GeneDx RCV000523743 SCV000616981 uncertain significance not provided 2017-10-26 criteria provided, single submitter clinical testing A variant of uncertain significance has been identified in the SCN2A gene. The K1084R variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The K1084R variant is not observed at a significant frequency in large population cohorts (Lek et al., 2016). The K1084R variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. However, this substitution alters a conserved position predicted to be in the cytoplasmic loop between the second and third homologous domains. In silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant.
