Hypertrophic cardiomyopathy (HCM) is a genetic cardiac muscle disease characterized by clinical and genetic heterogeneity. Genetic testing can reveal the presence of diseasecausing variants in genes encoding sarcomere proteins. However, it yields inconclusive or negative results in 40–60% of HCM cases, owing to, among other causes, technical limitations such as the inability to detect pathogenic intronic variants. Therefore, we aimed to increase the diagnostic yield of molecular analysis for HCM by improving the in-silico detection of intronic variants in MYBPC3 that may escape detection by algorithms normally used with tagged diagnostic panels. We included 142 HCM probands with negative results in Illumina TruSight Cardio panel analysis, including exonic regions of 174 cardiomyopathy genes. Raw data were re-analyzed using existing bioinformatics tools. The spliceogenic variant c.1224-80G > A was detected in three patients (2.1%), leading us to reconsider their molecular diagnosis. These patients showed late onset and mild symptoms, although no peculiar phenotypic characteristics were shared. Collectively, rare spliceogenic MYBPC3 variants may play a role in causing HCM, and their systematic detection should be performed to provide more comprehensive solutions in genetic testing using multigenic panels.

Non-alcoholic fatty liver disease (NAFLD) is currently the fastest growing indication to liver transplantation (LT) in Western Countries, both for end stage liver disease and hepatocellular carcinoma. NAFLDon-alcoholic steatohepatitis (NASH) is often expression of a systemic metabolic syndrome; therefore, NAFLD/NASH patients require a multidisciplinary approach for a proper pre-surgical evaluation, which is important to achieve a post-transplant outcome comparable to that of other indications to LT. NAFLD/NASH patients are also at higher risk of post-transplant cardiovascular events, diabetes, dyslipidemia, obesity, renal impairment and recurrent NASH. Lifestyle modifications, included diet and physical activity, are key to improve survival and quality of life after transplantation. A tailored immunosuppressive regimen may be proposed in selected patients. Development of new drugs for the treatment of recurrent NASH is awaited.
