We found that the ROS levels were significantly increased in PBLs from both sPD patients and those with the PARK2 C441R mutation compared to healthy controls (control 100 ± 0, sPD 275.53 ± 79.11, and C441R 340 ± 99.67; Figures 1(a) and 1(b)). The gene discussed is PRKN; the disease is Platelet storage pool disease.
