Invitae RCV003801778 SCV004597216 uncertain significance Osteogenesis imperfecta type I; Ehlers-Danlos syndrome, classic type, 1 2023-10-20 criteria provided, single submitter clinical testing This sequence change replaces glycine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 1325 of the COL1A2 protein (p.Gly1325Glu). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with osteogenesis imperfecta (PMID: 36709916). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Not Available"; Align-GVGD: "Not Available". The glutamic acid amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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.
