However, it has been identified in 0.4% (8/2000) of chromosomes from a broad, though clinically and racially unspecified population (dbSNP rs41272699) and in 1.5% (102/7020) of European American chromosomes and 0.4% (14/3738) of Af rican American chromosomes by the NHBLI Exome sequencing project in a clinical c ohort that included individuals with heart disease (http://evs.gs.washington.edu /EVS). With a frequency this high the variant is considered to be benign.

Ambry Genetics	RCV000250294	SCV000318135	benign	Cardiovascular phenotype	2015-09-15	criteria provided, single submitter	clinical testing	This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, 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.
Illumina Laboratory Services, Illumina	RCV000313133	SCV000427698	likely benign	Dilated cardiomyopathy 1I	2017-04-27	criteria provided, single submitter	clinical testing	This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign.

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.

Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.0094 in 278984 control chromosomes in the gnomAD database, including 28 homozygotes. The observed variant frequency is approximately 375 fold of the estimated maximal expected allele frequency for a pathogenic variant in DES causing Cardiomyopathy phenotype (2.5e-05), strongly suggesting that the variant is benign. c.638C>T has been reported in the literature in individuals affected with Cardiomyopathy as well as in controls. In one study, the variant failed to segregate with disease in a family, being found in 4 healthy individuals and was absent in 1 affected individual (Taylor_2007). In functional studies, cells expressing the variant showed normal complete filamentous network (Bar_2005, Goudeau_2006). Six clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. Multiple laboratories reported the variant with conflicting assessments. Based on the evidence outlined above, the variant was classified as benign.
