| Ambry Genetics | RCV003177696 | SCV003864570 | uncertain significance | Cardiovascular phenotype | 2023-01-16 | criteria provided, single submitter | clinical testing | The p.V441M variant (also known as c.1321G>A), located in coding exon 11 of the MYH6 gene, results from a G to A substitution at nucleotide position 1321. The valine at codon 441 is replaced by methionine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |

RCV005101152 | SCV005823459 | uncertain significance | Hypertrophic cardiomyopathy 14 | 2024-10-30 | criteria provided, single submitter | clinical testing | This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 441 of the MYH6 protein (p.Val441Met). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with MYH6-related conditions. ClinVar contains an entry for this variant (Variation ID: 2452922). 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. |
