Invitae | RCV002242706 | SCV001558377 | uncertain significance | Osteogenesis imperfecta type I; Ehlers-Danlos syndrome, classic type, 1 | 2023-11-28 | criteria provided, single submitter | clinical testing | This sequence change replaces glycine, which is neutral and non-polar, with aspartic acid, which is acidic and polar, at codon 1351 of the COL1A2 protein (p.Gly1351Asp). This variant is present in population databases (rs372535479, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with COL1A2-related conditions. ClinVar contains an entry for this variant (Variation ID: 1053944). 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 COL1A2 protein function with a negative predictive value of 95%. 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. |

RCV001732139 | SCV001982455 | uncertain significance | not provided | 2022-04-05 | criteria provided, single submitter | clinical testing | Has not been previously published as pathogenic or benign to our knowledge; Not observed at a significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Not located in the triple helical region, where the majority of pathogenic missense variants occur (HGMD) |
