Mechanisms responsible for dominant expression of human growth hormone gene mutations.

Abstract excerpt

Point mutations of the donor splice site of intron 3 of the human GH-1 gene cause autosomal dominant inherited isolated growth hormone deficiency (IGHD II). The mechanism by which a defect in one GH-1 allele results in GH deficiency is obscure. Previously reported reverse transcription-nested PCR data suggested an overexpression of the mutant GH-1 allele. We employed alternative methods to determine the relative...
