OBJECTIVE: To investigate the association between the C609T polymorphism of NADP (H): quinoneoxidoreductase 1 (NQ01) gene and decreased cognitive function and sporadic Alzheimer's disease (AD) in a community cohort. METHODS: Polymerase chain reaction (PCR), denaturing high performance liquid chromatography (DHPLC) and sequencing were used to determine the genotype of NQ01 in 110 subjects without cognitive dysfunction, 21 with cognitive dysfunction, and 65 AD patients from a community cohort. RESULTS: Significantly different distributions of C/T and T/T genotypes were found between MMSE normal and abnormal subjects (OR=2.8, 95%CI 0.96-8.18, P=0.024), and between AD patients and healthy controls (OR=3.27, 95% CI 1.54-6.94, P=0.001), respectively. The frequencies of T allele of NQ01 C609T were significantly higher in MMSE abnormal subjects and AD patients (P=0.034 and 0.005) as compared to normal controls. CONCLUSION: The C609T polymorphism of NQ01 gene may be a genetic risk factor for cognitive dysfunction and sporadic AD in Chinese population.
