title: Interleukin-10 promoter polymorphisms in Chinese patients with Parkinson's disease.
abstract: Interleukin-10 (IL-10), an important anti-inflammatory cytokine, may influence the risk for the development of onset of sparadic Parkinson's disease (PD) in the inflammatory process. In this study, two DNA polymorphisms at IL-10 gene promoter (-819 T/C and -592 A/C) were examined in 355 sporadic PD patients and 200 healthy controls in Han Chinese Population. For both polymorphisms, no significant difference in genotype or allele distribution was found between PD patients and the controls. For -819 T/C polymorphisms, there was significant difference in genotype distribution between EOPD (EOPD, <50 years of age) patients and each healthy-matched control subgroup (P=0.011), as well as between female PD patients and each healthy-matched control subgroup (P=0.024), For -592 A/C polymorphisms, there were no significant gender- and age-related differences in genotype distribution between PD patients and the controls subgroup. Results from our study revealed that the IL-10 promoter (-819 and -592) polymorphism is not a risk factor of sporadic Parkinson's disease, but the IL-10 promoter -819 polymorphism is a risk factor of EOPD and female PD patients in Han Chinese population.
