FOXG1 (Forkhead Box G1) is a transcription factor essential for brain development and function. Originally identified as a repressor of forkhead genes, FOXG1 plays critical roles in neural progenitor cell proliferation, neuronal differentiation, and formation of the cerebral cortex. Mutations in FOXG1 cause FOXG1 syndrome, a neurodevelopmental disorder characterized by intellectual disability, seizures, and movement disorders.
