Rats offer clues to biology of alcoholism | Science News

Alcoholism may stem from using genes incorrectly, a study of hard-drinking rats suggests.

Rats bred either to drink heavily or to shun alcohol have revealed 930 genes linked to a preference for drinking alcohol, researchers in Indiana report August 4 in PLOS Genetics.

Human genetic studies have not found most of the genetic variants that put people at risk for alcoholism, says Michael Miles, a neurogenomicist at Virginia Commonwealth University in Richmond.
