Context: Obesity has been strongly associated with risks and is a common factor in the risk of postmenopausal women with breast cancer (BC). Various single-nucleotide polymorphisms have been identified in the adiponectin gene. Aims: We aimed in this study to access the diagnostic value of adiponectin gene polymorphism rs 1501299 (G267T) in BC and its association with serum adiponectin level in obese and overweight postmenopausal BC female patients. Settings and Design: This study was conducted on 90 BC patients divided into two groups according to body mass index (BMI), and 60 apparently healthy females as a control group with matched BMI. Both groups were with BMI >25 (obese or overweight). Subjects and Methods: All participants were subjected to laboratory investigations (CA 15–3, serum adiponectin) and molecular study of adiponectin gene rs 1501299 (G276T) by polymerase chain reaction-restriction fragment length polymorphism technique. Results: A statistically significant difference was observed in the polymorphic genotypes (GT and TT) compared to (GG) wild genotype when compared BC patients to control group (P = 0.001). Also on measuring the risk estimate, a significant difference (odd's ratio was 3.76, 95% confidence interval was 1.68–8.4, P = 0.001). While no statistical significant difference in genotype frequency was found between the obese and overweight patients (P > 0.05). Median serum adiponectin level was decreased in BC patients compared to the control group (8.9 vs. 14.6 with P = 0.004). Conclusions: This study supported the association between adiponectin gene polymorphism, serum level, and BC risk among a group of obese and overweight postmenopausal Egyptian patients.
