GeneDx RCV000485371 SCV000573747 likely pathogenic not provided 2017-03-02 criteria provided, single submitter clinical testing A S738C variant that is likely pathogenic was identified in the MYH7 gene. It has not been published as pathogenic or been reported as benign to our knowledge. Additionally, the S738C variant is not observed in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The S738C 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. This substitution occurs at a position that is conserved across species and in silico analysis predicts this variant is probably damaging to the protein structure/function. Furthermore, likely pathogenic variants at the same residue (S738R, S738T), and pathogenic/likely pathogenic missense variants in nearby residues (I736L, I736V, I736T, I736M, G741R, G741W, G741E) have been reported at GeneDx and/or reported in the Human Gene Mutation Database in association with HCM (Stenson et al., 2014), supporting the functional importance of this residue and region of the protein.
