Rett and Angelman-like Disorders VCEP

The p.Gln86Argfs variant in FOXG1 is predicted to cause a premature stop codon that leads to a truncated or absent protein in a gene where loss-of-function is an established mechanism. There is significant evidence that loss of this region of the gene is pathogenic (PVS1). The p.Gln86Argfs variant in FOXG1 has been reported in at least 2 de novo occurrences (biological parentage unconfirmed) in individuals with FOXG1 disorder (PMID 22739344, 2634418) (PM6_strong, PP4). This variant has been observed in at least 3 other individuals with FOXG1 disorder (PMID 22739344, 26344814) (PS4_moderate). The c.256delC variant in FOXG1 is absent from gnomAD (PM2_supporting). In summary, the p.Gln86Argfs variant in FOXG1 is classified as Pathogenic for FOXG1 disorder based on the ACMG/AMP criteria (PVS1, PM6_strong, PS4_moderate, PM2_supporting, PP4).

PM6_Strong

The c.256delC variant in FOXG1 appears to be de novo in two patients with a clinical phenotype suggestive of a FOXG1-related disorder (PMID 22739344, 2634418)

The c.256delC variant in FOXG1 occurs in the unconfirmed de novo state in this individual with Rett-like syndrome. PubMed:22739344

The c.256delC variant in FOXG1 occurs in the unconfirmed de novo state in this individual with microcephaly, developmental delay, intellectual disability, hypotonia, hyperactivity, seizures, and motor disturbances PubMed:26344814

PP4

The patient is reported to have a clinical phenotype suggestive of a FOXG1-related disorder

PVS1

The c.256delC variant in FOXG1 is predicted to cause a premature stop codon that leads to a truncated or absent protein in a gene where loss-of-function is an established mechanism.

PS4_Moderate

The c.256delC (p.Gln86Argfs) variant has been observed in at least 3 other individuals with FOXG1-related disease (PMID 22739344, 26344814).

PM2_Supporting

The c.256delC variant in FOXG1 is absent from gnomAD
