GeneDx RCV000518911 SCV000619508 likely pathogenic not provided 2017-07-21 criteria provided, single submitter clinical testing The S200F variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The variant is not observed in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). S200F 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. 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. The S200 residue occurs within the D loop of CYBB, and variants in this region have been shown to eliminate oxidase activity of NADPH oxidase (Li et al., 2005). In summary, this variant is likely pathogenic; however, the possibility that it is benign cannot be excluded.
