We also characterized a severe dysplasia of CPNs in Mllt11 cKO mutant neonatal brains; a phenotype found in severe neurodevelopmental disorders such as ASD and Fragile X-associated tremor ataxia syndrome with which Mllt11 dysregulation has been associated (Xu et al., 2016; Drozd et al., 2019). This evidence concerns the gene MLLT11 and fragile X-associated tremor/ataxia syndrome.
