ClinVar – all variants identified as ‘Pathogenic’ or ‘Likely Pathogenic’ by multiple submitters with no conflicting data (i.e. no reports of ‘Benign’, ‘Likely Benign’ or ‘Uncertain Significance’) for hypertrophic cardiomyopathy (HCM; n=158), dilated cardiomyopathy (DCM; n=16), long QT syndrome (LQTS; n=18), catecholaminergic polymorphic ventricular tachycardia (CPVT; n=1), Brugada syndrome (Brs; n=4) or arrhythmogenic right ventricular cardiomyopathy (ARVC; n=22) were extracted from the 20161201 release of ClinVar11 (link) using publically available scripts12 (link).
57 protein-altering variants in MYH7 that have been expertly curated by the ClinGen Inherited Cardiomyopathy expert panel (
A prospective dataset of 327 HCM cases and 625 healthy volunteers recruited to the NIHR Royal Brompton cardiovascular BRU, all phenotypically characterised using cardiac MRI. Samples were sequenced using the IlluminaTruSight Cardio Sequencing Kit1 (link) on the Illumina NextSeq platform. This study had ethical approval (REC: 09/H0504/104+5) and informed consent was obtained for all subjects.
