Invitae | RCV000700763 | SCV000829534 | uncertain significance | Neurofibromatosis, type 2 | 2023-02-16 | criteria provided, single submitter | clinical testing | This sequence change replaces leucine, which is neutral and non-polar, with glutamine, which is neutral and polar, at codon 250 of the NF2 protein (p.Leu250Gln). This variant is present in population databases (no rsID available, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with NF2-related conditions. ClinVar contains an entry for this variant (Variation ID: 577903). 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) performed at Invitae indicates that this missense variant is not expected to disrupt NF2 protein function. 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 | RCV002388309 | SCV002670488 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-02-13 | criteria provided, single submitter | clinical testing | The p.L250Q variant (also known as c.749T>A), located in coding exon 8 of the NF2 gene, results from a T to A substitution at nucleotide position 749. The leucine at codon 250 is replaced by glutamine, an amino acid with dissimilar properties. This amino acid position is conserved. 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. |
