Drinking Intensity Can Be Influenced By Specific DNA Variations Of The Serotonin Transporter Gene

The brain’s serotonergic system plays an important role in alcohol preference and consumption. New findings show that specific DNA sequence variations of the serotonin transporter gene can influence drinking intensity among alcohol-dependent individuals. The brain’s serotonergic system plays an important role in alcohol preference and consumption. The serotonin transporter gene (SLC6A4), in particular, may regulate a person’s propensity for severe drinking.
