TRAF5 eQTLs in brain cortex showed a nominal association with PD risk (P = 0.048, Pfdr = 0.607), while CASP8 showed nominal associations with RBD risk in both brain cortex and whole blood (P = 0.033, Pfdr = 0.607; P = 0.002, Pfdr = 0.102, respectively). The gene discussed is TRAF5; the disease is Parkinson disease.
