Color Diagnostics, LLC DBA Color Health RCV000769357 SCV001358254 uncertain significance Cardiomyopathy 2023-05-05 criteria provided, single submitter clinical testing This missense variant replaces serine with asparagine at codon 201 of the MYBPC3 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with MYBPC3-related disorders in the literature. This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance.
Invitae RCV001371391 SCV001567951 uncertain significance Hypertrophic cardiomyopathy 2022-07-12 criteria provided, single submitter clinical testing This sequence change replaces serine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 201 of the MYBPC3 protein (p.Ser201Asn). 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: 626520). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest 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.
