RCV000522355 | SCV000620102 | uncertain significance | not provided | 2017-08-17 | criteria provided, single submitter | clinical testing | The I1390T variant in the SCN2A gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The I1390T variant is not observed at a significant frequency in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The I1390T 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 in mammals. In silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. We interpret I1390T as a variant of uncertain significance |
