Recently, the genes p19 S-phase kinase-associated protein 1A (SKP1), huntingtin interacting protein-2 (UBE2K), aldehyde dehydrogenase family 1 subfamily A1 (ALDH1A1), 19 S proteasomal protein PSMC4, and heat shock 70-kDa protein 8 (HSPA8) have been found to predict the onset and progression of Parkinson's disease (PD).
Stepwise multivariate logistic regression analysis identified five genes as optimal predictors of PD: p19 S-phase kinase-associated protein 1A (odds ratio [OR] 0.73; 95% confidence interval [CI] 0.60-0.90), huntingtin interacting protein-2 (OR 1.32; CI 1.08-1.61), aldehyde dehydrogenase family 1 subfamily A1 (OR 0.86; 95% CI 0.75-0.99), 19 S proteasomal protein PSMC4 (OR 0.73; 95% CI 0.60-0.89) and heat shock 70-kDa protein 8 (OR 1.39; 95% CI 1.14-1.70).
