Neonatal Diabetes due to NKX2.2 Mutation – Genotype, Clinical Phenotype and Therapeutic Challenges in a Very Low Birth Weight Diabetic Neonate

Auerbach Adi , Shlomai Noa Ofek , Shokrun Ariella Weinberg , Levy-Lahad Ephrat , Zangen David

Background: Insulin treatment in a very low birth weight neonate having persistent hyperglycemia is challenging. The very recently reported novel human genetic cause of neonatal diabetes due to NKX2.2 pancreatic transcription factor mutations is associated with very low birth weight deliveries.Objective and hypotheses: To study the diagnostic process, the molecular genetics, the clinical phenotype, and the significant therapeutic challenges in the manage...

Background: Classical and non-classical congenital lipoid adrenal hyperplasia (CLAH) are extremely rare condition caused by mutations in StAR. The degree of enzyme activity impairment determines the clinical phenotypes.Objective and hypotheses: To identify the genetic cause of primary adrenal insufficiency in a cohort of patients from 13 unrelated families with classical and non-classical CLAH, to correlate genotype to phenotype and to identify ...

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...
