FOXG1 Syndrome

Causes
- Autosomal dominant condition, no reported cases
- All reported cases stem from FOXG1 gene mutations
- Lack of forkhead box G1 protein production
- Missing protein hinders embryonic brain development
Gene characterization
- Cytogenetic Location: 14q13
- BP 28,767,072 to BP 28,770,277
- Missense or nonsense mutation in (q) arm of chromosome 14
- Direct mutation in FOXG1 gene itself
- Missing transcription repressors cause malformed cerebrum
Mode of Inheritance

- All cases reported come from mutation and not by inheritance
- FOXG1 Syndrome is very severe. Affected individuals are unable to reproduce and have children

Autosomal Dominant Pedigree
Population Data
- Second most common cause of intellectual disability after Down syndrome
- 184 cases diagnosed in the world currently
- Occurs almost exclusively in girls
- in the United states, it is estimated to affect 1 in 10,000 girls by age 12.
Faces of FOXG1
- These two have the syndrome
- Not physically noticeable in some.
- some infants will have a small head compared to normal growth
Treatment
- Some methods for controlling symptoms of FOXG1:
- Physical therapy
- Medications include anticonvulsants
Clinical characteristics
- Seizures
- Intellectual disabilities
- absence of speech and language skills
- Impaired development
- Structural brain abnormalities
- head grows more slowly then normal
- Sleep distrubances
- feeding problems
Diagnosis
- Seizures begin as an infant
- Genetic disorder
- Deletion of genetic material
- causes problems in brain development
