Background and Objective: Homozygous mutations in the “Centrosomal Protein-19 (CEP19)” gene are extremely rare causes of early-onset severe monogenic obesity. We, herein, report three siblings with CEP19 mutation.Case Presentation and Method: The index case was a 12-years-old female who presented with severe obesity (BMI:62.7kg/m2), metabolic syndrome and diabetic ketoacidosis. Her non-identical twin female s...

Introduction: Pseudohypoaldosteronism type II (PHA II) is an extremely rare disorder characterized by low plasma renin and aldosterone when a normal renal function with hypertension, hyperkalemia, and hyperchloremic metabolic acidosis. PHA II is also known as familial hyperkalemic hypertension or Gordon’s syndrome and is an inherited autosomal dominant. PHA II could be caused by pathogenic variants of WNK1, WNK4, KLHL3, and <em...

Background: Irisin is an adipomyokine secreted by many tissues. Because it has known relationships with the energy metabolism and exercise, its relationships with obesity and type 2 diabetes (T2D) are being focused on. Its relationship with type 1 diabetes (T1D) is unknown.Objective and hypotheses: In this study, the relationships between the serum irisin level and the metabolic control were investigated in adolescents with T1D.Met...

Background: The familial type of isolated GH deficiency (IGHD) is characterized by a variable degree of growth restriction, low but detectable GH serum concentrations. The recessive type 1A and 1B, the autosomal-dominant type 2, and X-linked recessive type 3. Phenotype-genotype correlations are notoriously difficult to be established.Objective and hypotheses: Herein, we described the variable clinical status of a family with a novel GH1 mutation which is...

Objective: This study aims to reveal clinical, hormonal and ultrasound imaging features of patients treated with leuprolide acetate for diagnosis of precoccious puberty.Design: Retrospective analysis of patients with a diagnosis of central precoccious puberty and treated with leuprolide acetate between January 2008 and January 2013.Patients: 81 girls and two boys with early signs of puberty.Results: There was...

Background: Idiopathic hypogonadotropic hypogonadism may be normosmic (nIHH) or it may be associated with anosmia, which is known as Kallmann syndrome (KS). First mutation GNRH1 was described in 2009 in patients with nIHH. Mutations of the human GNRH1 gene are a very rare cause of nIHH, with only six mutations so far described.Case: The proband is a 11.3-year-old boy who first presented at age 1 with micropenis and cryptorchidism. His p...

Background: A 5 years and 10 months boy presented with pubic hair, recent penile growth, aggressive behaviour and rapid growth of height. Antenatal, perinatal, and developmental history was unremarkable. There was no family history of precocious puberty. His height and weight were 128 cm (2.24 S.D.) and 25 kg (1.55 S.D.) respectively. Vital signs were normal. He was Tanner 2 for pubic hair and his stretched penis length was 11 cm, right testis vol...

Background: 5α-Reductase is an enzyme that converts testosterone to dihydrotestosterone (DHT) in peripheral tissues. DHT is responsible for the differentiation of male external genitalia. Mutations in the 5α-steroid reductase type 2 gene (SRD5A2) result in incomplete masculinisation of the external genitalia in subjects with a 46,XY karyotype. The clinical spectrum of a 46,XY individual with 5α-reductase deficiency at birth can range from complete femal...

Background: The steroidogenic acute regulatory protein (StAR) has been shown to be essential for steroidogenesis by mediating cholesterol transfer into mitochondria. Inactivating StAR mutations cause the typical clinical picture of congenital lipoid adrenal hyperplasia.Objective and hypotheses: We aimed to identify causative mutations in cases presenting with adrenal failure during early infancy.Method: Consecutive cases with adren...

Introduction: X-linked adrenal hypoplasia congenita (AHC) is caused by mutations of the NR0B1 gene encoding DAX1 on chromosome Xp21. AHC also occurs as part of a contiguous gene deletion syndrome together with Duchenne muscular dystrophy, glycerol kinase deficiency (GKD), mental retardation, or a combination of these conditions. Here, we report a male 5 years old with AHC who presented with adrenal insufficiency, GKD, and duchenne muscular dystrophy due to a mutation in the DA...
