Genes affected

FOXG1 (HGNC:3811): (forkhead box G1) This locus encodes a member of the fork-head transcription factor family. The encoded protein, which functions as a transcriptional repressor, is highly expressed in neural tissues during brain development. Mutations at this locus have been associated with Rett syndrome and a diverse spectrum of neurodevelopmental disorders defined as part of the FOXG1 syndrome. This gene is disregulated in many types of cancer and is the target of multiple microRNAs that regulate the proliferation of tumor cells. [provided by RefSeq, Jul 2020]

Collection Method:clinical testing

The c.463_465delGAG variant (also known as p.E155del) is located in coding exon 1 of the FOXG1 gene. This variant results from an in-frame GAG deletion at nucleotide positions 463 to 465. This results in the in-frame deletion of a glutamic acid at codon 155. This nucleotide position is not well conserved in available vertebrate species. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

Significance:Benign

Review Status:reviewed by expert panel

Collection Method:curation

The highest population minor allele frequency of the p.Glu155del variant in FOXG1 in gnomAD v4.1 is 0.0003552 in the African/African-American population, which is higher than the ClinGen Rett and Angelman-like Disorders VCEP threshold (≥0.0003) for BA1, and therefore meets this criterion (BA1). In summary, the p.Glu155del variant in FOXG1 is classified as Benign based on the ACMG/AMP criteria (BA1). (FOXG1 Specifications v.4.1; curation approved on [06/25/2025]) -
