These include circRNAs from genes associated with neurodevelopmental disorders and Alzheimer’s disease, e.g., circBrwd1 and circFoxp1 (Bacon et al., 2015; Quan et al., 2020); involved in neuronal development and regeneration, e.g., circMap1a (Nunez and Fischer, 1997) and, encoding members of the Plasticity Related Genes (PRGs) and membrane-associated guanylate kinases (MAGUKs) families, e.g., circMagi1 and circLppr4, respectively, which control synaptic development and are linked to psychiatric disorders (Ito et al., 2012; Yu et al., 2015). This evidence concerns the gene GART and psychiatric disorder.
