p.Lys241Glu (AAG>GAG): c.721 A>G in exon 1 in the FOXG1 gene (NM_005249.3). The K241E variant in the FOXG1 gene has not been published as a mutation, nor has it been reported as a benign polymorphism to our knowledge. The K241E variant was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. The K241E 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 predicts this variant is probably damaging to the protein structure/function. Missense mutations in nearby residues (S234P and R244C) have been reported in association with FOXG1-related disorders, supporting the functional importance of this region of the protein. The K241E variant is a good candidate for a disease-causing mutation, however the possibility it may be a rare benign variant cannot be excluded. The variant is found in ,FOXG1 panel(s).
