DAB1 and spinocerebellar ataxia type 37: Repeated ATTTC expansion of the DAB1 gene leads to overexpression of DAB1 and induces an RNA switch, causing upregulation of the reelin-DAB1 and PI3K/AKT signaling pathways in the cerebellum of patients with SCA37, leading to cerebellar neuronal degeneration (Corral-Juan et al., 2018).
