Fig. 6: Gene enrichment analysis of hot genes associated with ADHD.
From: Genetic variations influence brain changes in patients with attention-deficit hyperactivity disorder

Gene expression heatmaps constructed with GTEX v8 (54 tissue types). The heatmap indicates the significance of expressed gene modules related to brain regions. Blue to red reflects a significant association of the gene with brian regions as determined by a standardized z score. The gene expression heatmap showing higher relative expression levels of MAOB, SNAP25, COMT, MAOA, ADRA2C, DRD1, DRD2, HTR2C, CHRNA4, and TH in different brain sites suggest that these genes may be linked with brain areas and are considered as a risk factor for ADHD.
