LIS1 heterozygosity is a significant cause of lissencephaly, while overexpression has recently been noted in cases of microcephaly, ventriculomegaly, and dysgenesis of the corpus callosum with normal cortical gyration.

Brain malformations caused by 17p13.3 deletions include lissencephaly with deletions of the larger Miller-Dieker syndrome region or smaller deletions of only PAFAH1B1, white matter changes, and a distinct syndrome due to deletions including YWHAE and CRK but sparing PAFAH1B1.
