Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Oct 15, 2016 | In summary, this variant is a novel missense change with uncertain impact on protein function. 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, Align-GVGD) both suggest that this variant is likely to be disruptive, 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 SCN9A-related disease. This sequence change replaces lysine with glutamic acid at codon 1965 of the SCN9A protein (p.Lys1965Glu). The lysine residue is highly conserved and there is a small physicochemical difference between lysine and glutamic acid. - |
