ClinGen Cardiomyopathy Variant Curation Expert Panel	RCV000758058	SCV000564487	benign	Cardiomyopathy	2016-12-15	reviewed by expert panel	curation	The filtering allele frequency of the c.2967T>C (p.Ile989=) variant in the MYH7 gene is 70.48% (7476/10406) 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).

GeneDx	RCV000035835	SCV000170522	benign	not specified	2012-09-25	criteria provided, single submitter	clinical testing	This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.

Ambry Genetics	RCV000246682	SCV000317659	benign	Cardiovascular phenotype	2015-06-16	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	RCV000355361	SCV000386095	benign	Dilated cardiomyopathy 1S	2018-01-13	criteria provided, single submitter	clinical testing	This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease.

Department of Pathology and Laboratory Medicine, Sinai Health System	RCV001356126	SCV001551199	uncertain significance	not provided		no assertion criteria provided	clinical testing	13 reputable source/s reports the variant as benign, but the evidence is not available to the laboratory to perform an independent evaluation. Allele frequency is common in at least one population database (frequency: 71.843% in ExAC) based on the frequency threshold of 0.637% for this gene. Variant was observed in a homozygous state in population databases more than expected for disease. A synonymous variant not located in a splice region.
