Gene mutation linked to impulsive behaviour with alcohol, study finds

Disruption to gene HTR2B could affect decision-making and self-control and may explain why some people are more prone to impulsive behaviour
A genetic mutation that makes people more impulsive when they consume alcohol may explain why some are more prone to drink driving, impulsive sex and random acts of violence.
The mutation disrupts a gene called HTR2B which the body uses to make serotonin receptors in parts of the brain that have a governing role in decision making and self-control.
