What does the MAOA gene do?
The MAOA gene provides instructions for making an enzyme called monoamine oxidase A. This enzyme is part of a family of enzymes that break down molecules called monoamines through a chemical reaction known as oxidation.
What does reduced MAOA activity mean?
People with the low-activity form (MAOA-L) produce less of the enzyme, while the high-activity form (MAOA-H) produces more of the enzyme. Several studies have found a correlation between the low-activity form of MAOA and aggression in observational and survey-based studies.
Does everyone have MAOA gene?
While almost all humans have a functional MAO-A gene, MAO-A deficiency has been seen in at least 5 families with Brunner syndrome. Given that MAO-A degrades amine neurotransmitters, gene variants could affect a person’s personality or behaviour.
How does the MAOA gene influence Behaviour?
The MAOA gene –located in the X chromosome- is also known as the warrior gene, since abnormal versions of the gene often result in aggressive behaviors. Several animal models in which the function of MAO-A is defective display excessive levels of serotonin, dopamine, and norepinephrine (noradrenaline) in the brain.
Can females have Brunner syndrome?
Similar episodes can occur in female family members of males with monoamine oxidase A deficiency, although females do not experience other signs or symptoms of the condition.In some cases, certain foods, such as cheese, appear to worsen symptoms of monoamine oxidase A deficiency.
What are the MAOA and CDH13 genes?
According to the Genetics Home Reference, MAOA is an enzyme that breaks down molecules called monoamines. As for CDH13, according to the Genetic Literacy Project, it helps signal between cells and has been linked to ADHD, schizophrenia, and bipolar disorder.
