It’s considered the first, large-scale analysis of its kind,  and the study could change the way health care is delivered to Mexican-Americans. It helps drive forward the move toward personalized medicine.

Burchard described that because of “historical factors, geographical factors, linguistic factors,” the researchers identified that indigenous populations in Mexico are genetically distinct. The genetic ancestry mirrors the geography of Mexico.” Continue reading
