Color Diagnostics, LLC DBA Color Health RCV001182750 SCV001348309 uncertain significance Cardiomyopathy 2020-10-20 criteria provided, single submitter clinical testing This missense variant replaces valine with phenylalanine at codon 81 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 cardiovascular disorders in the literature. This variant has been identified in 1/31400 chromosomes 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 RCV001297131 SCV001486117 uncertain significance Hypertrophic cardiomyopathy 2023-02-06 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: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 922600). This missense change has been observed in individual(s) with hypertrophic cardiomyopathy (PMID: 27532257). This sequence change replaces valine, which is neutral and non-polar, with phenylalanine, which is neutral and non-polar, at codon 81 of the MYBPC3 protein (p.Val81Phe). This variant is present in population databases (no rsID available, gnomAD 0.007%).
