Background: Type 2 diabetes mellitus is a prevalent hereditary condition that has multiple genetic risk factors as well as environmental influences. Aim: The Work aimed to find if there is an association between the presence of Single Nucleotide Polymorphism of the Adiponectin gene & its association with type II diabetes in Egyptian patients. Material & Techniques: This case-control research had been conducted at Molecular Biology and Biochemistry, Genetic Engineering & biotechnology institute, university of Sadat city. This research had been conducted on eighty patients; separated into 2 groups diabetic group and the control group. Results: significant reduction in adiponectin level in type II diabetes studied cases compared to normal control subjects (p <0.001). GG genotype is significantly more predominant in type 2 diabetes (54%) while the GT genotype is more predominant in control (60%) (p-value =0.04)., while no variation in allele distribution among both groups (p value=0.6). Conclusion: In studied cases with type 2 diabetes, there was a significant reduction in adiponectin levels in type II diabetes patients. GG genotype is significantly more predominant in type 2 diabetes. The genotype GG significantly rises the risk of occurrence of type 2 diabetes.
