Short stature, craniofacial dysmorphism and dento-skeletal abnormalities in a large kindred. A variant of K.B.G. syndrome or a new mental retardation syndrome.

A possibly new mental retardation syndrome is described in a large family. The major features of the syndrome are: short statue, craniofacial dysmorphism and dento-skeletal abnormalities. The mode of inheritance of this syndrome appears to be autosomal dominant with a variable degree of expressivity. The possible similarity to another autosomally dominant inherited mental retardation syndrome, "the K.B.G. syndrome" as described by Hermann et al. (1975), is discussed.
