Furthermore, the caudate nucleus, pallidum, putamen, and PD showed enriched gene expression for histocompatibility minor 13 (HM13), inhibitor of DNA binding 1 (ID1), cytochrome c oxidase subunit 4I2 (COX4I2), BCL2 like 1 (BCL2L1), TPX2 microtubule nucleation factor (TPX2), myosin light chain kinase 2 (MYLK2), forkhead box S1 (FOXS1), dual specificity phosphatase 15 (DUSP15), and COMM domain containing 7 (COMMD7). Here, DUSP15 is linked to Parkinson disease.
