Besides, we also highlight other genes with high colocalization scores in different tissues: the GIGYF2 gene, significantly associated with ADHD across the lifespan [63], which contributes to the TRScol from both cortex and frontal cortex, the SLC25A22 gene, which encodes a glutamate transporter with strong expression in the developing brain, that adds important weight to the TRScol from caudate basal ganglia and frontal cortex, and CKS2, a cyclin-dependent kinase involved in the control neuronal differentiation [64], which contributes to the TRScol from the amygdala. This evidence concerns the gene SLC25A22 and attention deficit-hyperactivity disorder.
