CHEO Genetics Diagnostic Laboratory, Children's Hospital of Eastern Ontario RCV000770490 SCV000901935 uncertain significance Cardiomyopathy 2023-02-23 criteria provided, single submitter clinical testing
Invitae RCV001069425 SCV001234589 uncertain significance Hypertrophic cardiomyopathy 2023-05-08 criteria provided, single submitter clinical testing 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. 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. ClinVar contains an entry for this variant (Variation ID: 626820). This variant has not been reported in the literature in individuals affected with MYH7-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces asparagine, which is neutral and polar, with tyrosine, which is neutral and polar, at codon 911 of the MYH7 protein (p.Asn911Tyr).
Color Diagnostics, LLC DBA Color Health RCV000770490 SCV001350055 uncertain significance Cardiomyopathy 2020-04-27 criteria provided, single submitter clinical testing This missense variant replaces asparagine with tyrosine at codon 911 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 not been identified 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.
