Although NDEL1 variants have never been reported to cause lissencephaly in humans, previous studies have strongly linked NDEL1 to other lissencephaly genes such as LIS1 [17, 27, 81] and DYNC1H1 [32, 51], making NDEL1 a good candidate gene for lissencephaly. The gene discussed is DYNC1H1; the disease is lissencephaly spectrum disorders.
