Mexican researchers examined the polymorphisms of three enzymes -- alcohol dehydrogenase (ADH1B), aldehyde dehydrogenase (ALDH2) and cytochrome P4502E1 (CYP2E1) -- in the Mestizo and Huichol groups.
The Huichols, an indigenous group, had the highest CYP2E1*c2 allele frequency documented in the world.
This high frequency, in conjunction with the absence of protective ADH1B and ALDH2 polymorphisms, may place the Huichols at particularly high genetic risk for alcoholism and alcoholic liver disease.

As curious as we are about our ancestors, for practical purposes, we need to think about the ancestry of our genes, according to Cecil Lewis, assistant professor of anthropology at the University of Oklahoma. Lewis says our genetic ancestry influences the genetic traits that predispose us to risk or resistance to disease.

The lack of federal regulation in instances of DNA use will be addressed in the Policy Forum section in the July 3 issue of Science by Sandra Soo-Jin Lee, Ph.D., of the Stanford Center for Biomedical Ethics, and colleagues from four other universities. The need for a clear set of rules governing genetic ancestry testing is becoming more urgent, Lee said, given the proliferation of private corporations that promise consumers insight into their genetic origins.
