There is no indication that it causes disease, but the available evidence is currently insufficient to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a SCN2A-related disease. This sequence change replaces threonine with isoleucine at codon 699 of the SCN2A protein (p.Thr699Ile). The threonine residue is weakly conserved and there is a moderate physicochemical difference between threonine and isoleucine.
