RCV001065972 | SCV001230965 | uncertain significance | Neurofibromatosis, type 1 | 2025-01-06 | criteria provided, single submitter | clinical testing | This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 2472 of the NF1 protein (p.Pro2472Ser). 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: 859783). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt NF1 protein function with a negative predictive value of 95%. 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 | RCV002379597 | SCV002671622 | uncertain significance | Hereditary cancer-predisposing syndrome; Cardiovascular phenotype | 2022-11-16 | criteria provided, single submitter | clinical testing | The p.P2472S variant (also known as c.7414C>T), located in coding exon 50 of the NF1 gene, results from a C to T substitution at nucleotide position 7414. The proline at codon 2472 is replaced by serine, 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. |
