The S217F variant in the FOXL2 gene has previously been reported to segregate with disease in at least one family with blepharophimosis-ptosis-epicanthus inversus (De Baere et al., 2001). Adequate data is not available in large population cohorts to assess the frequency of this variant in publicly available databases; however, this variant has not been detected in presumably healthy individuals tested at GeneDx. The S217F 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. This substitution occurs at a position that is 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. Based on currently available evidence, we interpret S217F as a pathogenic variant.
