| Invitae | RCV001890908 | SCV002163333 | uncertain significance | Hypertrophic cardiomyopathy | 2024-01-24 | criteria provided, single submitter | clinical testing | This sequence change replaces alanine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 627 of the MYH7 protein (p.Ala627Ser). This variant is present in population databases (no rsID available, gnomAD 0.007%). 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: 1390255). 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 not expected to disrupt MYH7 protein function with a negative predictive value of 95%. This variant is found within a region of MYH7 between codons 181 and 937 that contains the majority of the myosin head domain. Missense variants in this region have been shown to be significantly overrepresented in individuals with hypertrophic cardiomyopathy (PMID: 27532257). 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. |
