Description : Fryns et al. (1990) described a family in which 4 (3 males and 1 female) of 12 children
from healthy, nonconsanguineous parents had a combination of moderate mental retardation,
peculiar craniofacial dysmorphism, hypergonadotropic hypogonadism, eunuchoid habitus,
diabetes mellitus, and epilepsy. All were investigated as adults. The diabetes was
type I beginning in the teens. The craniofacial features included a narrow-based but
broad nose with coloboma of the alae nasi, deep-set eyes, and a long face with relative
mandibular prognathism. *FIELD* RF 1. Fryns, J. P.; Vogels, A.; van den Berghe, H.:
