Ambry Genetics RCV000620348 SCV000740157 uncertain significance Cardiovascular phenotype 2017-05-17 criteria provided, single submitter clinical testing The p.G115E variant (also known as c.344G>A), located in coding exon 3 of the MYBPC3 gene, results from a G to A substitution at nucleotide position 344. The glycine at codon 115 is replaced by glutamic acid, an amino acid with similar properties. This amino acid position is not well conserved in available vertebrate species, and glutamic acid is the reference amino acid in other vertebrate species. 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.
Invitae RCV003748265 SCV004512476 uncertain significance Hypertrophic cardiomyopathy 2024-01-28 criteria provided, single submitter clinical testing This sequence change replaces glycine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 115 of the MYBPC3 protein (p.Gly115Glu). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with MYBPC3-related conditions. ClinVar contains an entry for this variant (Variation ID: 520354). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The glutamic acid amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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.
