Background: NKX2-2 gene mutation (reported in 3 cases worldwide) cause severe IUGR and neonatal diabetes. Beta-cells of the mice Nkx2-2 (−/−) model were recently shown to convert into cells producing the appetite-promoting peptide ghrelin. Classically, ghrelin secretion is stimulated during fast and suppressed by nutrients or glucose ingestion in all age groups. In obese children this ghrelin suppression reaches a minimum of 60% of base...
