We determined the association of the Alu-insertion Yb8NBC36 in the KCNJ6 gene in 200 Parkinson’s Dis­ease (PD) patients and 259 controls from the Bashkor­tostan Republic, matched for age, ethnic origin and area of residence. We found allele *I to be more frequent in PD patients than in controls [p <0.05; odds ratio (OR) = 1.55; 95% confidence interval (95% CI) = 1.19-2.03] and the *I/*I genotype and allele *I to be genetic markers of an increased risk in both PD patients of various ethnic origin (Russians, Tatars and Bashkirs) and in different PD forms and stages.
