Can Genes Influence Violent Behavior?
A very interesting study was released recently about violent crimes and the way that an individual’s genetic makeup could play a role in these violent acts. Researchers found that there are two key genes that seem to dictate, at least in part, how violent crimes come about. The researchers said these two genes could be blamed for 5-10 percent of violent crimes in Finland.
The two genes are called MAOA and CDH13, and they are linked to dopamine regulation and impulse control, respectively. Any genetic mutations dealing with these genes could cause someone to be more prone to committing violent acts. Indeed, the study says that variants of MAOA and CDH13 were linked with “extremely violent behavior.” Given what these genes deal with, this should come as no surprise.
Researchers were quick to note, though, that violent acts and the crimes related to these acts are complex. There are many factors that go into someone exhibiting violent behavior, and their are many factors that go into the actual situation where a violent act is committed.
Still, this is an interesting bit of information that helps us better understand what causes some people to act out in a more violent manner than others.
Violent crimes often carry extensive consequences, and the obvious gruesome connotation that a violent crime has can cause the person being accused of the crime to be put in a tough situation. Anyone dealing with a charge relating to a violent offense needs legal representation to protect their rights.
