[Dyggve-Melchior-Clausen syndrome].

The Dyggve-Melchior-Clausen syndrome is a probably autosomal recessively inherited disorder characterized by mental retardation, dwarfism, and skeletal abnormalities especially of the spine, pelvis and hands. It is possibly caused by a disturbance in the protoglycan metabolism. Two Moroccan sibs with this syndrome are described, the first in Dutch literature.
