Introduction: Congenital lipoid adrenal hyperplasia (CLAH) due to mutation in StAR gene, is the most severe form of congenital adrenal hyperplasia (CAH). Affected patient had intracellular cholesterol accumulation in the adrenal glands and tests that manifest clinically in adrenal insufficiency and sex reversal in XY male. Hormonal replacement therapy with physiological doses of glucocorticoids and mineralocorticoids, is the treatment option.<p class="abst...

Background: Primary ovarian insufficiency (POI) manifests with delayed puberty, primary amenorrhea, and elevated levels of gonadotropins (LH, FSH). A variability in genetic factors in the origin of POI has been reported so far. Here we are reporting a case of POI with non-immune diabetes mellitus and mild intellectual disability suspected to have Woodhouse-Sakati Syndrome.Case presentation: A 14 year and 4 months old ado...

Introduction: FOXP3 protein is crucial in enabling T-regulatory cells to maintain tolerance to self-antigens. Mutations in human Foxp3 gene are associated with immune diseases, such as multi-organ autoimmune disorder, immune dysregulation, polyendocrinopathy, enteropathy and X-linked syndrome (IPEX).Case Presentation: A 15 months old male, presented initially at 2 weeks of age with failure to thrive hyperglycemia and sev...

Background: Central diabetes insipidus (CDI) in the neonatal age is usually a result of intracranial insult, either congenital or acquired. Familial CDI is usually an autosomal dominant disorder, presenting later in childhood (1-6 y) with polyuria and mostly caused by mutations in the Neurophysin II moiety of the AVP-NPII prohormone gene; these interfere with prohormone processing leading to gradual destruction of AVP secreting cells and result in arginine vas...

Background: Processing of Precursor 1 (POP1) is a core protein component of the Ribonuclease-Mitochondrial RNA Processing (RNase-MRP) enzymatic complex, an essential complex in all eukaryotes. Mutations in RMRP, encoding the RNA moiety of the complex cause cartilage-hair hypoplasia – anauxetic dysplasia (CHH-AD) spectrum disorders, characterized by severe disproportionate short stature. Recently, five patients harboring mutations in POP1 have been report...

Introduction: Patients homozygous for mutation in the PCSK-1 gene present clinically with severe congenital diarrhea and variable hormonal defects due to lack of enzyme/prohormone processing by Prohormone Convertase 1/3 (PC1/3). Although absence of spontaneous puberty has been reported in patients with PCSK-1 mutations, no peptide hormone(s) in the hypothalamus-pituitary-gonadal axis (HPG) have been reported to be dependent on PC1/3 cleavage. Here we studied t...

Background: Mutations in the gene HSD17B3 encoding the 17-beta hydroxysteroid dehydrogenase 3 enzyme cause testosterone insufficiency leading to XY DSD. In this study the clinical characteristics and molecular etiology of 3 new severe XY DSD cases from consanguineous families are elucidated.Clinical report: Three female patients (2 sisters and a single unrelated female) presented at ages 0.1, 8 and 0.7 years with ambiguo...
