Invitae RCV000535747 SCV000627203 uncertain significance Osteogenesis imperfecta type I 2017-06-19 criteria provided, single submitter clinical testing This sequence change replaces aspartic acid with glutamic acid at codon 76 of the COL1A1 protein (p.Asp76Glu). The aspartic acid residue is weakly conserved and there is a small physicochemical difference between aspartic acid and glutamic acid. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with a COL1A1-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; Align-GVGD: "Class C0". The glutamic acid amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. In summary, this variant has uncertain impact on COL1A1 function. The available evidence is currently insufficient to determine its role in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
