    Abstract:
    Recent studies suggest that inflammation may play an important role in the pathogenesis of Parkinson's disease (PD). Because the C(-260) --> T polymorphism in the promoter of the CD14 monocyte receptor gene (pCD14) could affect the predisposition to the inflammatory response, we conducted a case-control study to investigate a possible genetic susceptibility of the pCD14 polymorphism in patients with PD. This study included 200 sporadic PD patients and 200 controls, matched by sex and case-control pairs for age at onset in the case. All observed genotype frequencies were in Hardy-Weinberg equilibrium. Results revealed that the CD14-T allele of the pCD14 polymorphism in the female PD patients existed statistically significant difference from that of the female controls (OR = 1.262, P = 0.038), but not for male. Female individuals with homozygote CD14-TT genotype were significantly increased risk of PD by 1.28 time (P = 0.027). Furthermore, a logistic regression analysis confirmed that the homozygote CD14-TT genotype was an independent risk factor for PD (OR = 1.576, P = 0.030). In conclusion, results of this study indicate the pCD14 polymorphism to be a genetic risk factor for PD in females.
