Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine RCV000035892 SCV000059543 likely benign not specified 2010-09-28 criteria provided, single submitter clinical testing This variant is not expected to have clinical significance because it does not a lter an amino acid residue and is not located near a splice junction. Silent var iants can disrupt DNA sequence motifs that are important for mRNA splicing; howe ver, splicing variants are very rare in this gene. Therefore, it is unlikely tha t this variant is disease-causing.
Illumina Laboratory Services, Illumina RCV001112578 SCV001270249 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.
Illumina Laboratory Services, Illumina RCV003320074 SCV001270250 uncertain significance Myosin storage 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, 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 RCV001112580 SCV001270251 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.

Color Diagnostics, LLC DBA Color Health RCV001180868 SCV001345910 likely benign Cardiomyopathy 2018-12-04 criteria provided, single submitter clinical testing
Labcorp Genetics (formerly Invitae), Labcorp RCV001481796 SCV001686146 likely benign Hypertrophic cardiomyopathy 2023-09-29 criteria provided, single submitter clinical testing
Ambry Genetics RCV002326726 SCV002632780 likely benign Cardiovascular phenotype 2018-08-01 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.
