A brain disorder caused by biallelic variants in NDE1 that is characterized by extreme microcephaly (typically head circumference of more than 10 standard deviations (SD) below the mean), profound motor and intellectual disability, spasticity, and incomplete cerebral formation. Radiologic studies demonstrate overt microcephaly with cortical dysgenesis ranging from simplification to pachygyria/lissencephaly to hydranencephaly. Agenesis of the corpus callosum as well as hypoplasia of the brainstem and cerebellum are typically present.
Biomarker and diagnostic research for microcephaly with lissencephaly and/or hydranencephaly has been reported in the published literature.
No clinical trials have been registered for microcephaly with lissencephaly and/or hydranencephaly.
55 publications have been identified in PubMed for microcephaly with lissencephaly and/or hydranencephaly. Research spans Case Report / Case Series (38%), Basic Science / Preclinical (20%), and Epidemiology / Natural History (16%).
