GeneDx RCV000520682 SCV000618773 uncertain significance not provided 2017-07-07 criteria provided, single submitter clinical testing A variant of uncertain significance has been identified in the MYBPC3 gene. The P108S variant has not been published as pathogenic or been reported as benign to our knowledge. This variant is also not observed in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The P108S variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. However, although this substitution occurs at a position that is largely conserved in mammals, serine (S) is the wild-type residue at this position in at least one mammalian species. Additionally, in silico analysis predicts this variant likely does not alter the protein structure/function.
Color Diagnostics, LLC DBA Color Health RCV001185066 SCV001351207 uncertain significance Cardiomyopathy 2022-10-06 criteria provided, single submitter clinical testing This missense variant replaces proline with serine at codon 108 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 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.
