PG - 172-7 LID - 10.1177/1470320313478286 [doi] AB - INTRODUCTION: Bahrain has a high prevalence of type 2 diabetes mellitus (T2DM). Previously, Angiotensin-converting enzyme (ACE) insertion/deletion (I/D) polymorphism was found to be associated with T2DM in Bahrainis. The relationship between the disease progression in Bahraini T2DM population and the genetic polymorphism of methylene-tetrahydrofolate-reductase (MTHFR) C677T is still under investigation. AIM: The current study investigated the distribution of MTHFR C677T gene polymorphism among Bahraini T2DM patients and examined the interaction between ACE I/D and MTHFR C677T polymorphisms on the risk of developing T2DM and its long-term complications. MATERIALS AND METHODS: Polymerase chain reaction (PCR) and PCR-restriction fragment length polymorphism (RFLP) were used to test for the presence of ACE I/D and MTHFR C677T polymorphisms in 171 patients with T2DM compared to 188 healthy (non-diabetic) age-matched control subjects from Bahrain. RESULTS: The incidence of the DD genotype and D allele of the ACE gene was high among Bahraini T2DM patients. MTHFR allele and genotype frequencies did not differ between patients and controls. No significant relationship was identified between the combinations of ACE I/D and MTHFR C677T polymorphisms with T2DM. CONCLUSIONS: The results clearly showed an association of the ACE I/D polymorphism with the progression of T2DM, but when it interacts with MTHFR polymorphism no influence was detected on the increased risk of T2DM.
