Abstract
BACKGROUND Factors related to the development and severity of polycystic liver disease (PLD) have not been well established. We aimed to evaluate the genetic and epidemiologic risk factors of PLD in patients with autosomal dominant polycystic kidney disease (ADPKD). METHODS Adult patients with inherited cystic kidney disease were enrolled from May 2019 to May 2021. Demographic, clinical, and laboratory data were collected at the initial study visit. The severity of PLD was graded based on the height-adjusted total liver volume: < 1,000 mL/m (Gr1), 1,000-1,800 mL/m (Gr2), and > 1,800 mL/m (Gr3). Targeted exome sequencing was done by a gene panel including 89 ciliopathy-related genes. We searched out the relative factors to the presence and the severity of PLD using logistic regression analysis. RESULTS Of 602 patients with typical ADPKD, 461 (76.6%) patients had PLD. The patients with PLD showed female predominance and a higher frequency of other ADPKD-related complications. The genetic variants with truncating mutation of PKD1 (PKD1-protein-truncating [PT]) or PKD2 commonly affected the development and severity of PLD. An older age, female sex, and higher kidney volume with Mayo classification 1C-1E was significantly associated with the development of PLD, but not with the severity of PLD. On the other hand, higher body mass index, lower hemoglobin, and higher alkaline phosphatase (ALP) were the significant risk factors of severe PLD (≥ Gr2). CONCLUSION Hepatic involvement in ADPKD could be related to kidney manifestations and genetic variants including PKD1-PT or PKD2. Monitoring hemoglobin and ALP and evaluating the genetic variants might help predict severe PLD. TRIAL REGISTRATION Clinical Research Information Service Identifier: KCT0005580.

Abstract
Down Syndrome (DS), caused by triplication of human chromosome 21 (Hsa21) is the most common form of intellectual disability worldwide. Recent progress in healthcare has resulted in a dramatic increase in the lifespan of individuals with DS. Unfortunately, most will develop Alzheimer's disease like dementia (DS-AD) as they age. Understanding similarities and differences between DS-AD and the other forms of the disease - i.e., late-onset AD (LOAD) and autosomal dominant AD (ADAD) - will provide important clues for the treatment of DS-AD. In addition to the APP gene that codes the precursor of the main component of amyloid plaques found in the brain of AD patients, other genes on Hsa21 are likely to contribute to disease initiation and progression. This review focuses on SYNJ1, coding the phosphoinositide phosphatase synaptojanin 1 (SYNJ1). First, we highlight the function of SYNJ1 in the brain. We then summarize the involvement of SYNJ1 in the different forms of AD at the genetic, transcriptomic, proteomic and neuropathology levels in humans. We further examine whether results in humans correlate with what has been described in murine and cellular models of the disease and report possible mechanistic links between SYNJ1 and the progression of the disease. Finally, we propose a set of questions that would further strengthen and clarify the role of SYNJ1 in the different forms of AD.

Abstract
Hereditary motor and sensory neuropathy with proximal predominance (HMSN-P) is a rare degenerative disorder inherited in an autosomal dominant fashion. This disease was described first in Japanese descendants from Okinawa and Shiga prefectures in mainland Honshu in 1997. The disease is characterized by adult onset of proximal weakness and atrophy, muscle cramps, fasciculations, areflexia, high incidence of elevated creatine kinase, hyperlipidemia, and diabetes mellitus, resembling Kennedy disease, though the mode of inheritance is autosomal dominant, rather than X linked. We examined a 56-year-old male patient with clinical features suggestive of HMSN-P and positive family history in an autosomal dominant fashion. Clinical, electrophysiological, and genetic factors were also reviewed. The appearance of HMSN-P in India and elsewhere calls for clinicians in nonendemic regions to be familiar with this rare disorder, which has typically been geographically confined.

Abstract
Fibrodysplasia ossificans progressiva (FOP) is a rare autosomal dominant disorder, characterized by painful swelling of muscles and connective tissue in the early years of life, consequently leading to ossification at a mean age of 4-5 years. We report FOP in a 2-year-old boy with palpable masses in the frontal and lower cervical paraspinal and left periscapular muscles.He was born with hallux valgus. Despite this hallmark, he was referred to the hospital with the primary diagnosis of hematoma, but further investigation indicated FOP. The patient was discharged from the hospital with non steroidal anti-inflammatory drugs (NSAID) and education of the parents. The importance of this case was that in spite of the early occurrence of the typical presentation of FOP for more than one year and the fact that the patient's mother was a physician who had consulted with many specialists, the diagnosis had been missed.This indicates that the general physicians, radiologists and other specialists' awareness and knowledge of FOP is insufficient.

Abstract
The Muenke syndrome (MS) is characterized by unicoronal or bicoronal craniosynostosis, midfacial hypoplasia, ocular hypertelorism, and a variety of minor abnormalities associated with a mutation in the fibroblast growth factor receptor 3 (FGFR3) gene. The birth prevalence is approximately one in 10,000 live births, accounting for 8-10% of patients with coronal synostosis. Although MS is a relatively common diagnosis in patients with craniosynostosis syndromes, with autosomal dominant inheritance, there has been no report of MS, in an affected Korean family with typical cephalo-facial morphology that has been confirmed by molecular studies. Here, we report a familial case of MS in a female patient with a Pro250Arg mutation in exon 7 (IgII-IGIII linker domain) of the FGFR3 gene. This patient had mild midfacial hypoplasia, hypertelorism, downslanting palpebral fissures, a beak shaped nose, plagio-brachycephaly, and mild neurodevelopmental delay. The same mutation was confirmed in the patient's mother, two of the mother's sisters and the maternal grandfather. The severity of the cephalo-facial anomalies was variable among these family members.
