Gene variations may lead to alcohol abuse among teenagers, researchers say

By Staff Writer

A new study suggests that there may be a genetic explanation as to why some problem teens regularly indulge in binge drinking.

Researchers from Radboud University in the Netherlands have found that teens who frequently consume large amounts of alcohol may be attempting to suppress negative emotions from two different genes. The study will appear in the April 2011 edition of the journal Alcoholism: Clinical and Experimental Research.

Researchers conducted DNA analysis in 282 Dutch teens, and they found genetic variations in DRD2 - a dopamine receptor gene - and SLC6A4 - a serotonin transporter gene. Both play a role in the human emotional state.

The study's authors concluded that more research should be conducted in order to confirm their results. They are hopeful the association between genetic variants and teen alcohol use may help medical professionals treat their unhealthy habits.

Some adolescents who abuse alcohol lack discipline in their lives, which can also contribute to their addictive tendencies. Boarding schools may offer the structure and support needed to provide help for troubled teens.
