Color Diagnostics, LLC DBA Color Health RCV001190317 SCV001357776 uncertain significance Cardiomyopathy 2023-04-20 criteria provided, single submitter clinical testing This missense variant replaces aspartic acid with valine at codon 1071 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 been identified in 1/207886 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 RCV003748334 SCV004402388 uncertain significance Hypertrophic cardiomyopathy 2023-02-17 criteria provided, single submitter clinical testing The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. 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: 927199). 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 tolerated. 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. This sequence change replaces aspartic acid, which is acidic and polar, with valine, which is neutral and non-polar, at codon 1071 of the MYBPC3 protein (p.Asp1071Val).
