ClinGen Cardiomyopathy Variant Curation Expert Panel	RCV000758070	SCV000564485	benign	Cardiomyopathy	2016-12-15	reviewed by expert panel	curation	The filtering allele frequency of the c.3156G>A (p.Lys1052=) variant in the MYH7 gene is 0.14% (21/10404) of African chromosomes by the Exome Aggregation Consortium (http://exac.broadinstitute.org), which is a high enough frequency to be classified as benign based on thresholds defined by the ClinGen Inherited Cardiomyopathy Expert Panel (BA1; PMID:29300372).
Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	RCV000035842	SCV000059493	likely benign	not specified	2015-03-21	criteria provided, single submitter	clinical testing	p.Lys1052Lys in exon 25 of MYH7: This variant is not expected to have clinical s ignificance because it does not alter an amino acid residue and is not located w ithin the splice consensus sequence. It has been identified in 0.2% (21/10404) o f African chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.bro adinstitute.org; dbSNP rs138294643).

Ambry Genetics	RCV000619565	SCV000739956	likely benign	Cardiovascular phenotype	2016-06-21	criteria provided, single submitter	clinical testing	This alteration is classified as likely 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.
