RCV001984642 | SCV002214032 | uncertain significance | Neurofibromatosis, type 1 | 2021-08-22 | criteria provided, single submitter | clinical testing | Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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. This variant has not been reported in the literature in individuals affected with NF1-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces isoleucine with methionine at codon 967 of the NF1 protein (p.Ile967Met). The isoleucine residue is moderately conserved and there is a small physicochemical difference between isoleucine and methionine. |
| Ambry Genetics | RCV002441072 | SCV002746828 | uncertain significance | Hereditary cancer-predisposing syndrome; Cardiovascular phenotype | 2017-10-06 | criteria provided, single submitter | clinical testing | The p.I967M variant (also known as c.2901A>G), located in coding exon 22 of the NF1 gene, results from an A to G substitution at nucleotide position 2901. The isoleucine at codon 967 is replaced by methionine, an amino acid with highly similar 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. |
