Single diabetes gene mutation found in Mexican population

Genetic sequencing of 8,000 Mexicans revealed a single gene that is present in mestizos (mixed race) and indigenous people of Mexico, according to a new study.

The research, which was published in theJournal of the American Medical Association, found that this gene - SLC16A11 - can make a person five times more likely to develop the disease compared to other populations.

Karol Estrada, scientist from the Broad Institute in Boston, directed the genetic sequencing study using computational analysis.

Locating the gene required a long process of gathering genetic samples from people in Mexico City and Los Angeles.

A new way to spot diabetes?

According to Estrada, the findings show that a genetic DNA test could determine what type of diabetes a person has in minutes.

For the second part of the study, researchers are working on developing a genetic diagnostic tool that would cost less than 100 pesos.

"It enables us to do the work knowing that it is a single gene variant for the Mexican population and not having to test for many other genes, "Dr. Estrada said in a news release.
