RCV000686211 | SCV000813720 | uncertain significance | Hypertrophic cardiomyopathy 14 | 2024-11-13 | criteria provided, single submitter | clinical testing | This sequence change replaces valine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 314 of the MYH6 protein (p.Val314Ala). This variant is present in population databases (rs367952105, gnomAD 0.02%). This missense change has been observed in individual(s) with dilated cardiomyopathy (PMID: 31983221). ClinVar contains an entry for this variant (Variation ID: 566408). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt MYH6 protein function with a negative predictive value of 80%. 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. |
Ambry Genetics | RCV002369824 | SCV002685022 | uncertain significance | Cardiovascular phenotype | 2024-05-16 | criteria provided, single submitter | clinical testing | The p.V314A variant (also known as c.941T>C), located in coding exon 9 of the MYH6 gene, results from a T to C substitution at nucleotide position 941. The valine at codon 314 is replaced by alanine, an amino acid with similar properties. This alteration has been reported in a dilated cardiomyopathy (DCM) cohort; however, clinical details were limited (Mazzarotto F et al. Circulation, 2020 02;141:387-398). This amino acid position is not well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this variant remains unclear. |
