Total Deficiency of Growth Hormone and Prolactin, and Partial Deficiency of Thyroid Stimulating Hormone in Two Dutch Families: a New Variant of Hereditary Pituitary Deficiency (original) (raw)

Hormone Research, 1989

Abstract

Four out of 10 children in two unrelated families presented with a total pituitary growth hormone (GH) and prolactin deficiency and a partial thyrotropin (TSH) deficiency. The GH gene was intact in family I. The pituitaries, visualized by magnetic resonance imaging, were normal. All children responded well to GH and L-thyroxine therapy. Baseline plasma somatostatin and its peak response to arginine infusion were elevated in family I and they had a milder TSH deficiency than family II. Plasma insulin showed a poor response to arginine infusion. This hereditary combination of pituitary deficiencies suggests a deficiency of a common positive transcription factor.
