DAB1 and cerebellar ataxia: In addition, the identified gene DAB1 is in the KEGG pathway of a group of progressive neurodegenerative diseases “Spinocerebellar ataxia” (hsa05017), which are usually due to the dysfunction of the cerebellum (Paulson 2009; Matilla-Dueñas et al., 2010), and it has been reported that cerebellar damage is associated with an increased risk of the ASD (Becker et al., 2013; D'Mello et al., 2015).
