CACNA2D3 and epilepsy: Gene set enrichment analysis on striatum-specific differentiated genes revealed that most downregulated genes are involved in calcium transport or calcium transmembrane transport (Supplementary Fig. 3d, k) or associated with striatal degeneration, mental retardation, dyskinesia, ataxia, and epilepsy (such as Camk2b, Pde10a, Kcnab1, Tomm70a, and Cacna2d3; Supplementary Data 1).
