Rett and Angelman-like Disorders VCEP

The p.Leu189Val variant occurs in the well-characterized Forkhead functional domain of the FOXG1 gene (PM1). The p.Leu189Val variant in FOXG1 is absent from gnomAD (PM2_supporting). Computational prediction analysis tools suggests a deleterious impact; however, this information does not predict clinical significance on its own (PP3). A pathogenic missense variant (p.Leu189Phe) has been previously identified within this codon which indicates that this residue is critical to the function of the protein (PMID 28661489, GeneDx internal database)(PM5). In summary, the p.Leu189Val variant in FOXG1 is classified as likely pathogenic for a FOXG1-related disorder based on the ACMG/AMP criteria (PM1, PM2_supporting, PP3, PM5).

PM2_Supporting
