Ambry Genetics RCV002323162 SCV002632657 uncertain significance Cardiovascular phenotype 2021-12-16 criteria provided, single submitter clinical testing The p.L1363M variant (also known as c.4087C>A), located in coding exon 27 of the MYH6 gene, results from a C to A substitution at nucleotide position 4087. The leucine at codon 1363 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 tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
Labcorp Genetics (formerly Invitae), Labcorp RCV003094514 SCV003466748 uncertain significance Hypertrophic cardiomyopathy 14 2022-05-22 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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals affected with MYH6-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces leucine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 1363 of the MYH6 protein (p.Leu1363Met).
