Elaboration of the phenotypic changes of the upper limbs in the Neu-Laxova syndrome.

We present two new cases and data from a detailed study of the upper limbs (structural changes, the state of peripheral nerves, arteries, muscles and bones) of three stillborn infants with the Neu-Laxova syndrome. The morphogenesis of many of the examined anatomical structures in these fetuses was anomalous. The origin of these anomalies is discussed.
