Invitae | RCV000632302 | SCV000753478 | uncertain significance | Neurofibromatosis, type 1 | 2023-12-13 | criteria provided, single submitter | clinical testing | This sequence change replaces glutamine, which is neutral and polar, with arginine, which is basic and polar, at codon 282 of the NF1 protein (p.Gln282Arg). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with NF1-related conditions. ClinVar contains an entry for this variant (Variation ID: 527438). 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 NF1 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 | RCV002343217 | SCV001178994 | uncertain significance | Hereditary cancer-predisposing syndrome; Cardiovascular phenotype | 2022-03-02 | criteria provided, single submitter | clinical testing | The p.Q282R variant (also known as c.845A>G), located in coding exon 8 of the NF1 gene, results from an A to G substitution at nucleotide position 845. The glutamine at codon 282 is replaced by arginine, an amino acid with highly similar properties. This amino acid position is well 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. |
