Those traits and their associated genes include: neurodegenerative diseases (SPPL2C, NSF, MAPT, KANSL1, CRHR1), neuropsychiatric disorders (KANSL1, FOXO3, CRHR1), neuroticism (NSF, MAPT, KANSL1, FOXO3, CRHR1), intellectual performance (NSF, FOXO3), reaction time (NSF, MAPT, LRRC37A2, FOXO3, ARL17A), cognitive function (MAPT, LRRC37A2, KANSL1, FOXO3, CRHR1, ARL17A), educational attainment (MAPT, FOXO3, CRHR1) and mathematical ability (FOXO3, CRHR1). The gene discussed is ARL17A; the disease is neurodegenerative disease.
