Invitae RCV001071028 SCV001236310 pathogenic Osteogenesis imperfecta type I 2019-12-14 criteria provided, single submitter clinical testing Glycine residues within the Gly-Xaa-Yaa repeats of the triple helix domain are required for the structure and stability of fibrillar collagens (PMID: 7695699, 8218237, 19344236). In COL1A1, variants affecting these glycine residues are significantly enriched in individuals with disease (PMID: 9016532, 17078022) compared to the general population (ExAC). For these reasons, this variant has been classified as Pathogenic. This variant has been observed in individual(s) with COL1A1-related conditions (PMID: 30614853, Invitae). This variant is not present in population databases (ExAC no frequency). This sequence change replaces glycine with alanine at codon 485 of the COL1A1 protein (p.Gly485Ala). The glycine residue is highly conserved and there is a small physicochemical difference between glycine and alanine.
