GeneDx RCV000484885 SCV000571517 likely pathogenic not provided 2018-06-08 criteria provided, single submitter clinical testing The R102Q variant in the SCN2A gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The R102Q variant 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 R102Q 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. In silico analysis predicts this variant is probably damaging to the protein structure/function. This substitution is predicted to be within the N-terminal cytoplasmic domain. Therefore, we interpret R102Q as a likely pathogenic variant.
