Ambry Genetics	RCV000619644	SCV000734914	likely benign	Cardiovascular phenotype	2019-01-21	criteria provided, single submitter	clinical testing	This alteration is classified as likely benign based on a combination of the following: population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.

Women's Health and Genetics/Laboratory Corporation of America, LabCorp	RCV000181169	SCV001554536	benign	not specified	2021-03-25	criteria provided, single submitter	clinical testing	Variant summary: DSC2 c.2636A>G (p.Asp879Gly) results in a non-conservative amino acid change located in the Cadherin, cytoplasmic domain (IPR000233) of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.00022 in 252158 control chromosomes. The observed variant frequency is approximately 22 fold of the estimated maximal expected allele frequency for a pathogenic variant in DSC2 causing Arrhythmia phenotype (1e-05), strongly suggesting that the variant is benign. To our knowledge, no occurrence of c.2636A>G in individuals affected with Arrhythmia and no experimental evidence demonstrating its impact on protein function have been reported. Five clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation and a majority consensus of likely benign (n=4). Based on the evidence outlined above, the variant was classified as benign.
