Labcorp Genetics (formerly Invitae), Labcorp RCV000204829 SCV000259676 uncertain significance Neurofibromatosis, type 1 2017-01-15 criteria provided, single submitter clinical testing This sequence change replaces asparagine with histidine at codon 1338 of the NF1 protein (p.Asn1338His). The asparagine residue is moderately conserved and there is a small physicochemical difference between asparagine and histidine. In summary, this variant is a rare missense change with uncertain impact on 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. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a NF1-related disease. ClinVar contains an entry for this variant (Variation ID: 219670).
