Laboratory for Molecular Medicine,Partners HealthCare Personalized Medicine RCV000150566 SCV000197818 pathogenic Primary dilated cardiomyopathy; Arrhythmogenic right ventricular cardiomyopathy 2018-01-31 criteria provided, single submitter clinical testing The p.Glu1159fs variant in DSP has been identified in 2 individuals with ARVC an d 1 individual with DCM. It segregated with disease in 5 affected family members from 2 families (Asimaki 2016, LMM data). It was absent from large population s tudies. This variant is predicted to cause a frameshift, which alters the protei n?s amino acid sequence beginning at position 1159 and leads to a premature term ination codon 2 amino acids downstream. This alteration is then predicted to lea d to a truncated or absent protein. Heterozygous loss of function of the DSP gen e is associated with ARVC and DCM. In summary, this variant meets criteria to be classified as pathogenic for ARVC and DCM in an autosomal dominant manner based upon its loss of function impact, case observations, segregation studies, and a bsence from controls. ACMG/AMP Criteria applied: PVS1; PM2; PP1_Moderate; PS4_Su pporting.
