Researchers identified almost two dozen previously unknown genetic variants linked to type 2 diabetes by including participants’ hormone levels in their analysis. Yan V. Sun of Emory University, U.S., and colleagues report these findings in the open-access journal PLOS Genetics<\/a>.<\/p>\n Type 2 diabetes affects an increasing number of people worldwide, and more often affects men than women. The disease is caused by a mix of genetic and lifestyle factors, but little is known about how someone’s environment\u2014both inside and outside the body\u2014interacts with their genes to impact a person’s risk of developing the disease.<\/p>\n In the new study, researchers performed genome-wide interaction studies to investigate whether a person’s hormone<\/a> levels interact with their genetic variants to affect their risk of developing type 2 diabetes.<\/p>\n They grouped males and females independently and considered measurements of three types of sex hormones\u2014total testosterone, bioavailable testosterone and sex-hormone binding globulin. The information came from white European participants in the UK Biobank, which contains biological samples<\/a> and health data<\/a> from half a million people.<\/p>\n The researchers used statistical analyses to identify relevant variants in the genomes of individuals with and without type 2 diabetes. By taking into account hormone levels, the analysis was able to identify 22 spots on the genome that increased a person’s risk for type 2 diabetes. These variants had not been reported previously in the most recent genomic study for type 2 diabetes.<\/p>\n The new study suggests that a person’s hormone levels may be interacting with their genes to increase their odds of having type 2 diabetes. For future studies, the researchers recommended that additional hormone measurements for each participant and more diverse cohorts should be included.<\/p>\n They conclude that this approach, which includes environmental factors in genomic studies, may help us to identify additional disease-related genes and gain a better understanding of the mechanisms behind complex diseases.<\/p>\n The authors add, “We found that sex hormone levels contribute to differences in genetic risk factors for type 2 diabetes in men and women. By analyzing data for men and women separately, we identified new genetic associations with type 2 diabetes<\/a>.”<\/p>\n The lead analyst, Amonae Dabbs-Brown notes, “I actually used to work at the CDC developing methods to measure some of these sex hormones. It’s really exciting to see what happens downstream. Maybe one day I’ll even get to see how these analyses are used in the clinic.”<\/p>\n More information: \t\t\t\t\t\t\t\t\t\t\t\tProvided by \t\t\t\t\t\t\t\t\t\t\t\t\t<\/a><\/p>\n \n Citation: \n This document is subject to copyright.
