Novel Growth Hormone-Releasing Hormone Receptor Gene Mutations in Turkish Children with Isolated Growth Hormone Deficiency
OBJECTIVE Isolated growth hormone deficiency (IGHD) is defined as a medical condition associated with growth failure due to insufficient production of GH or lack of GH action. Mutations in the gene encoding for GH-releasing hormone receptor (GHRHR) have been detected in patients with IGHD type IB. However, genetic defects on GHRHR causing IGHD in the Turkish population have not yet been reporte...
متن کاملAnalysis of human growth hormone gene 5' sequences in isolated growth hormone deficiency patients.
Human growth hormone (hGH) gene deletion (6.7 to 7.6 kb) is one of the causes of isolated growth hormone deficiency (IGHD), named IGHD IA. IGHD IA, however, only accounts for about 10% of the total IGHD patients. Most IGHD is caused by unknown mechanisms. Here, hGH gene 5' sequences in three IGHD patients without hGH gene deletion were analysed to see if there was any mutation hindering the exp...
متن کاملGenetic analysis of familial isolated growth hormone deficiency type I.
Nuclear DNA from individuals belonging to nine different families in which two sibs were affected with isolated growth hormone deficiency type I were studied by restriction endonuclease analysis. By using 32P-labeled human growth hormone or the homologous human chorionic somatomammotropin complementary DNA (cDNA) sequences as a probe, the growth hormone genes of affected individuals from all fa...
متن کاملGenetics of Isolated Growth Hormone Deficiency
When a child is not following the normal, predicted growth curve, an evaluation for underlying illnesses and central nervous system abnormalities is required, and appropriate consideration should be given to genetic defects causing growth hormone (GH) deficiency (GHD). Because Insulin-like Growth Factor-I (IGF-I) plays a pivotal role, GHD could also be considered as a form of IGF-I deficiency (...
متن کاملPseudohypoparathyroidism type Ia and growth hormone deficiency. Growth hormone releasing hormone receptor defect?
We report a boy with pseudohypoparathyroidism (PHP), hypothyroidism and low growth hormone (GH) values with no response to growth hormone releasing hormone (GHRH). He presented at age 17 mo because of developmental delay. He had the typical features (short stature, obesity, round face, brachydactyly) of Albright's hereditary osteodystrophy (AHO) and the biochemical profile of PHP; low serum cal...
