	rs9722	rs2239574	rs881827	rs9984765	rs1051169
p-Valuea allele	*4.1 × 10 −6	0.448	0.043	0.007	0.028
p-Valuea genotype	*5.0 × 10 −5	0.233	0.131	0.018	0.049

ORc	2.9 (1.8–4.7)	1.1 (0.8–1.6)	1.4 (1.0–2.0)	1.6 (1.1–2.1)	1.4 (1.0–1.9)

^aEarly onset PD (≤50 years) compared to late onset PD (> 50 years). ^bEarly onset PD compared to controls. ^cOR (95% confidence interval) for early onset PD compared to controls. Significant (p < 0.05) results are shown in bold. With Bonferroni correction for multiple testing (analyses of 5 SNPs and 3 comparisons; controls versus all PD patients, controls versus early onset PD and early onset versus late onset PD) significant (p < 0.0033) results are shown by *. P-values were calculated from Chis-square test and ORs were calculated using logistic regression
