PINK1 and myeloid sarcoma: The concentrations of PINK1 in the CSF were higher in patients with MS (median: 220, interquartile range: 120-310 pg/mL) than in patients with NMOSD (150, 70-190 pg/mL; p = 0.004), MOGAD (110, 20-140 pg/mL; p = 0.008), and controls (130, 90-180 pg/mL; p = 0.021) (Figure 1A).
