PAFAH1B1 and Lissencephaly: Many microtubule-associated genes are linked to ID and to other NDDs in which ID appears as a prominent and recurrent phenotype: ADNP mutations are associated with ASD; ASPM, MCPH1, STIL, CDK5RAP2, CENPJ, PRUNE1, and KIF20 mutations are associated with microcephaly; TUBB2B mutations are associated with polymicrogyria; LIS1, DCX, and TUBA1A are linked to lissencephaly [288].
