The data were analyzed to determine associations between mitophagy biomarkers (PINK1, BNIP3L, TFEB), AD biomarkers (Aβ42/40, Aβ42, p-MAPT/tau [181], t-MAPT/tau), and markers of neurodegeneration and synaptic dysfunction (NEFL and NRGN, respectively). The gene discussed is NRGN; the disease is Alzheimer disease.
