Syndromes with lissencephaly.

paper in 1942 represents a detailed review of early described cases of lis- sencephaly and states that Owen (On the anatomy of vertebrates, vol 3, London: Long- mans, Green & Co, 1868) is said to have introduced the term lissencephaly to describe an agyric brain, from the Greek words "lissos" (smooth) and "encephalus" (brain).' Further reports of lissencephaly followed by Miller,2 Dieker et al,3 Warburg,45 and others and their contributions are recognised in syndromes now known as Miller-Dieker syndrome and Walker-Warburg syndrome.
