GeneDx RCV000523148 SCV000619198 uncertain significance not provided 2017-07-20 criteria provided, single submitter clinical testing A variant of uncertain significance has been identified in the SCN1A gene. The E1971Q variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The E1971Q variant is not observed in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The E1971Q variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. However, this substitution is predicted to be within the C-terminal cytoplasmic domain, where amino acids with similar properties to Glutamic acid are tolerated across species. 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.
