Objective: Although the role of the leptin receptor (LEPR) in obesity is well recognized. its role in insulin sensitivity remains unknown. Design: This was a cross- sectional study to investigate the impact of the Q223R polymorphism of the LEPR gene on insulin sensitivity. Methods: Sixty-seven glucose-tolerant Caucasians were enrolled. The insulin sensitivity index and glucose clearance were measured using a hyperglycemic clamp. Genomic DNA was extracted for genotyping. Results: We identified 20 QQ, 31 OR. and 16 RR subjects. The three genotypic groups were similar in age. gender distribution, body mass index. waist-hip ratio, and blood pressure, but differed in the insulin sensitivity index (P = 0.0180) and in glucose clearance (P = 0.0220). Multivariate analyses showed that the Q223R polymorphism was independently associated with the insulin sensitivity index (P = 0.031.7) and glucose clearance (P = 0.0436). A trend of increasing low density lipoprotein cholesterol concentration was also observed (11= 0.0447). Conclusion: Cafe have reported the first association of the Q223R polymorphism of the LEPR gene with insulin resistance.
