MANBA and attention deficit-hyperactivity disorder: For ADHD, the expression levels of two genes—MANBA (p = 1.63E-07 in”cerebellar hemisphere”) and LEPRE1 (p = 5.05E−09 in “frontal cortex”)—showed significant association and 18 additional genes showed signs of suggestive association (p < 0.001) (Table S4).
