Invitae RCV000632282 SCV000753457 uncertain significance Neurofibromatosis, type 1 2018-08-10 criteria provided, single submitter clinical testing This sequence change replaces threonine with alanine at codon 165 of the NF1 protein (p.Thr165Ala). The threonine residue is moderately conserved and there is a small physicochemical difference between threonine and alanine. This variant is not present in population databases (ExAC no frequency). This variant has been reported in an individual affected with neurofibromatosis type 1; however, it was inherited from an unaffected parent (PMID: 27838393). ClinVar contains an entry for this variant (Variation ID: 186745). 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 and their clinical significance is uncertain. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
