Invitae | RCV001343056 | SCV001537013 | uncertain significance | Neurofibromatosis, type 2 | 2022-09-07 | 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. 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: "Possibly Damaging"; Align-GVGD: "Class C15"). ClinVar contains an entry for this variant (Variation ID: 1039559). This variant has not been reported in the literature in individuals affected with NF2-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces aspartic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 201 of the NF2 protein (p.Asp201Gly). |
Ambry Genetics | RCV002357184 | SCV002660443 | uncertain significance | Hereditary cancer-predisposing syndrome | 2021-10-22 | criteria provided, single submitter | clinical testing | The p.D201G variant (also known as c.602A>G), located in coding exon 7 of the NF2 gene, results from an A to G substitution at nucleotide position 602. The aspartic acid at codon 201 is replaced by glycine, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
