RCV000812789 | SCV000953114 | uncertain significance | Retinoblastoma | 2023-11-13 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with glycine, which is neutral and non-polar, at codon 320 of the RB1 protein (p.Arg320Gly). This variant is present in population databases (rs121913300, gnomAD 0.02%). This missense change has been observed in individual(s) with breast cancer (PMID: 28580595). ClinVar contains an entry for this variant (Variation ID: 656384). 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) performed at Invitae indicates that this missense variant is not expected to disrupt RB1 protein function with a negative predictive value of 80%. 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 | RCV002381810 | SCV002695651 | likely benign | Hereditary cancer-predisposing syndrome | 2022-11-01 | 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. |
