Invitae RCV001063125 SCV001227959 uncertain significance Neurofibromatosis, type 1 2020-05-06 criteria provided, single submitter clinical testing 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 tyrosine with cysteine at codon 863 of the NF1 protein (p.Tyr863Cys). The tyrosine residue is moderately conserved and there is a large physicochemical difference between tyrosine and cysteine. 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: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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.
Ambry Genetics RCV002451269 SCV002739191 uncertain significance Hereditary cancer-predisposing syndrome; Cardiovascular phenotype 2022-04-06 criteria provided, single submitter clinical testing The p.Y863C variant (also known as c.2588A>G), located in coding exon 21 of the NF1 gene, results from an A to G substitution at nucleotide position 2588. The tyrosine at codon 863 is replaced by cysteine, an amino acid with highly dissimilar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
