Invitae | RCV002231025 | SCV000627359 | pathogenic | Osteogenesis imperfecta type I; Ehlers-Danlos syndrome, classic type, 1 | 2016-10-11 | criteria provided, single submitter | clinical testing | This variant is not present in population databases (ExAC no frequency). This variant has been reported in an individual affected with osteogenesis imperfecta type IV (PMID: 17078022). For these reasons, this variant has been classified as Pathogenic. Family studies have indicated that this variant was not present in the parents of an individual with osteogenesis imperfecta, which suggests that it was de novo in that affected individual. This sequence change replaces glycine with aspartic acid at codon 307 of the COL1A2 protein (p.Gly307Asp). The glycine residue is highly conserved and there is a moderate physicochemical difference between glycine and aspartic acid. |
