Invitae RCV001901998 SCV002133905 uncertain significance Osteogenesis imperfecta type I; Ehlers-Danlos syndrome, classic type, 1 2023-05-15 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) performed at Invitae indicates that this missense variant is not expected to disrupt COL1A2 protein function. ClinVar contains an entry for this variant (Variation ID: 1362946). 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 glutamine, which is neutral and polar, with arginine, which is basic and polar, at codon 114 of the COL1A2 protein (p.Gln114Arg).
