Other Reports


Jaatoul et al (1982) described a consanguineous family in which four siblings were suspected to have Marden-Walker Syndrome. The male propositus presented as a 10-month old with failure to thrive, psychomotor retardation and multiple congenital anomalies. He had three older siblings who had all died as neonates and had similar congenital anomalies. The parents were healthy.
