Marchman Act Blog: Low Alcohol Tolerance Linked to Gene
Researchers say they've identified a gene that makes some people more sensitive to the effects of alcohol, the BBC News reported Oct. 19.
University of North Carolina investigators conducted a genome analysis of 200 sibling pairs who had one parent with alcohol dependence but no alcohol problems themselves. Participants were then given the equivalent of three alcoholic drinks and asked to describe the effects. Their descriptions were compared with their genetic test results.
