Background: The transcription factor 7-like 2 gene (TCF7L2) is the strongest locus associated by the variant rs7903146 with type 2 diabetes (T2D) identified to date. Whether diet/lifestyle intervention modifies genetic effect of TCF7L2 variant on glucose homeostasis and adiposity is still controversial. Objective: To quantify the modification effects of the diet/lifestyle interventions on genetic association of TCF7L2 variant rs7903146 with glycemic control and adiposity changes in randomized controlled trials (RCTs). Design A large collaborative analysis of individual-participant data from seven RCTs. Setting RCTs conducted in adults reporting changes in glycemic traits, body weight, or waist circumference by TCF7L2 rs7903146 after dietary/lifestyle-based interventions. Gene-treatment interaction models were fitted to individual participant data from all studies, using allele dose coding for genetic effects and a common set of covariates. Results: We included seven eligible RCTs for the joint analysis (n=4,114 participants). Overall, a significant interaction between TCF7L2 rs7903146 and diet/lifestyle interventions on decrease in fasting glucose was observed. Compared with control, diet/lifestyle interventions reduced fasting glucose by -0.17 (95% CI, -0.32 to -0.02) mmol/L (test for heterogeneity: I2=45.1%, p |
