Abstract:
Objective To investigate the association of α-synaptophysin A53T gene polymorphism with parkinson's disease(PD) in Chinese people.Methods The conventional polymerase chain reaction was used to detect the α-synaptophysin A53T gene polymorphism in 224 sporadic PD patients(PD group)and 154 healthy individuals(control group).According to the Hoehn-Yahr(H-Y) classification standard, PD patients were divided into H-Y ≥ 3 group(n=172) and H-Y ≤ 2.5 group(n=52).Each genotype and alleles frequencies as well as the A53T gene expression and their relation to the severity of parkinson's disease were analyzed with Chi-square test of SPSS19.0.Results The frequency of the A53T genotype of A/A were 40(17.9%) and 10(6.5%) (x2 =10.267, P=0.001, OR=3.13,95% CI =1.514-6.473) in the PD group and control group, respectively.The frequency of the allele A was 160(35.7%) and 70(22.7%) (x2 =14.543, P=0.000, OR=1.889,95% CI =1.359-2.625) in the PD group and control group,respectively.The frequency of the A53T genotype of A/A was 30(17.4%) and l0 (19.2%) in the H-Y ≥ 3 group and H-Y ≤ 2.5 group, respectively, with significant difference (P=0.003,0.007) as compared to the control group.The frequency of the allele A was 122(35.5%) and 38(36.5%) in the the H-Y ≥ 3 group and H-Y ≤ 2.5 group,respectively, with significant difference (P=0.000,0.006) as compared to the control group.There was no statistically significant difference of the A53T genotype of A/A and the allele A between the H-Y≥3 group and H-Y≤2.5 group (P=0.768,0.841).Conclusion The A53T gene polymorphism is the risk factor of Parkinson's disease in Chinese people, but it isn't correlated to stage of sporadic parkinson' s disease.
