These genes include MAPT, KANSL1, PLEKHM1, STX6, MOBP, EIF2AK3, SLC01 A2, DUSP10, APOE, RUNX2, TRIM11, NFASC/CNTN2 and LRRK2. The physiologic function of these genes is described and their potential role in the etiology of PSP is discussed. This evidence concerns the gene MAPT and supranuclear palsy, progressive, 1.
