Inhibition of growth hormone (GH) secretion by a mutant GH-I gene product in neuroendocrine cells containing secretory granules: an implication for isolated GH deficiency inherited in an autosomal dominant manner.

Abstract excerpt

Isolated GH deficiency (IGHD) type II is a disease inherited in an autosomal dominant manner. Although point mutations at the donor splice site of intron 3 of the GH-I gene have been identified in patients, the mechanism of how such mutations result in severe GH deficiency is unclear. Recently, we identified two mutations in Japanese patients with IGHD type II, G to A substitutions at the first (mutA) and fifth...
