Abstract

Two male patients with congenital cleft lip and palate first seen at ages 10.2 and 21.5 years presented with typical signs of hypothalamic-interior pituitary hormone deficiencies. They were found to lack GH, LH, and FSH and to be partially deficient in TSH and ACTH. Several congenital defects may explain this rare syndrome affecting midline structures in the proximity of the maldeveloped palate, including Rathke's pouch, which migrates distally to develop into the anterior pituitary.
