RCV000459035 | SCV000553681 | uncertain significance | Neurofibromatosis, type 2 | 2023-04-12 | 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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on NF2 protein function. ClinVar contains an entry for this variant (Variation ID: 412212). 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 arginine, which is basic and polar, with glycine, which is neutral and non-polar, at codon 466 of the NF2 protein (p.Arg466Gly). |
| Ambry Genetics | RCV002393164 | SCV002697671 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-12-04 | criteria provided, single submitter | clinical testing | The p.R466G variant (also known as c.1396C>G), located in coding exon 13 of the NF2 gene, results from a C to G substitution at nucleotide position 1396. The arginine at codon 466 is replaced by glycine, an amino acid with 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. |
