Invitae RCV001202983 SCV001374123 pathogenic Ehlers-Danlos syndrome, classic type; Osteogenesis imperfecta type I 2019-08-27 criteria provided, single submitter clinical testing This sequence change replaces glycine with serine at codon 1096 of the COL1A2 protein (p.Gly1096Ser). The glycine residue is highly conserved and there is a small physicochemical difference between glycine and serine. This variant is not present in population databases (ExAC no frequency). This variant has been observed in individual(s) with osteogenesis imperfecta (Invitae). In at least one individual the variant was observed to be de novo. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. This variant disrupts the p.Glu1096 amino acid residue in COL1A2. Other variant(s) that disrupt this residue have been observed in individuals with COL1A2-related conditions (PMID:7749416), which suggests that this may be a clinically significant amino acid residue. For these reasons, this variant has been classified as Pathogenic.
