Ambry Genetics | RCV000216287 | SCV000276252 | uncertain significance | Hereditary cancer-predisposing syndrome | 2015-06-09 | criteria provided, single submitter | clinical testing | Thep.G1502Svariant (also known as c.4504G>A), located in codingexon34 of theNF1gene, results from a G to A substitution at nucleotide position 4504. Theglycineatcodon1502 is replaced byserine, an amino acid with similar properties. This variant was not reported in population based cohorts in the following databases: Database of Single NucleotidePolymorphisms(dbSNP),NHLBIExomeSequencing Project (ESP), and 1000 Genomes Project. In the ESP, this variant was not observed in 6503 samples (13006 alleles) with coverage at this position. To date, this alteration has been detected with an allele frequency of approximately 0.002% (greater than 55000 alleles tested) in our clinical cohort. 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 p.G1502Sremains unclear. |
Invitae | RCV000632321 | SCV000753498 | uncertain significance | Neurofibromatosis, type 1 | 2023-09-01 | criteria provided, single submitter | clinical testing | This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 1481 of the NF1 protein (p.Gly1481Ser). This variant is present in population databases (no rsID available, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with NF1-related conditions. 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 NF1 protein function. ClinVar contains an entry for this variant (Variation ID: 232189). |
