Invitae RCV002241395 SCV001391255 pathogenic Osteogenesis imperfecta type I; Ehlers-Danlos syndrome, classic type, 1 2021-11-19 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. This variant disrupts the p.Cys1272 amino acid residue in COL1A2. Other variant(s) that disrupt this residue have been observed in individuals with COL1A2-related conditions (PMID: 26627451, 27509835, 28725987), which suggests that this may be a clinically significant amino acid residue. 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 expected to disrupt COL1A2 protein function. ClinVar contains an entry for this variant (Variation ID: 948124). This missense change has been observed in individual(s) with autosomal dominant osteogenesis imperfecta (PMID: 33070251; Invitae). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces cysteine, which is neutral and slightly polar, with phenylalanine, which is neutral and non-polar, at codon 1272 of the COL1A2 protein (p.Cys1272Phe).
