FOXG1 Phenotypes - Human Symptoms

MICROCEPHALY & STRUCTURAL BRAIN ABNORMALITIES

  • Small head size with partial or full loss of the corpus callosum (inhibiting communication of left and right brain)

EPILEPSY/SEIZURES

  • Infantile spasms and life-threatening seizures resistant to drug and surgical treatments.

PHYSICAL DISABILITY

  • Low muscle tone leads to inability to sit, walk, talk or use hands purposefully.

  • Strabismus, poor eye contact and cortical visual impairment.

FEEDING ISSUES

  • Low muscle tone leads to reflux and constipation.

  • Most patients require feeding tube placement.

ASSOCIATED CONDITIONS & DISORDERS

  • Autism Spectrum Disorders (ASD)

  • Sensory Processing Disorder (SPD)

  • Movement disorders

FOXG1 Explained

  • FOXG1 syndrome is a monogenic neurological orphan disorder caused by a mutation in the FOXG1 gene.

  • FOXG1 was formerly named Brain Factor 1 due to being the first and most fundamental gene formed during human development.

  • FOXG1 encodes the Forkhead Box G1 protein.

  • FOXG1 is a transcription factor gene - it transcodes data to tell our brain how to grow cells and contributes to development of the telencephalon, which is an embryonic structure that gives rise to the cerebrum.

  • Cerebrum is the most important part of the brain - it controls cognition (walking, talking, thinking).

  • The following pathogenic variants have been observed in FOXG1 syndrome patients; deletions, duplications, missense, truncation and frameshift variants.

Why FOXG1 is an excellent candidate for biotech investment:

  • FOXG1 syndrome is caused by just one singular gene - FOXG1.

  • FOXG1 is a small gene made up of a single exon. Therefore, it can be easily packaged into most viral vectors used in gene therapy.

  • FOXG1 is a straightforward gene. It’s biological mechanisms are less complex than many other genes affecting the brain.

  • FOXG1 expression is restricted to specific regions in the brain; therefore systemic therapies are not indicated and a tailored strategy can be employed - also making gene therapy more viable. 

  • FOXG1 dysfunction has been linked to various other conditions like autism, Alzheimer’s and schizophrenia, suggesting that therapy development may be transferable to more common disorders.

​

These reasons make FOXG1 an easier, less-risky gene for biotechnology companies to test therapies and experiment on.  Success can be more easily attained than when working with many other genes.  And a fix to FOXG1 could have broad impact on a plethora of other conditions.

FOXG1 is linked to Major Brain disorders

Research shows FOXG1 plays a role in autism, Alzheimer’s, schizophrenia and epilepsy.

This article led by scientist Dr. Flora Vaccarino at Yale University showcases FOXG1 plays a critical role in the development of autism spectrum disorders (ASD).

​

  • ASD affects 1 out of 68 children in the United States alone.

  • FOXG1 could be a viable drug target for ASD as lowering FOXG1 expression has shown to reverse ASD symptoms.

  • Patients with greater head size, and more severe ASD symptoms, had greater expression of FOXG1.
