Invitae RCV000533190 SCV000623526 uncertain significance Hypertrophic cardiomyopathy 2023-08-04 criteria provided, single submitter clinical testing This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 490 of the MYBPC3 protein (p.Gly490Arg). This variant is present in population databases (no rsID available, gnomAD no frequency). This missense change has been observed in individual(s) with clinical features of MYBPC3-related conditions (Invitae). ClinVar contains an entry for this variant (Variation ID: 454304). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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.
