FOXG1 Syndrome

FOXG1 syndrome is a rare neurodevelopmental disorder characterized by severe intellectual disability, movement problems, and seizures. Patients often present with an unusually small head size.

Key characteristics and symptoms of FOXG1 syndrome


Intellectual disability: FOXG1 syndrome typically involves severe intellectual disability. Early in life patients have limited eye contact, delayed or absent motor skills, and delayed or absent speech.

Movement problems: Many FOXG1 patients have severe movement problems that limit their ability to walk or sit up on their own. Abnormal and repetitive movements such as handwringing or hand washing are common in FOXG1 patients.


  • Seizures
  • Small head size
  • Speech impairment
  • Feeding problems
  • Behavior problems
  • Sleep difficulties
  • Low muscle tone

How is FOXG1 syndrome diagnosed?

FOXG1 syndrome is suspected based on an assessment of symptoms and is confirmed with genetic testing that identifies a mutation in the FOXG1 gene.

How is FOXG1 Syndrome treated?

Currently there is no cure for FOXG1 syndrome. Patients are treated for their symptoms, not for the underlying cause of the disease. Medications and therapies can be used to alleviate symptoms. There are currently researchers investigating models and analyzing data to better understand FOXG1 so a cure may be found.
