Researchers at the Monterrey Institute of Technology and Higher Education (ITESM) created a genetic test that allows the detection of type 2 diabetes and obesity through saliva using a non-invasive device.
XplorADN, name of the test, identifies variations in the genetic material by detecting small changes called polymorphisms that can indicate unique characteristics of each person’s DNA.
Gerardo Velasco Gutiérrez, one of the ITESM researchers, explained that the test is sent to the patient through an online page. The user must follow the instructions to provide two milliliters of saliva which has to be send to the laboratory.
“Once it reaches us, we submit it to a simple process of DNA analysis and it shows the results of prevalence of obesity and/or diabetes.”
In turn, María del Carmen Velasco Rendón, part of the scientific team at the Department of Bioengineering, indicated that when the results of XplorADN are obtained, the patient is sent a report with general recommendations on diet, physical activity and more. For example, if there is a predisposition to type 2 diabetes, the appearance of the disease can be delayed for up to 10 years by making a lifestyle change.
Due to technological development, the five researchers created a preventive medicine genetics company of the same name of their diagnostic tool, to improve the quality of life of people. Dr. Velasco Rendón explained that XplorADN is a 100% Mexican product.
Dr. Velasco Gutiérrez, president of the company, said they are in talks with a pediatrics association to look for a method that allows to do the test in newborns and to know if they will suffer from obesity and/or diabetes.
“This is only the first stage, in the future cancer, heart disease or other types of conditions can be detected under the same principle,” said Velasco Gutiérrez.
