Researchers from the National Autonomous University (UNAM) have identified a gene found in the nation´s indigenous population that may explain why so many Mexicans suffer from diabetes.In a new study, researchers say that the gene that regulates insulin and glucose levels in the human body has over generations mutated and is now inherent in the nation´s mestizo population. The mutated gene interferes with the body´s ability to control its insulin and glucose levels.
The study adds that the gene, coupled with a poor diet, "significantly" increases the risk of developing diabetes.
Menjivar Iraheta, who headed the research at UNAM´s faculty of chemistry, said the finding would help identify people who were more likely to develop the disease and aid in prevention.
"By identifying this gene we´ll be able to determine at birth whether someone will be at risk from protracting diabetes and we can then recommend the right type of diet and exercise for them," Iraheta said.
Diabetes affects more than 10 million Mexicans and is the disease with the leading number of deaths in the nation, according to the study.
HIGH PRESENCE
The presence of the gene is much higher in Mexico compared to other countries with high levels of diabetes sufferers such as Japan, Denmark and Spain, the study said. In Mexico, between 15 and 20 percent of diabetics under the age of 35 are mestizo - or of mixed indigenous and European descent - while 13 percent are Teenek Indians and 6 percent are Mazahuas.
