Illumina Laboratory Services, Illumina	RCV000584781	SCV000386215	uncertain significance	Hypertrophic cardiomyopathy 1	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, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease.

Illumina Laboratory Services, Illumina	RCV000297044	SCV000386220	likely benign	MYH7-related skeletal myopathy	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 likely benign is not then subjected to further curation. The score for this variant resulted in a classification of likely benign for this disease.
GeneDx	RCV000035705	SCV000513797	benign	not specified	2015-03-14	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.

Agnes Ginges Centre for Molecular Cardiology, Centenary Institute	RCV000584781	SCV000692490	benign	Hypertrophic cardiomyopathy 1	2016-11-18	criteria provided, single submitter	research	This synonymous variant MYH7 (Lys397=) was identified in a HCM case. However, a known pathogenic variant in a different gene was identified and shown to segregate with disease. Furthermore this variant has been identified >20 times in the Exome Aggregation Consortium dataset (MAF=0.00019; http://exac.broadinstitute.org/). Therefore, we classify this variant as "benign".
Ambry Genetics	RCV000618918	SCV000735681	likely benign	Cardiovascular phenotype	2017-02-08	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.
