We studied 101 growth-retarded children from the population of Ancona (Italy). Plasma growth hormone (GH) levels at the end of insulin and clonidine tests were considered for classification of children into 3 categories according to severity of GH deficit: total deficit of GH (TD), partial deficit (PD, and familiar short stature (FSS; no deficit of GH). The BGLIIA*2/BGLIIB*1 haplotype of GH cluster that was previously found to be negatively associated with severe glucose intolerance in non-insulin- dependent diabetes mellitus (NIDDM) is negatively associated with GH deficit in growth-retarded children. The hypothesis that intrauterine growth retardation and glucose intolerance in adult life could be phenotypes of the same underlying genotype has been recently put forward. The present observation suggests that genes influencing both growth and glucose tolerance are encoded in the GH cluster. Copyright 2002 by W.B. Saunders Company

Abstract
We studied 101 growth-retarded children from the population of Ancona (Italy). Plasma growth hormone (GH) levels at the end of insulin and clonidine tests were considered for classification of children into 3 categories according to severity of GH deficit: total deficit of GH (TD), partial deficit (PD, and familiar short stature (FSS; no deficit of GH). The BGLIIA*2/BGLIIB*1 haplotype of GH cluster that was previously found to be negatively associated with severe glucose intolerance in non-insulin- dependent diabetes mellitus (NIDDM) is negatively associated with GH deficit in growth-retarded children. The hypothesis that intrauterine growth retardation and glucose intolerance in adult life could be phenotypes of the same underlying genotype has been recently put forward. The present observation suggests that genes influencing both growth and glucose tolerance are encoded in the GH cluster. Copyright 2002 by W.B.
