However, out of the FTLD-C9orf72 group, three had FTD-MND; one had mild dystrophy in FG and TG but moderate dystrophy in FW and TW, the second had severe dystrophy throughout the frontal lobe but moderate dystrophy in the temporal lobe, and the third had moderate dystrophy in FG but severe dystrophy in all other regions. The gene discussed is C9orf72; the disease is mild neurocognitive disorder.
