SEPTIN5 and Alzheimer disease: Among the 809 genes, we found multiple neuronal genes positively correlating with MAPT across most cancer types (e.g., BSN, SORCS1, CAMK2B, SNAP25, SEPT5, UNC13A, UCHL1, NSF, synaptophysins SYP and SYPL2, and synaptotagmins SYT4, SYT12 and SYT14), some of which have been linked to AD.
