Description

The Q131K variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. It was not observed in approximately 6,500 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 Q131K variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. This substitution occurs at a position that is conserved across species, and missense variants in nearby residues (R127P; L136P) have been reported in the Human Gene Mutation Database in association with cardiomyoapthy (Stenson et al., 2014). In silico analysis predicts this variant is probably damaging to the protein structure/function.
