Abstract

Aim: To investigate the association of LEPR polymorphisms and plasma leptin and soluble leptin receptor (sOB-R) levels with polycystic ovary syndrome (PCOS) in Chinese women.

Patients & methods: LEPR Lys109Arg (rs1137100) and Gln223Arg (rs1137101) polymorphisms of PCOS patients and the controls were genotyped. Plasma leptin and sOB-R levels of two groups were measured.

Results: The genotypic distributions of Lys109Arg (rs1137100) differed between the PCOS and control groups. Plasma sOB-R levels increased significantly in PCOS patients and were associated with PCOS independent of BMI. Furthermore, luteinizing hormone, triglyceride and fasting blood glucose correlated significantly to PCOS patients' sOB-R levels.

Conclusion: LEPR Lys109Arg (rs1137100) was associated with PCOS susceptibility and genotype AA was deduced to be a protective factor for PCOS; sOB-R levels might be recognized as a new indicator for the severity of PCOS.
