Labcorp Genetics (formerly Invitae), Labcorp RCV000628997 SCV000749907 uncertain significance Hypertrophic cardiomyopathy 2024-01-29 criteria provided, single submitter clinical testing This sequence change replaces glutamic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 861 of the MYH7 protein (p.Glu861Gly). This variant is present in population databases (no rsID available, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with MYH7-related conditions. ClinVar contains an entry for this variant (Variation ID: 525026). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt MYH7 protein function with a positive predictive value of 95%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
CHEO Genetics Diagnostic Laboratory, Children's Hospital of Eastern Ontario RCV001170273 SCV001332836 uncertain significance Cardiomyopathy 2018-03-27 criteria provided, single submitter clinical testing
Color Diagnostics, LLC DBA Color Health RCV001170273 SCV002053341 uncertain significance Cardiomyopathy 2021-05-04 criteria provided, single submitter clinical testing This missense variant replaces glutamic acid with glycine at codon 861 of the MYH7 protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with cardiovascular disorders in the literature. This variant has been identified in 1/251458 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance.
