Analysis of the human growth hormone receptor and IGF-I coding sequences in children with growth disorders.
Analysis of GHR and IGF-I coding sequences in 47 children with normal serum levels of GH, low IGF-I and growth disorders generally did not show mutation in the genes studied. Only one boy had a mutation located in the fifth exon of the GHR gene (C-->T in codon 88). This suggests that the growth disorders in this group of children might be due to a defect in a DNA region regulating expression of the GHR and IGF1 genes or genes involved in their regulation.
