Abstract
Cardiac magnetic resonance imaging (MRI) is an essential tool for the study of hypertrophic cardiomyopathies (HCM) and for differentiating HCM from conditions with increased ventricular wall thickness, such as cardiac storage diseases. Although cardiac MRI is already used for the diagnosis and characterization of some forms of storage diseases involving the myocardium, it has not yet been used to study myocardial involvement in neuronal ceroid lipofuscinosis (NCL). Here, we describe comprehensive cardiac MRI findings in a patient with the CLN3 form of NCL showing basal inferior interventricular septal hypertrophy with maintained indexed LV mass within reference values and low T1-native values. MRI findings support a finding of abnormal storage material within the myocardium in CLN3 disease. We recommend the possible routine use of cardiac MRI for early diagnosis of cardiac involvement in CLN3 disease (also termed juvenile NCL) and to monitor the effects of emerging CLN3 therapies on the myocardium as well.

Abstract
IntroductionClassic onset of CLN1 disease is within the first year of life with developmental arrest, epilepsy and rapid progression. In an atypical variant of CLN1 disease onset is later in the juvenile epoch. Although epilepsy in the juvenile form of CLN1 often is less severe than in typical CLN1, treatment of seizures and status epilepticus may be challenging.Case presentationThe clinical course, misdiagnosis and epilepsy phenotype are presented in a girl with juvenile CLN1. Cognitive and neurologic regression started at age 5.5 years. Epilepsy was a major clinical issue as the patient suffered from focal seizures, recurrent status epilepticus and epilepsia partialis continua. In one episode of refractory status epilepticus, the patient had significant bradycardia associated with the intravenous infusion of levetiracetam. Diagnosis was made at the age of 12 years, based on palmitoyl protein-thioesterase (PPT) enzyme deficiency and genetic testing that documented a homozygous exon missense mutation in the CLN1 gene (PPT1, c.541G>A, p.Val181Met).DiscussionEpilepsy in all NCL patients is a major clinical issue and presumed related to neuronal excitation and epileptogenesis. The treatment of status epilepticus, in juvenile CLN1 patients, presents a particular challenge and requires monitoring of potential serious pharmacologic side effects of therapy.

Abstract
PURPOSE Batten disease or neuronal ceroid lipofuscinosis is the most prevalent neurodegenerative disorder of childhood. Previously reported perioperative complications in children with Batten disease have come mainly from single case reports. The primary aim of the current study was to investigate perioperative complications of patients with Batten disease in the largest cohort known to date. The secondary objective was to characterize the anesthetic management including the use of propofol and to assess its association with adverse events. METHOD We conducted a single center, retrospective descriptive study by querying the hospital's electronic medical record to identify patients with a diagnosis of Batten disease or ICD10 E75.4 who received anesthetic care from December 2014 to May 2019. RESULTS Thirty-five patients who underwent a total of 93 anesthetic encounters (range 1-11) were included in the analysis. A total of 29 adverse events were identified. Hypotension (N = 6, 6.5%) and bradycardia (N = 7, 7.5%) requiring treatment with medications were the most common adverse events. Other adverse events include oxygen desaturation (N = 4, 4.3%), seizures (N = 4, 4.3%), unanticipated hospital or ICU admission (N = 1, 1.1%), PACU phase 1 stay > 120 min (N = 2, 2.2%), hypothermia (N = 4, 4.3%), agitation (N = 1, 1.1%), and laryngospasm requiring treatment (N = 1, 1.1%). The number of preoperative anti-epileptic drugs (AEDs) had a positive correlation with the rate of perioperative adverse events. There was no statistical relationship of adverse events with intraoperative use of propofol (odds ratio 1.03, 95% CI 0.42-2.51). CONCLUSIONS The majority of these patients were managed without clinically significant perioperative complications. As previously reported, bradycardia, hypotension, and hypothermia were the most common adverse events. Routine avoidance of propofol in patients with Batten disease does not appear warranted.

Abstract
The neuronal ceroid lipofuscinoses (NCLs) are mostly seen as diseases affecting the central nervous system, but there is accumulating evidence that they have co-morbidities outside the brain. One of these co-morbidities is a decline in cardiac function. This is becoming increasingly recognised in teenagers and adolescents with juvenile CLN3, but it may also occur in individuals with other NCLs. The purpose of this review is to summarise the current knowledge of the structural and functional changes found in the hearts of animal models and people diagnosed with NCL. In addition, we present evidence of structural changes that were observed in a systematic comparison of the cardiomyocytes from CLN3Δex7/8 mice.

Abstract
CLN2 neuronal ceroid lipofuscinosis is a hereditary lysosomal storage disease with primarily neurological signs that results from mutations in TPP1, which encodes the lysosomal enzyme tripeptidyl peptidase-1 (TPP1). Studies using a canine model for this disorder demonstrated that delivery of TPP1 enzyme to the cerebrospinal fluid (CSF) by intracerebroventricular administration of an AAV-TPP1 vector resulted in substantial delays in the onset and progression of neurological signs and prolongation of life span. We hypothesized that the treatment may not deliver therapeutic levels of this protein to tissues outside the central nervous system that also require TPP1 for normal lysosomal function. To test this hypothesis, dogs treated with CSF administration of AAV-TPP1 were evaluated for the development of non-neuronal pathology. Affected treated dogs exhibited progressive cardiac pathology reflected by elevated plasma cardiac troponin-1, impaired cardiac function and development of histopathological myocardial lesions. Progressive increases in the plasma activity levels of alanine aminotransferase and creatine kinase indicated development of pathology in the liver and muscles. The treatment also did not prevent disease-related accumulation of lysosomal storage bodies in the heart or liver. These studies indicate that optimal treatment outcomes for CLN2 disease may require delivery of TPP1 systemically as well as directly to the central nervous system.

Abstract
Juvenile neuronal-ceroid-lipofuscinosis (JNCL) is a lysosomal storage disease caused by mutations in CLN3. The most frequent mutation is a 1.02-kb deletion that, when homozygous, causes the classical clinical presentation. Patients harboring mutations different than the major deletion show a marked clinical heterogeneity, including protracted disease course with possible involvement of extraneuronal tissues. Cardiac involvement is relatively rare in JNCL and it is usually due to myocardial storage of ceroid-lipofuscinin. Only recently, histopathological findings of autophagic vacuolar myopathy (AVM) were detected in JNCL patients with severe cardiomyopathy. We describe a 35-year-old male showing a delayed-classic JNCL with visual loss in childhood and neurological manifestations only appearing in adult life. He had an unusual CLN3 genotype with an unreported deletion (p.Ala349_Leu350del) and the known p.His315Glnfs*67 mutation. Autophagic vacuolar myopathy was shown by muscle biopsy. At clinical follow-up, moderately increased CPK levels were detected whereas periodic cardiac assessments have been normal to date. Adult neurologists should be aware of protracted JNCL as cause of progressive neurological decline in adults. The occurrence of autophagic vacuolar myopathy necessitates periodic cardiac surveillance, which is not usually an issue in classic JNCL due to early neurological death.

Abstract
Studies on naturally occurring New Zealand and Australian ovine models of the neuronal ceroid-lipofuscinoses (Batten disease, NCLs) have greatly aided our understanding of these diseases. Close collaborations between the New Zealand groups at Lincoln University and the University of Otago, Dunedin, and a group at the University of Sydney, Australia, led to the formation of BARN, the Batten Animal Research Network. This review focusses on presentations at the 14th International Conference on Neuronal Ceroid Lipofuscinoses (Batten Disease), recent relevant background work, and previews of work in preparation for publication. Themes include CLN5 and CLN6 neuronal cell culture studies, studies on tissues from affected and control animals and whole animal in vivo studies. Topics include the effect of a CLN6 mutation on endoplasmic reticulum proteins, lysosomal function and the interactions of CLN6 with other lysosomal activities and trafficking, scoping gene-based therapies, a molecular dissection of neuroinflammation, identification of differentially expressed genes in brain tissue, an attempted therapy with an anti-inflammatory drug in vivo and work towards gene therapy in ovine models of the NCLs. This article is part of a Special Issue entitled: "Current Research on the Neuronal Ceroid Lipofuscinoses (Batten Disease)".

Abstract
We report a 17-year-old female with juvenile neuronal ceroid-lipofuscinosis (NCL) accompanied by hypertrophic cardiomyopathy (HCM) and left ventricular noncompaction (LVNC). Within our knowledge, this is the first reported case of juvenile NCL with LVNC, and the youngest case of HCM diagnosed by ultrasound. Juvenile NCL is a progressive hereditary disease involving multi-organ accumulation of ceroid-lipofuscin; its resulting complications require prompt attention. Due to its relative rarity, its cardiac involvement is not well known. Based on findings from this patient and related juvenile NCL cases, the risk of cardiac involvement tends to increase with age; a high frequency of ventricular hypertrophy has been reported in patients aged older than 20 years of age. Medical progress and comprehensive care have led to longer survival in patients with juvenile NCL, which likely increases the incidence of cardiac involvement. In relation to HCM in other metabolic disorders, attention should be paid to arrhythmias, including repolarization disturbances, sinus node dysfunction and ventricular tachycardia. LVNC is a cardiomyopathy characterized by prominent left ventricular trabeculae and deep intratrabecular recesses, which are associated with diastolic or systolic dysfunction, thromboembolic complications and arrhythmias. From ours and other case reports, we recommend regular follow-up of NCL patients as follows: echocardiography to estimate cardiomyopathy, Holter monitoring to identify arrhythmias, and computed tomography to detect thrombosis from both ventricles. The mechanism of the HCM and LVNC associated with juvenile NCL remains unclear. Our case requires careful follow-up. Prospective studies of the cardiac involvement in juvenile NCL are necessary to further elucidate its pathomechanism.

Abstract
Neuronal ceroid lipofuscinoses (NCLs), a group of genetically distinct fatal neurodegenerative disorders with no treatment or cure, are clinically characterised by progressive motor and visual decline leading to premature death. While the underlying pathological mechanisms are yet to be precisely determined, the diseases share several common features including inflammation, lysosomal lipofuscin deposits and lipid abnormalities. An important hallmark of most common neurodegenerative disorders including Alzheimer's, Parkinson's and motor neuron diseases is deregulation of biologically active metal homeostasis. Metals such as zinc, copper and iron are critical enzyme cofactors and are important for synaptic transmission in the brain, but can mediate oxidative neurotoxicity when homeostatic regulatory mechanisms fail. We previously demonstrated biometal accumulation and altered biometal transporter expression in 3 animal models of CLN6 NCL disease. In this study we investigated the hypothesis that altered biometal homeostasis may be a feature of NCLs in general using 3 additional animal models of CLN1, CLN3 and CLN5 disease. We demonstrated significant accumulation of the biometals zinc, copper, manganese, iron and cobalt in these mice. Patterns of biometal accumulation in each model preceded significant neurodegeneration, and paralleled the relative severity of disease previously described for each model. Additionally, we observed deregulation of transcripts encoding the anti-oxidant protein, metallothionein (Mt), indicative of disruptions to biometal homeostasis. These results demonstrate that altered biometal homeostasis is a key feature of at least 4 genetically distinct forms of NCL disease.

Abstract
Neuronal ceroid lipofuscinoses, the most common fatal childhood neurodegenerative illnesses, share many features with more prevalent neurodegenerative diseases. Neuronal ceroid lipofuscinoses are caused by mutations in CLN genes. CLN6 encodes a transmembrane endoplasmic reticulum protein with no known function. We characterized the behavioural phenotype of spontaneous mutant mice modeling CLN6 disease, and demonstrate progressive motor and visual decline and reduced lifespan in these mice, consistent with symptoms observed in neuronal ceroid lipofuscinosis patients. Alterations to biometal homeostasis are known to play a critical role in pathology in Alzheimer's, Parkinson's, Huntington's and motor neuron diseases. We have previously shown accumulation of the biometals, zinc, copper, manganese and cobalt, in CLN6 Merino and South Hampshire sheep at the age of symptom onset. Here we determine the physiological and disease-associated expression of CLN6, demonstrating regional CLN6 transcript loss, and concurrent accumulation of the same biometals in the CNS and the heart of presymptomatic CLN6 mice. Furthermore, increased expression of the ER/Golgi-localized cation transporter protein, Zip7, was detected in cerebellar Purkinje cells and whole brain fractions. Purkinje cells not only control motor function, an early symptomatic change in the CLN6 mice, but also display prominent neuropathological changes in mouse models and patients with different forms of neuronal ceroid lipofuscinoses. Whole brain fractionation analysis revealed biometal accumulation in fractions expressing markers for ER, Golgi, endosomes and lysosomes of CLN6 brains. These data are consistent with a link between CLN6 expression and biometal homeostasis in CLN6 disease, and provide further support for altered cation transporter regulation as a key factor in neurodegeneration.

Abstract
This article reports the case of a female with late infantile neuronal ceroid lipofuscinosis who developed right and left anterior bundle branch blocks and episodic bradycardia at 23 years of age. Several episodes of supraventricular tachycardia manifested at 23 and 27 years of age. In addition, a transient second-degree atrioventricular conduction block also emerged at 27 years of age. Atrial fibrillation and aggravation of the atrioventricular conduction block resulted in progressive bradycardia and cardiac death at the age of 28 years. Cardiac involvement and accumulation of lipopigments in the myocardium and cardiac conduction system have been recognized in juvenile neuronal ceroid lipofuscinosis, but this is the first report to describe progressive conduction defects in a case of late infantile neuronal ceroid lipofuscinosis.

Abstract
Infantile neuronal ceroid lipofuscinosis (INCL), also known as Santavuori-Haltia disease, is an inherited neurodegenerative disorder caused by a mutation in the gene encoding the lysosomal enzyme palmitoyl-protein-thioesterase-1 (PPT1). Fatty acid-modified proteins are not degraded and accumulate as granular osmiophilic deposits in cells in the central nervous system; patients have blindness, seizures, progressive psychomotor deterioration, and die in early childhood. Although the disease manifests clinically primarily with neurological symptoms, visceral storage also accumulates. A murine model of INCL due to PPT1 deficiency exhibits clinical findings and pathology similar to those seen in patients with INCL. Homozygous PPT1-deficient mice have a shortened life span and neurological abnormalities including seizures, blindness, and mental and motor deficits. Widespread granular osmiophilic deposits (GRODs) accumulate in lysosomes in neurons and glia in the brain, retinal cells, kidney glomerular cells, aortic smooth muscle cells, and, in lesser amounts, in the fixed-tissue macrophage system. Accumulation of GRODs in aortic smooth muscle cells is accompanied by abnormalities in cardiac function and aortic root dilatation. This PPT1-deficient murine model is a well-defined genetic system that can be used to test potential therapies for lysosomal storage disease and to study the pathophysiology of INCL.

Abstract
A 31-year-old woman presented with dyspnea and left-sided chest discomfort and was found to have biventricular heart failure with impaired ventricular filling. Clinically, she was thought to have restrictive cardiomyopathy or constrictive pericarditis. Transmission electron microscopy of myocardial tissue unexpectedly revealed crosshatched, curvilinear, and fingerprint depositions, which were characteristic for neuronal ceroid lipofuscinosis. Cardiac involvement by this inherited disorder is discussed in light of the findings in this patient and in 15 other reported cases.

Abstract
AIM To evaluate the sequelae of the lysosomal storage of globotriaosylceramide (Gb3) in a series of patients with Fabry disease. METHODS Biopsy and post-mortem samples from 12 patients with Fabry disease were examined microscopically, including, in some cases, immunohistochemistry and electron microscopy. Where possible, comparisons were made with other lysosomal storage disorders. RESULTS Storage of Gb3 in cardiocytes leads commonly to progressive hypertrophy, which is a non-specific phenomenon also observed in other lysosomal storage disorders. Capillary endothelial storage was associated with a tendency for capillary basement membrane multiplication. In the single angiokeratoma studied, the basement membrane was rudimentary. Sinusoids in the adrenal cortex and liver displayed either a slight degree of storage or were unaffected. The glomeruli of the kidney exhibited focal hyalinization starting in the mesangial region. Proximal tubular cells were essentially free of lysosomal accumulation, including protein absorption droplets, despite the presence of proteinuria. In only one case, an autopsied Fabry heterozygote, were the proximal tubular cells loaded with protein absorption droplets. The arterial wall in large muscular arteries (coronary, renal and intrarenal) displayed arteriopathy with pronounced involvement of the smooth muscle cells in the media. Arteriopathy started with storage, followed by cell degeneration and breakdown, extracellular matrix deposition and, often, calcification (confined to the muscular layer). Smooth muscle cells occasionally exhibited shrinkage-type necrosis, with dispersion of the stored lipid into the dense cytoplasmic mass. Intimal and mitral valve fibroblasts exhibited variable storage, which was associated with cell loss and necrosis. Intensive storage was found in Leydig cells and in the epididymal epithelium. CONCLUSION These long-term sequelae of Gb3 storage are mostly irreversible. Some may interfere with enzyme replacement therapy. It is important, therefore, to consider starting enzyme replacement therapy as early as possible.

Abstract
We report the clinical details and the pathology of the heart at autopsy of three neuronal ceroid lipofuscinosis (NCL) patients. Two patients were diagnosed as classical juvenile NCL and one as a variant juvenile NCL (JNCL) with granular osmiophilic deposits (GRODs). Cardiac findings during life were retrospectively evaluated and included left ventricular hypertrophy with repolarization disturbances (ECG findings) in two patients with classical JNCL and severe bradycardia with periods of sinus arrest in one of them, severe supraventricular tachycardias during anaesthesia in the variant JNCL-patient. At autopsy myocardial and valvular storage of lipopigments, diagnostic for NCL, was observed histologically and confirmed ultrastructurally in all three cases. In two patients with JNCL the storage was associated with hypertrophy and dilation of both ventricles, degenerative myocardial changes, interstitial fibrosis and fatty replacement. Abundant accumulation and degeneration were seen in all components of the conduction system in three patients, which outreached at several places by far the storage of the adjacent myocardium. Our observations indicate a prominent involvement of the heart in NCL, with preference of storage for the conduction system of the heart.
