Researchers make breakthrough findings on genetic influences in alcohol use

The gene is known as autism susceptibility candidate 2, or AUTS2, and has previously been linked to autism and attention deficit hyperactivity disorder, according to Australian Associated Press (AAP).

"Our research has found that a small genetic change can lead to increased consumption of alcohol," Professor Nick Martin from QIMR' s Genetic Epidemiology Laboratory said in a statement.

"The gene is most active in parts of the brain associated with neuropsychological reward mechanisms, suggesting that it might play a part in the positive feelings that people have when they drink alcohol," Martin said.

The researchers hope the discovery may lead to a better understanding of genetic mechanisms influencing alcohol drinking behavior within the general population.

"Although many of the influences on alcohol drinking are non- genetic (reflecting societal, lifestyle, and behavioral influences) , there is also an important genetic component," Martin said.

The study of over 47,000 people found that there were two types of the AUTS2 gene, one of them three times more common than the other. Kazinform cites Xinhua. See www.xinhuanet.com for full version
