Smith-McCort dwarfism (Roy Smith)

Description

Dwarfing skeletal dysplasia with features of the Dyggve-Melchior-Clausen syndrome, however, with normal intelligence. Inheritance is autosomal recessive. The syndrome was first described in 1958 by Smith and McCort, who misinterpreted their findings as Morquio’s disease. The disease picture was delimitated and distinguished form Dyggve-Melchior-Clausen syndrome by the German paediatrician Jürgen Spranger (1931–) et al in 1976.
