RCV001572230 | SCV001796833 | uncertain significance | not provided | 2020-01-09 | criteria provided, single submitter | clinical testing | Has not been previously published as pathogenic or benign to our knowledge; Not observed in large population cohorts (Lek et al., 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect; Not located in the triple helical region, where the majority of pathogenic missense variants occur (Stenson et al., 2014) |
Invitae | RCV001866037 | SCV002309651 | uncertain significance | Osteogenesis imperfecta type I; Ehlers-Danlos syndrome, classic type, 1 | 2023-05-03 | criteria provided, single submitter | clinical testing | 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 COL1A2 protein function. ClinVar contains an entry for this variant (Variation ID: 1205539). This variant has not been reported in the literature in individuals affected with COL1A2-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces arginine, which is basic and polar, with leucine, which is neutral and non-polar, at codon 1161 of the COL1A2 protein (p.Arg1161Leu). |
