We obtained 11 potential candidates (Table 1): LSMEM1, KCNH4, RNF152, CD300LB, AIG1, APOL1, ABCD2, CELSR2, LMO7, ABCC3 and FFAR3. Five (LSMEM1, AIG1, APOL1, ABCD2, and CELSR2) were upregulated in PD, while the remaining genes were downregulated in PD. This evidence concerns the gene ABCD2 and Parkinson disease.
