Scientists believe the gene-RASGRF2-is one of many genes suggested to have a link to drinking problems (PNAS journal reports)

The gene boosts levels of a happy brain chemical triggered by alcohol-dopamine.

SAMPLE/RESEARCH METHOD: Brain scans of 663 teenage for dopamine levels against gene-to find causation or correlation

RESULTS: The boys who showed a version of the gene, had heightened dopamine responses in tests.

(lead researcher Prof Gunter Schumann said ""We found that the RASGRF-2 gene plays a crucial role in controlling how alcohol stimulates the brain to release dopamine, and hence trigger the feeling of reward")
