confirmed pathologically by the sentinel lymph node biopsy in all the patients. The Fisher's exact test was used for comparison between different categories. The distant recurrence rate (DRR) was analyzed using the Kaplan-Meier method and the log-rank test. For multivariate analysis, Cox's regression analysis was performed.
[Results]
The median follow-up period was 103.8 months (range: 5.6-128.8). Recurrence with distant metastasis occurred in 26 patients (2.5%). There were 5 (0.7%) deaths related to breast cancer. ly was detected in 240 patients (23.4%). In the ly-positive group, the tumor size was larger (p = 0.007), and the nuclear grade (NG) was higher (p < 0.001) than in the ly-negative group. Postoperative endocrine therapy (p < 0.001) and postoperative chemotherapy (p < 0.001) were more frequently employed for patients with ly-positive tumor. The univariate analysis showed that ly positivity (p < 0.001), large tumor size (p < 0.001), high NG (p < 0.001), PgR negativity (p = 0.002) and the history of adjuvant chemotherapy (p < 0.001) were associated with high DRR. In the multivariate analysis, large tumor size (p = 0.007) and PgR negativity (p = 0.015) remained significant. Although positive ly had a risk ratio of 2.2, it was not an independent risk factor.When restricted to T1 tumor (n = 899), the aforementioned factors still showed prognostic value in the univariate analysis, among which ly positivity (p = 0.004)remained significant together with PgR negativity (p = 0.047)in themultivariate analysis.The 8-year DRR was very favorable (0.8%) in patients with ly-negative T1N0 tumor while it was modest (6.6%) in patients with ly-positive T1N0 tumor (p < 0.001). Only 1.3% of the patients had received adjuvant chemotherapy in the ly-negative group while 27% of the patients had in the ly-positive group.
[Conclusion]
Lymphatic invasion was associated with higher DRR although it was not independent in the multivariate analysis among patients with N0 luminal breast cancer. When restricted to patients with T1N0 luminal breast cancer, the presence of ly was independently associated with higher risk of distant recurrence. It suggests that the assessment of ly is clinically more relevant when considering treatment options for small luminal breast cancer.

Abstract
Abstract
Background: By definition, ductal carcinoma in situ (DCIS) does not metastasize to the lymph nodes. However, since the introduction of molecular whole-node analysis using the one-step nucleic acid amplification (OSNA) assay for sentinel node (SN) biopsies, the number of DCIS patients with SN metastasis has increased. The clinical management of node-positive DCIS remains controversial because these patients can be treated as different stages based on the pathogenesis: e.g. occult invasive cancer with true nodal metastasis (T1N1) or true DCIS with iatrogenic dissemination of benign or tumor cells into lymph node (TisN0). In this retrospective cohort study, we aimed to elucidate the pathogenesis of nodal metastasis in DCIS and the clinical management of node-positive DCIS.
Patients and Methods: Subjects comprised of 427 patients with a routine postoperative diagnosis of DCIS who underwent SN biopsy using the OSNA assay between 2009 and 2012. The cut-off values of the OSNA assay for negative/positive results and micro/macrometastasis were defined at 250 and 5,000 copies/μL of cytokeratin 19 mRNA, respectively. In the SN-positive patients, all paraffin blocks containing the primary tumor were step-sectioned with 0.5-mm intervals until the tissue was exhausted, and all microscopic slides were examined for detecting occult invasions. Afterwards, the patients were classified into three cohorts based on the SN status and occult invasion: (1) no SN metastasis (TisN0), (2) SN metastasis without occult invasion (TisN1), and (3) SN metastasis with occult invasion (T1N1). Tumor characteristics including risk factors of occult invasions (e.g. large size, comedo-type), prognosis, and SN and non-SN status were compared among the three cohorts. The median follow-up time was 73.6 months.
Results: Of the 427 patients, 408 (95.6%) were SN-negative and 19 (4.4%) were SN-positive. By examining a total of 1,421 step-sectioned slides, 9 of the 19 SN-positive patients had occult invasions in the primary tumors. Overall, 408 (95.6%), 10 (2.3%), and 9 (2.1%) were classified into the TisN0, TisN1, and T1N1 cohorts, respectively. Either of adjuvant endocrine therapy or chemotherapy was given much more in the TisN1 and T1N1 cohorts than in the TisN0 cohort (80.0% and 88.9% vs. 5.4%).Other tumor characteristics were similar among the three cohorts. Although one patients had distant recurrence in the TisN0 cohort, none had locoregional or distant recurrences in the TisN1 and T1N1 cohorts. Regarding the lymph node status in the TisN1 and T1N1 cohorts, median tumor burdens in the SN are 590 and 310 copies/μL, and 2 (20.0%) and 2 (22.2%) patients had additional non-SN metastasis in the axillary dissection materials, respectively.
Conclusions: Tumor characteristics and prognosis were similar among the three cohorts albeit the TisN1 and T1N1 cohorts tended to received adjuvant systemic therapy. Moreover, the SN and non-SN status were similar between the TisN1 and T1N1 cohorts. Therefore, pathogenesis of nodal metastasis in DCIS cannot uniformly be explained, and tumors with different stages may be mixed in the node-positive DCIS. Thus, considering the favorable prognosis of node-positive DCIS, the clinical management should be determined on a case-by-case basis.

Abstract
Abstract
Background: Axillary lymph node status is one of the most powerful prognostic factors in breast cancer. However, it remains unknown which factor of metastatic lymph nodes–the number, tumor volume or anatomical location–is independently prognostic. Conventional pathological examinations of lymph nodes have limited ability to accurately measure metastatic tumor volume due to the partial evaluation of nodes. On the other hand, the one-step nucleic acid amplification (OSNA) assay, a novel molecular method, can quantify the tumor volume in a whole node based on cytokeratin 19 (CK19) mRNA copy number. In this prospective cohort studyusing the OSNA whole-node analysis, we aimed to elucidate the independent prognostic factor of lymph node metastasis in breast cancer.
Patients and Methods: The subjects consisted of 307 cN0 patients with invasive breast cancer, who underwent axillary dissection after a metastatic sentinel node (SN) biopsy and whose SNs and non-SNs were all examined using the OSNA whole-node assaybetween 2009 and 2012.The cut-off values of the OSNA assay for negative/positive results and micro/macrometastasis were defined at 250 and 5,000 copies/μL of CK19 mRNA, respectively. The total tumor volume in the SN or non-SN was defined as the sum of CK19 mRNA copy numbers from all samples in the SN or non-SN. The cut-off value for the total tumor volume in the SN was set at 2,810 copies/μL according to our previous study (Osako et al. Br J Cancer 2017). The anatomical location of metastasis was classified into Level I (confined to SN), Level I (spread to non-SN), or Level II/III. Predictive factors for distant disease-free survival (DDFS) were investigated using the univariate log-rank tests and multivariate Cox proportional hazards models.The median follow-up time was 6.1 years (range, 0.2–8.6).
Results: Of the 307 patients, 130 (42.3%) and 177 (57.7%) had the total tumor volume <2,810 and ≥2,810 copies/μL in the SN, respectively. Five-year DDFS was 96.0% in the entire cohort. In the univariate analysis, DDFS was significantly related to the pT classification, grade, hormone receptor status, triple-negative subtype, total tumor volume in the SN and cytotoxic chemotherapy. However, DDFS was not significantly related to the number of metastatic or macrometastatic nodes in the SN, non-SN, or all nodes (i.e. SN + non-SN); the total tumor volume in the non-SN or all nodes; the AJCC pN classification; or the anatomical location of metastasis. In the multivariate analysis, the total tumor volume in the SN (<2810 vs. ≥2810 copies/μL, hazard ratio 5.2, 95% confidence interval 1.2–23.2, P=0.03) and cytotoxic chemotherapy (- vs. +, hazard ratio 0.05, 95% confidence interval 0.02–0.17, P<0.001) remained significant.
Conclusions: The total tumor volume in the SN was the independent prognostic factor of lymph node metastasis in SN-positive invasive breast cancer. Accurate evaluation of metastatic tumor burden in the SN can be important for predicting prognosis and may help to guide the precise therapeutic decision making for breast cancer patients.

Abstract
Abstract
Background: Previous studies demonstrated that the incidence rate of invasive contralateral breast cancer (CBC) was 5% within the first 10 years after the primary breast cancer (BC). However improving long-term breast cancer survivorship and advancements in diagnostic imaging have resulted in an increased detection of bilateral breast cancer (BBC), and trends of bilateral invasive and in situ breast cancer are not well established. The aim of this study was to assess national trends of BBC incidence of the United States (US) and Japan.
Methods: The Surveillance, Epidemiology, and End Results (SEER) database (1973-2014) and the clinical database of Breast Oncology Center of Cancer Institute Hospital in Tokyo, Japan (Ganken) database (1946-2015) were used to identify nSEER=11,771 and nGanken=1,499 women diagnosed with BBC, respectively. BBC was defined as invasive BC and/or ductal or lobular carcinoma in situ diagnosed in both breasts simultaneously or after primary breast cancer diagnosis. BBC was grouped into synchronous or metachronous BBC by the interval between first BC and contralateral BC; synchronous cases were defined as CBC diagnosed at the same time or within an interval of 1 year from primary BC diagnosis whereas metachronous cases were defined as a diagnosis occuring 1 year following the primary BC. We assessed trends of BBC incidence and characteristics of BBC cases between the two countries. To determine temporal trends in the incidence of BBC and proportion of the characteristics, we compared them using the Cochrane-Armitage test for trend.
Results: The rates of BBC have significantly increased in both countries (Table 1, 2) [1975: 2.6%; 2014: 7.5% in SEER (p<0.001), 1946-1980: 3.3%; 2011-2015: 10.7% in Ganken (p<0.001)]. The increase was identified in both synchronous and metachronous BBC. In SEER, 40% of synchronous BBC were found as in situ BC and about 15% of BBC presented as invasive lobular carcinoma. More recently, CBC was more likely to be diagnosed at early stages (in situ and local disease) than in previous years [1975: 65%; 2014: 85% in SEER (p<0.001)]. The interval between first BC and contralateral BC have shortened, and CBC were more likely to be operated simultaneously in both countries [1985: 40%; 2014: 51% in SEER, 1946-1980: 24%; 2011-2015: 74% in Ganken].

Conclusion: In the modern era, the number of BBC cases have increased and are more likely to be found at an early stage. Further studies are needed to demonstrate the usefulness of early detection of CBC and to define the best means to tailor therapy for patients with bilateral disease.

Abstract
Abstract
Background: Docetaxel + Trastuzumab (H) + Pertuzumab (P) provided progression-free survival (PFS) and overall survival (OS) benefits in HER2-positive advanced or metastatic breast cancer (AMBC) in the CLEOPATRA study as a first-line therapy. However, long-term administration of docetaxel at a dose of 75 mg/m2 every 3 weeks in AMBC patients (pts) is difficult due to the toxicities. Eribulin mesylate (E) is a well-tolerated microtubule inhibitor, and we have reported the efficacy and safety of EHP regimen as first- and second-line therapy for AMBC in a multicenter, phase II study (JBCRG-M03/UMIN000012232). In this M06 study, we address the clinical question as to which is the better chemotherapy partner for HP as first line regimen, in terms of efficacy, toxicity and QOL.
Methods: JBCRG-M06 is a multicenter open-label randomized phase III study for HER2-positive AMBC pts who have received no prior chemotherapy except for the HER2- Antibody-Drug Conjugate (ADC). Pts will be randomized 1:1 to E (1.4mg/m2 on day 1 and 8) + H (8 mg/kg loading dose followed by 6 mg/kg) +P (840 mg loading dose followed by 420 mg) q3wks or standard taxanes (docetaxel 75mg/m2 on day1 or paclitaxel 80mg/m2 on day 1, 8 and 15) + HP q3wks. Stratification factors for randomization are; presence of visceral metastases, number of prior taxanes on perioperative adjuvant treatment, and treatment with prior anti-HER2-ADC. Primary endpoint is PFS and secondary endpoints include overall response rate, duration of response, OS, patient-reported outcomes (PRO) relating to QOL and peripheral neuropathy, new-metastases free survival, and safety. Translational research to search for biomarker for individual precision therapy will be performed. Main eligibility criteria are as follows: pts with HER2-positive AMBC, female aged 20-70 years old, ECOG PS of 0-1, LVEF ≥ 50% at baseline and adequate organ function. Pts who had progressive MBC within 6 months after the end of primary adjuvant systemic chemotherapy are excluded. The sample size was calculated by type1 error (2-sided) of 0.05 and 80% power to estimate the noninferiority margin 1.33 with an expected median PFS of 14.2 months. The target number of pts is 480 recruited over the duration of 3-years. The first patient in was achieved on August 2017. (ClinicalTrials.gov Identifier:NCT03264547).

Abstract
Abstract
[Background] JBCRG-16 (NeoLath) study is a five-arm study to evaluate the efficacy and safety of lapatinib and trastuzumab (6 weeks) followed by lapatinib and trastuzumab plus weekly paclitaxel (12 weeks) with/without prolongation of anti-HER2 therapy prior to chemotherapy (18 vs. 6 weeks), and with/without endocrine therapy in patients with HER2+ and/or estrogen receptor (ER)+ disease. The primary endpoint was pathological complete response (pCR) rate and pCR rate was 47.9% (Masuda N, et al. Breast Cancer, 2018). It is recently reported that microRNAs (miRNAs) are stably present in serum and potentially useful in the diagnosis and evaluation of treatment of cancer. We performed exploratory analysis of detecting pCR by comprehensive analysis of serum miRNAs.
[Materials and Methods] Serum samples were obtained from study participants who received neoadjuvant systemic therapy with trastuzumab, lapatinib and paclitaxel. Before profiling of miRNAs, the overall serum samples were randomly devided in two sets, namely the training set and the testing set with pCR or non-pCR. Pathological complete response (pCR) was defined as the absence of residual invasive cancer of the resected breast specimen and all sampled regional lymph nodes. Total RNA was extracted from a 300 ul serum sample using 3D-Gene® RNA extraction reagent from a liquid sample kit. A comprehensive quantitative expression analysis of miRNA was performed using the by DNA chip 3D-Gene®, which was designed to detect 2565 miRNA sequences registered in miRBase release 21 (http://www.mirbase.org/). The expression level of miRNAs were normalized by internal control (miR-2861, miR-149-3p and miR-4463). Clinicopathological data was retrieved from trial data.
[Results] A total of 112 samples were obtained. Seventy were used in the training set and others were used in the testing set. Median age was 54 years (range 26-70). Sixty-five (58%) patients were pre-menopausal. ER was positive in 59 patients (52.7%). Fourteen (12.5%) were T1c, 78 (69.6%) were T2 and 20 (17.9%) were T3. Fifty-seven (50.9%) patients were node-positive. Fifty-nine (52.7%) patients achieved pCR. The formula with the combination of three miRNAs (miR-A, miR-B, miR-C) was found to be able to predict pCR. This set had a sensitivity of 62.5%, specificity of 86.7% and accuracy of 71.8% in the testing cohort. Area under curve of receiver operationg characteristic curve was 0.753.
[Conclusion] The combination of three miRNAs has potential to predict pCR in patients who received neoadjuvant combination therapy of trastuzumab, lapatinib and paclitaxel in HER2-positive primary breast cancer. The further analysis of changing expression of miRNAs during neoadjuvant therapy is underway and further results will be presented in the symposium.
