Labcorp Genetics (formerly Invitae), Labcorp	RCV000530157	SCV000640350	likely benign	Lethal congenital glycogen storage disease of heart	2024-11-17	criteria provided, single submitter	clinical testing
Illumina Laboratory Services, Illumina	RCV001165269	SCV001327448	uncertain significance	Hypertrophic cardiomyopathy 6	2018-01-12	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.

Color Diagnostics, LLC DBA Color Health	RCV001182239	SCV001347624	likely benign	Cardiomyopathy	2019-03-08	criteria provided, single submitter	clinical testing
Ambry Genetics	RCV002377084	SCV002685544	likely benign	Cardiovascular phenotype	2021-05-10	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.
