Abstract excerpt
Growth failure in children with high growth hormone (GH) levels, low insulin-like growth factor 1 (IGF-1) levels, and accelerated linear growth in response to exogenous GH is presumed to result from biologically inactive GH. A molecular diagnosis has only been made in two such patients. We analyzed the presentations and the GH-1 genes of twin Egyptian brothers with this phenotype. At 8 yr of age, the boys'...
