Isolated lissencephaly type 1 without known genetic defects – http://id.who.int/icd/entity/80358651

Isolated lissencephaly type 1 without known genetic defects belongs to the genetically heterogeneous group of classic lissencephalies. It is a diagnosis of exclusion, when neither associated malformations, nor family history is retrieved, in the absence of mutations of genes known to be involved in classic lissencephaly.
