Genetic variation alters response to common anti-clotting drug
Millions of people take the anticoagulant drug warfarin to prevent harmful clotting after a heart attack, stroke, or major surgery. But the proper dose of warfarin can vary greatly and can be hard to predict. Some of this variability may boil down to a recently identified gene involved in blood clotting, according to a new study by researchers at the University of Washington in Seattle and Washington University in St. Louis.
