MGLL and autosomal dominant cerebellar ataxia: The first studies to determine the status of the endocannabinoid system consisted of analyses of some key endocannabinoid elements (e.g., CB1 receptor, CB2 receptor, fatty acid amide hydrolase (FAAH), monoacylglycerol lipase (MAGL)) in the post-mortem cerebellum of different SCA patients compared to control subjects (Rodríguez-Cueto et al., 2014a,b; see Table 2 for a summary of these endocannabinoid elements in SCA patients).
