Invitae RCV000559490 SCV000628572 uncertain significance Neurofibromatosis, type 1 2017-04-06 criteria provided, single submitter clinical testing This sequence change replaces methionine with threonine at codon 1388 of the NF1 protein (p.Met1388Thr). The methionine residue is moderately conserved and there is a moderate physicochemical difference between methionine and threonine. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with an NF1-related disease. 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. In summary, this variant is a novel missense change that is not predicted to affect protein function. 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.
