Introduction: It has been suggested that Lin-28A and the let-7 microRNA family (Lin-28/let-7 axis) play a critical role in the control of glucose metabolism, insulin sensitivity and resistance to diabetes.

Aim: This case-control study aimed at evaluating the association between Lin-28 rs3811464 polymorphism and the susceptibility to Type 2 Diabetes (T2D) in a sample of Iranian population.

Materials and Methods: This study involved 172 T2D patients and 160 non-diabetic age and gender-matched controls. Lin 28A rs3811464 genotypes were determined by Polymerase Chain Reaction–Restriction Fragment Length Polymorphism (PCR-RFLP) technique.

Results: The results showed that the frequency of the AA genotype was significantly higher in control subjects than in diabetic patients (13.12% vs. 4.65%). In addition, binary logistic regression analysis revealed that rs3811464-AA genotype was significantly associated to T2D after adjustment for BMI, age and lipid profiles. Indeed, subjects with AA genotype were less likely to develop T2D than GG and AG subjects (OR of 0.26, 95% CI 0.10-0.66, p=0.005).

Conclusion: The findings of our study suggest that the Lin 28A rs3811464 is associated with type 2 diabetes susceptibility and subjects with AA genotypes were less likely to develop T2D diabetes.
