RCV000809133 | SCV000949274 | uncertain significance | Familial acute necrotizing encephalopathy | 2020-02-02 | criteria provided, single submitter | clinical testing | This sequence change replaces glutamine with leucine at codon 1503 of the RANBP2 protein (p.Gln1503Leu). The glutamine residue is moderately conserved and there is a moderate physicochemical difference between glutamine and leucine. 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. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0". The leucine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with RANBP2-related disease. This variant is not present in population databases (ExAC no frequency). |
| Ambry Genetics | RCV004028661 | SCV004934404 | likely benign | not specified | 2023-12-08 | criteria provided, single submitter | clinical testing | This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. |
