Gao et al examined the association of 12 SNPs in the SLC2A9 locus with PD in a case-control study in individuals of European descent, consisting of 788 self-reported cases and 911 controls.20 SNPs were all in linkage disequilibrium (R2 > 0.7), and the study found that for one SNP, the allele associated with lower plasma urate, was nominally associated with a higher risk of PD (95% CI, 1.48 (1.01–2.16); p = 0.04). The gene discussed is SLC2A9; the disease is Parkinson disease.
