Cover Story: Genetic variants in MYBPC3 are one of the most common causes of hypertrophic cardiomyopathy (HCM). While variants in MYBPC3 affecting canonical splice site dinucleotides are a well-characterised cause of HCM, only recently has work begun to investigate the pathogenicity of more deeply intronic variants. Here, we present three patients with HCM and intronic splice-affecting MYBPC3 variants of unknown significance (VUS) identified from diagnostic DNA sequencing. RNA investigations using in silico bioinformatics prediction tools, in vitro minigene splicing assays and in vivo analysis of patient blood-derived RNA showed that all three variants result in mis-splicing of MYBPC3 and allelic loss-of-function. We can now classify these MYBPC3 intronic variants as pathogenic and offer genetic testing to other family members. Created with BioRender.com. View this paper
