Rett and Angelman-like Disorders VCEP

The p.Ile229Leu variant occurs in the well-characterized Forkhead functional domain of the FOXG1 gene (PMID 18571142, 28661489) (PM1). The p.Ile229Leu variant in FOXG1 occurs in the de novo state (biological parentage unconfirmed) in an individual with intellectual disability and seizures (Genetic Services Laboratory, University of Chicago internal data)(PM6). Computational prediction analysis tools suggests a deleterious impact; however, this information does not predict clinical significance (PP3). The p.Ile229Leu variant in FOXG1 is absent in gnomAD (PM2_supporting). In summary, the p.Ile229Leu variant in FOXG1 is classified as likely pathogenic for FOXG1 disorder based on the ACMG/AMP criteria (PM1, PM6, PP3, PM2_supporting).

PM6

The p.Ile229Leu variant in FOXG1 occurs in the de novo state (biological parentage unconfirmed) in an individual with intellectual disability and seizures (Genetic Services Laboratory, University of Chicago internal data).

PM1

The p.Ile229Leu variant occurs in the well-characterized Forkhead functional domain of the FOXG1 gene (Forkhead: aa 181-275; PMID 18571142, 28661489).

PP3

Computational prediction analysis tools suggests a deleterious impact; however, this information does not predict clinical significance.

PM2_Supporting

The p.Ile229Leu variant in FOXG1 is absent in gnomAD.
