Consistently, Parkinson’s biomarkers—including membrane palmitoylated protein 1 (MPP1), solute carrier family 4, anion exchanger, member 1 (SLC4A1), erythrocyte membrane protein band 4.2 (EPB42), Selenium-binding protein 1 (SELENBP1), Glycophorin B (GYPB), α-Hemoglobin Stabilizing Protein (AHSP), hemoglobin-delta (HBD), α-synuclein (SNCA) and ferrochelatase (FECH)—were reduced in l-ANK1 compared with that in h-ANK1 (Figure 3B). This evidence concerns the gene HBD and Parkinson disease.
