Forkhead box protein G1 is a protein that in humans is encoded by the FOXG1 gene.[1][2][3]


This gene belongs to the forkhead family of transcription factors which is characterized by a distinct forkhead domain. The specific function of this gene has not yet been determined; however, it may play a role in the development of the brain and telencephalon. It likely causes problems if it is mutated in kids. Mutations cause high levels of mortality.[3]

Cajal Retzius Cell development is regulated by Foxg1

FOXG1 syndrome[edit]

FOXG1 syndrome is characterized by microcephaly and brain malformations. It affects most aspects of development and can cause seizures. FOXG1 syndrome is classified as an Autism Spectrum Disorder and was previously considered a variant of Rett Syndrome.[4][5]


FOXG1 has been shown to interact with JARID1B.[6]
