A Novel Missense Variant in the Insulin Receptor Gene in Three Unrelated Irish Families with Severe Insulin Resistance Syndrome: Evidence for an Irish Founder Effect

Mavinkurve M , O'Connell S , Cody D , Isaac I , Harris J , Semple R K , Mc Donnell C

Background: Genetic defects in the insulin receptor (INSR) are rare. Precise prevalence is unknown and significant clinical heterogeneity exists. Over 120 allelic variants have been described to date, spread throughout the receptor, and few geographical founder effects have been described. In this case series we identify a novel missense mutation in the tyrosine kinase domain of the INSR in three independently ascertained Irish families.Objective and Hyp...

Prenatal Exposure to Phthalates and Phenols in Relation to Anogenital Distance at Birth in Male Infants

Fisher Benjamin G , Thankamony Ajay , Ong Ken K , Dunger David B , Hughes Ieuan A , Acerini Carlo L

Introduction: Increasing incidence of male reproductive disorders may be due to fetal exposure to putative endocrine disruptor chemicals (EDCs), such as phthalates and phenols. Anogenital Distance (AGD) is a biomarker of fetal androgen action in animals, and has recently been linked to testicular dysgenesis syndrome in humans.Objective: To examine the relationship between prenatal phthalate and phenol exposure and birth AGD in male infants.<p class="...

Severe 21-Hydroxylase Deficiency Congenital Adrenal Hyperplasia and Congenital Hypothyroidism Due to Thyroglobulin Mutations in a Single Family: Two Distinct Genetic Disorders with Phenotypic Variability within a Single Family

Ponmani Caroline , Atterbury Abigail , Seniappan Senthil , Schoenmakers Nadia , Nicholas Adeline K , Chatterjee Krishna , Dattani Mehul

Background: 21-Hydroxylase deficiency due to mutations in CYP21A2 represents the commonest form of congenital adrenal hyperplasia (CAH). Dyshormonogenetic congenital hypothyroidism (CH) may be due to TPO, TG, DUOX2, DUOXA2, IYD, SLC5A5 and SLC26A4 mutations.Objective and hypotheses: We report a kindred with three siblings born to unrelated parents manifesting with two different forms...

Effects of Recombinant Human GH on Bone Mass and Body Composition in Paediatric Inflammatory Bowel Disease

Altowati M A , Shepherd S , McGrogan P , Russell R K , Ahmed S F , Wong S C

Background: rhGH therapy may improve linear growth in children with inflammatory bowel disease (IBD). Poor bone health and abnormal body composition are recognised complications in paediatric IBD.Objective and hypotheses: To investigate the effects of rhGH on bone health and body composition.Method: Sub-analysis of 13 children with IBD (12CD; 1UC) in a randomized controlled trial. Either rhGH (0.067 mg/kg per day) as daily s.c. inj...

A Korean Boy with Pseudohypoparathyrodism Type Ia Presenting with Congenital Megacolon and Spinal Stenosis: Identification of a Novel GNAS Gene Mutation

Lee J E , Lee S H , Cho S Y , Ki C S , Jin D K

Pseudohypoparathyroidism (PHP) is a disease of rare frequency. There are five subtypes with each having different phenotypes and blood laboratory test results, which depend on gene mutation and hereditary styles. Among them, the most common type is PHP Ia which inherits maternal gene mutation and expresses Albright’s hereditary osteodystrophy (AHO) appearance, hypocalcemia, hyperphosphatemia and serum parathyroid hormone elevation. Another type, pseudo-pseudohypoparathyro...

Analysis of CD133+CD45+ Hematopoietic Progenitor/Stem Cells and CD133+/CD45- Very Small Embryonic-Like Stem Cells in Children with GH Deficiency Subjected to GH Therapy

Bossowski A , Singh P , Grubczak K , Radzikowska U , Sawicka B , Miklasz P , Dabrowska M , Bossowska A , Moniuszko M

Background: GH deficiency (GHD) is an endocrine condition, caused by problems arising in the pituitary gland that does not produce sufficient quantities of GH. GHD is treated by replacing GH with one daily injections. Recent studies suggested that GH could be involved in regulation of certain stem cell subset potential and function. However, the exact effects of GH therapy on biology of stem cells in paediatric patients were not studied in detail.Methods...

Syndromic Hypoketotic, Hypoinsulinemic Hypoglycaemia due to a Mosaic Activating Phosphatidylinositol 3-Kinase Mutation

Kummer Sebastian , Leiter Sarah M , Welters Alena , Barroso Ines , Meissner Thomas , Semple Robert K

Background: In contrast to hypoglycaemia due to congenital hyperinsulinism, there are patients with a similar metabolic profile of hypoketotic hypoglycaemia, but low insulin levels and relatively low glucose requirements to maintain euglycaemia. So far, four patients with activating mutations in the insulin signal-transducing kinase AKT2 have been described, each also showing a syndromic phenotype including hemihypertrophy.Objective and hypotheses: We pr...

A CYP21A2 Gene Mutation in Patients with Congenital Adrenal Hyperplasia: Molecular Genetics Report from Saudi Arabia

Mohamed Sarar , El-Kholy Suzan , Al-Juryyan Nasir , Al-Nemri Abdulrahman M , Abu-Amero Khaled K

Background: Although the clinical presentations of congenital adrenal hyperplasia (CAH) have been studied in Saudi children, the literature review revealed no molecular report of 21-hydroxylase was published.Objective and hypotheses: The aim of this study was to determine the pattern of CYP21A2 gene-mutations of CAH in Saudi children.Method: Between January 2011 and March 2014 at King Fahad Military Complex, Dhahran, Saudi Arabia, ...

Study of Adiponectin Level in Diabetic Adolescent Girls in Relation to Glycaemic Control and Complication of Diabetes

Dayem Soha Abd El , Nazif Hayam K , Kader Mona Abd El , El-Tawil Maha , Battah Ahmed

Objective: To determine the influence of adolescent girls with type 1 DM on circulating levels of adiponectin and to study the relation between adiponectin level with glycemic control and complication of diabetes.Patients and methods: The study included 40 female adolescent type 1 diabetic patients and 40 healthy volunteer of the same age and sex. Blood sample was taken for assessment of glycosylated haemoglobin, lipid profile and adiponectine. Urine sam...

Thyroid hormone resistance syndrome due to a new mutation in the TRHA gene

Tuhan Hale , Donbaloğlu Zeynep , Kırbıyık Özgür , Parlak Mesut , Demir Korcan

Introduction: Resistance to thyroid hormones is defined as lack of response of peripheral tissues to triiodothyronine (T3) which is the active form of thyroid hormones. In general (85%) a mutation is detected in the thyroid hormone receptor β (THRB) gene and more rarely, the thyroid hormone receptor α (TRHA) gene.Case: A 4.7-year-old boy, was admitted to the pediatric endocrinology outpatient clinic of Akdeniz...
