RCV000814186 | SCV000954587 | uncertain significance | Retinoblastoma | 2022-07-14 | criteria provided, single submitter | clinical testing | This sequence change replaces lysine, which is basic and polar, with glutamine, which is neutral and polar, at codon 874 of the RB1 protein (p.Lys874Gln). This variant is present in population databases (rs757818801, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with RB1-related conditions. ClinVar contains an entry for this variant (Variation ID: 657557). 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: "Tolerated"; PolyPhen-2: "Possibly 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. |
| Ambry Genetics | RCV002433970 | SCV002745646 | likely benign | Hereditary cancer-predisposing syndrome | 2023-03-10 | 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. |
