In the same year, another study focused on the comparison of RELN and Bcl-2 levels in homogenates of cerebellar tissue obtained from 5 subjects with autism and 8 controls, which showed a significant decrease of Reelin (43–44%) and Bcl-2 (34–51%) levels in comparison to healthy controls (Fatemi et al., 2001). This evidence concerns the gene RELN and autism.
