Objective To explore the association between Parkinson' s disease (PD) and the single-nucleotide polymorphism rs2736990 and rs356219 of alpha-synuclein (SNCA) gene.Methods Five hundred and fifteen unrelated patients with sporadic PD and 450 healthy ethnically matched control subjects were consecutively recruited for the study.They were Han population from Jiangsu Province.Patients and normal controls were genotyped for SNCA (rs2736990 and rs356219) variants by ligase detection reaction.Results There was significant difference in the allele frequency(C,T) and genotypes (CC,CT,TT) of patients and controls for rs2736990C >T(67.0% (690/1030),33.0% (340/1030) vs 61.8% (556/900),38.2% (344/900),x2 =5.704,P =0.017 ; 44.7% (230/515),44.7% (230/515),10.7% (55/515) vs 40.0% (180/450),43.60% (196/450),16.4% (74/450),x2 =7.264,P =0.027,respectively) ; The frequencies of the homozygous genotype for this variant were 10.7% (55/515),which were significantly lower than those in controls (16.4% (74/450),X2 =6.61,P =0.010).A statisticall significant was found in the frequencies of the single alleles (A,G) and genotypes (AA,AC,GG) of rs356219 A > G between PD patients and normal group (36.5% (376/1030),63.5% (554/1030) vs 45.2% (407/900),54.8% (493/900),x2 =15.138,P =0.001 ; 13.8% (71/515),45.4% (234/515),40.8% (210/515) vs 22.40% (101/450),45.6% (205/450),32.O% (144/450),x2 =15.144,P <0.01,respectively) ; The frequencies of the homozygous genotype for this variant were 40.80% (210/515),which were significantly higher than those in controls (32.0% (144/450),X2 =14.43,P =0.000).The frequency of the C-G haplotype was significantly higher in PD group compared to healthy controls(P < 0.01 ;odds ratios (OR) =1.439; 95% confidence intervals (95% CI) 1.199-1.727).The CA and TA haplotypes were significantly less frequent in patients than in controls (P =0.000,OR =0.472,95% CI 0.3-0.717 and P =0.019,OR =0.799,95% CI 0.663-0.963,respectively).Conclusions SNCA gene may have an effect on susceptibility to PD in Han population from Jiangsu province,China.rs356219 G allele may have an increased risk of susceptibility to PD,rs2736990 T allele may have an decreased risk of susceptibility to PD.Further studies are needed to replicate the association that we observed.
