GeneDx RCV000424660 SCV000536498 uncertain significance not provided 2017-01-25 criteria provided, single submitter clinical testing A variant of uncertain significance has been identified in the CBS gene. The H513Q variant has not been published as pathogenic or been reported as benign to our knowledge. H513Q is not observed in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The H513Q variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. Moreover, this substitution occurs at a position that is conserved across species, and in silico analysis predicts this variant is probably damaging to the protein structure/function. Nevertheless, no pathogenic missense variants in nearby residues have been reported in the Human Gene Mutation Database (Stenson et al., 2014), indicating that this region of the gene is not known to harbor disease-causing variants.
