Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	RCV000038062	SCV000061728	likely benign	not specified	2020-04-20	criteria provided, single submitter	clinical testing	The p.Glu1740Lys variant in DSP is classified as likely benign because it has been identified in 0.2% (73/35312) of Latino and 0.18% (229/129084) of European chromosomes, including 1 homozygous individual by gnomAD (http://gnomad.broadinstitute.org). It has also been reported in >10 individuals with a range of cardiomyopathy phenotypes (ARVC, DCM, HCM, RCM, Brugada syndrome, ventricular tachycardia), and it has segregated with Brugada syndrome in 1 affected relative from 1 family (Cox 2011, Allegue 2015, Bottillo 2016, LMM data). However, these diseases have different underlying molecular mechanisms, and furthermore, several of these probands were compound or double heterozygous with a presumed pathogenic variant. In summary, this variant is likely benign due to its elevated frequency in the general population, presence of phenotypes with different underlying molecular mechanisms in reported cases, as well as cases that had other more likely causative variants identified. ACMG/AMP Criteria applied: BS1, BP5, BP4.

A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases allowed determination this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign.
