Objective:
To investigate whether the angiotensin II type I receptor gene (AGTR1) A1166C polymorphism is associated with a high risk of diabetic nephropathy.
Methods:
The allele frequency and the genotype distribution of the AGTR1 A1166C polymorphism were studied in normal controls (157 cases), simple diabetes (141 cases, duration of diabetes >10 years), and diabetic nephropathy (152 cases) by means of polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).
Results:
Patients with diabetic nephropathy had a higher frequency of C allele of the AGTR1 A1166C polymorphism than that of normal controls and simple diabetes (P<0.05); but there was no significant difference in frequency of C allele between the normal controls and patients with simple diabetes.
Conclusion:
The diabetic patients with AGTR1 C allele may be more susceptible to diabetic nephropathy than diabetic patients with A allele.
