GeneDx RCV000489222 SCV000577851 likely pathogenic not provided 2015-04-01 criteria provided, single submitter clinical testing The A55S variant has not been published as a pathogenic variant, nor has it been reported as a benign polymorphism to our knowledge. The A55S variant was not observed in approximately 6500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. The A55S 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. Additionally, missense variants in nearby residues (N47K, G57E, R58N) have been reported in the Human Gene Mutation Database in association with HCM (Stenson et al., 2014), supporting the functional importance of this region of the protein. Nevertheless, in silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function.Therefore, this variant is a strong candidate for a pathogenic variant, however the possibility that it is a benign variant cannot be excluded.
