DNAH8 and dementia: Of the eight enriched gene sets in the non-dementia group, four were closely related to neurological and/or HIV disease: dendrite (GO: 0030425) (Figure 2A), ATPase activity coupled to transmembrane movement of ions (GO:0042625) (Figure 2C), ATPase activity coupled to transmembrane movement of ions phosphorylative mechanism (GO:0015662), and cytoskeleton dependent intracellular transport (GO:0030705) (Figure 2E).
