A common genetic variant influences individual responses and adaptation to pain and other stressful stimuli and may underlie vulnerability to many psychiatric and other complex diseases, reports David Goldman, M.D., Chief, Laboratory of Neurogenetics, National Institute on Alcohol Abuse and Alcoholism, and colleagues at NIAAA and the University of Michigan. COMT val158met Genotype Affects m-Opioid Neurotransmitter Responses to a Pain Stressor appears in the February 21 issue of Science (299:1240, 2003).
"Emotional response to stress contributes in many drinkers to the development of alcoholism," said George Kunos, M.D., Ph.D., Scientific Director, Division of Intramural Clinical and Biological Research, NIAAA. "Dr. Goldman and his colleagues have uncovered a genetic explanation for why some individuals and groups may be especially susceptible to consuming alcohol and to increasing their consumption in response to stress."
