GeneDx RCV000158747 SCV000208682 likely pathogenic not provided 2018-12-04 criteria provided, single submitter clinical testing The I201T likely pathogenic variant in the MYH7 gene has been reported previously in association with DCM (Villard et al., 2005; Pugh et al., 2014; Walsh et al., 2017). Initially, I201T was reported in a female proband with DCM and her two affected family members (Villard et al., 2005). This variant has also been identified in multiple other unrelated individuals referred for cardiomyopathy genetic testing at GeneDx, and was found to segregate with disease in three affected relatives from unrelated families. This variant is not observed in large population cohorts (Lek et al., 2016). The I201T 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. Nevertheless, in-silico analyses, including protein predictors and evolutionary conservation, support that this variant does not alter protein structure/function.
