We found in our recent study [240] that the rs6119534-T allele of the GGT7 gene is strongly associated with a decreased risk of T2D, especially among individuals without T2D-related risk factors such as physical inactivity, smoking, stress, insufficient consumption of fresh fruits/vegetables and proteins, excessive consumption of carbohydrates, and low-fiber foods. The gene discussed is GGT7; the disease is type 2 diabetes mellitus.
