Brunner syndrome is caused by mutations in the [[MAOA]] gene. This gene provides instructions for making an enzyme called monoamine oxidase A, which is involved in the breakdown of certain chemicals in the brain. Mutations in the MAOA gene lead to reduced activity of this enzyme, which can result in an imbalance of chemicals in the brain and the symptoms of Brunner syndrome. | Brunner syndrome is caused by mutations in the [[MAOA]] gene.

Brunner syndrome is a rare genetic disorder associated with abnormal production of the enzyme monoamine oxidase A (MAOA). It is characterized by lower than normal intelligence, behavioral problems, and a tendency towards violence. The syndrome is named after Hans Brunner, the Dutch human geneticist who first described it.
Symptoms[edit]
The symptoms of Brunner syndrome can vary greatly from person to person. However, common symptoms include:
- Lower than normal intelligence
- Behavioral problems
- Tendency towards violence
- Impulsivity
- Mood swings
- Sleep disturbances
Causes[edit]
Brunner syndrome is caused by mutations in the MAOA gene. This gene provides instructions for making an enzyme called monoamine oxidase A, which is involved in the breakdown of certain chemicals in the brain. Mutations in the MAOA gene lead to reduced activity of this enzyme, which can result in an imbalance of chemicals in the brain and the symptoms of Brunner syndrome.
Diagnosis[edit]
Diagnosis of Brunner syndrome is based on the presence of characteristic symptoms, a detailed patient history, a thorough clinical evaluation, and a variety of specialized tests. Genetic testing can confirm a diagnosis.
Treatment[edit]
There is currently no cure for Brunner syndrome. Treatment is symptomatic and supportive, and may include medications to manage symptoms, behavioral therapy, and educational support.
