GeneDx RCV000498672 SCV000590186 uncertain significance not provided 2019-01-17 criteria provided, single submitter clinical testing A variant of uncertain significance has been identified in the COL9A2 gene. The R375G variant has not been published as pathogenic or been reported as benign to our knowledge. This variant is observed in 11/8630 (0.13%) alleles from individuals of European ancestry in the Exome Aggregation Consortium (ExAC) dataset (Lek et al., 2016; Exome Variant Server). This substitution occurs at a position that is not conserved across species. In silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. Nevertheless, the R375G variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties.
