Labcorp Genetics (formerly Invitae), Labcorp RCV001224294 SCV001396482 uncertain significance Neurofibromatosis, type 1 2019-06-30 criteria provided, single submitter clinical testing 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. This variant disrupts the p.Leu1932Arg amino acid residue in NF1. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 2114220, 12522551, Invitae). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with NF1-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces leucine with arginine at codon 1932 of the NF1 protein (p.Leu1932Arg). The leucine residue is moderately conserved and there is a moderate physicochemical difference between leucine and arginine.
