Does the MAOA gene make you violent?
The low activity form of the MAOA gene (MAOA-L) has been linked to increased levels of aggression and violence.
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.
How does the MAOA gene cause aggression?
Monoamine oxidase (MAO-A) is an enzyme that functions inactivating neurotransmitter amines such as dopamine and serotonin in the brain. In the absence of sufficient levels of MAO, these neurotransmitters accumulate in neurons, which have been correlated with extreme aggressive behaviors.
Is the warrior gene real?
Monoamine oxidase A gene (MAOA) has earned the nickname “warrior gene” because it has been linked to aggression in observational and survey-based studies. However, no controlled experimental studies have tested whether the warrior gene actually drives behavioral manifestations of these tendencies.
Is there a serial killer gene?
Genetic susceptibility may also lead to mitigation of responsibility in convicts during trials of offenses, leading to reduced punishments. MAOA and CHD13 are sometimes called “serial killer genes.” If we proceed to label people as “serial killer gene” carriers we risk stigmatization at unprecedented levels.
What is the killer gene called?
The genes mentioned on Riverdale are MAOA and CDH13, which are also known as the “Warrior Gene.” In the ’90s, there was research done on the deceased bodies of serial killers to see if there was something in their DNA that made them more likely to kill.
What’s the serial killer gene?
Monoamine oxidase A, also known as MAO-A, is an enzyme that in humans is encoded by the MAOA gene….Monoamine oxidase A.

What is the serial killer gene called?
The idea that serial killers could pass down a gene to their offspring that makes them more likely to become killers themselves is more than terrifying. The genes mentioned on Riverdale are MAOA and CDH13, which are also known as the “Warrior Gene.”
Is MAOA a serial killer gene?
Is the MAOA gene the serial killer gene?
The idea that serial killers could pass down a gene to their offspring that makes them more likely to become killers themselves is more than terrifying. MAOA was believed to be the gene that caused this, but it’s actually a mutation of it, MAOA-L that is linked to dangerous behavior.
What is Mtrr A66G?
The methionine synthase reductase (MTRR) A66G polymorphism is a novel genetic determinant of plasma homocysteine concentrations. Atherosclerosis.
What is Brunner syndrome?
Brunner syndrome is a recessive X-linked disorder characterized by impulsive aggressiveness and mild mental retardation associated with MAOA deficiency (Brunner et al., 1993). [ from OMIM]
Which is part of the X chromosome produces MAOA?
The so-called warrior gene comprises particular variations in the X chromosome gene that produces monoamine oxidase A (MAOA), an enzyme that affects the neurotransmitters dopamine, norepinephrine, and serotonin.
Is the MAOA-L gene linked to violent behavior?
A particularly strong connection has been noted among abuse in childhood, MAOA-L gene variants, and violent behavior in adulthood. A recent review declared that several studies have shown that MAOA-L men previously exposed to early life abuse engaged in significantly higher levels of violent behavior than men with high levels of MAOA.
How are the MAOA and CDH13 genes related?
It showed that Finnish criminals convicted of several violent crimes frequently possessed either MAOA-L or a mutant version of another gene, CDH13, while the nonviolent controls did not. Find details in John Gever’s piece at MedPage Today. CDH13 is involved in signaling between cells.
How did MAOA get the name warrior gene?
It has been a media favorite ever since, acquiring the nickname “warrior gene” in 2004 as a result of an article in Science, of all places. This I learned from John Horgan’s fine rant about the exploitation of MAOA genetics at Scientific American, which describes weaknesses in the research.
