The concentrations of PINK1 in the sera were higher in patients with MS (median, interquartile range 2250, 480-4520 pg/mL), patients with NMOSD (500, 330-710 pg/mL; p < 0.001), MOGAD (340, 270-520 pg/mL; p = 0.011), and controls (500, 330-700 pg/mL; p = 0.02) (Figure 1B). The gene discussed is PINK1; the disease is myeloid sarcoma.
