GeneDx RCV000078972 SCV000329092 pathogenic not provided 2017-09-07 criteria provided, single submitter clinical testing The R246C variant in the ATRX gene (previously published as R129C due to alternative nomenclature) is a recurrent variant that has been identified in multiple unrelated patients with alpha-thalassemia X-linked intellectual disability (Gibbons et al., 1997; Gibbons et al., 2008; Pavone et al., 2010). The R246C mutation 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 R246C 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. In silico analysis predicts this variant is probably damaging to the protein structure/function. We interpret R246C as a disease-causing variant
