Background: We already described a partial IGF1 primary deficiency due to an exon 4 homozygous missense mutation (g.65941 G>A). A few patients are now described with a heterozygous IGF1 deletion or mutation, questioning about IGF1 haplo insufficiency role in short stature.Results: We describe a boy born from consanguineous parents, with an intra uterine growth restriction (IUGR). Birth weight: 2520 g (−1 SDS) birth length: 46 ...

Of the several genetic defects responsible for thyroid dyshormonogenesis, mutations in TPO gene are the most prevalent causes of inherited defects in CH. Prevalent mutations are in exons 8-11 (catalytic site).Case presentation: Girl, born at 16d after term, before the introduction of the neonatal screening, with asphyxia, BL 55 cm, BW 4 kg. Because of insufficient weight gain, feeding difficulties, prolonged jaundice she was referred to a pediatric endoc...

Background: Congenital sodium diarrhea (CSD) is a monogenic disorder caused by specific genetic defects that increase sodium content in the stool, resulting in intractable diarrhea. There are two categories of CSD depending on whether it involves other congenital malformations: non-syndromic congenital sodium loss diarrhea (non-sCSD) and syndromic congenital sodium loss diarrhea (sCSD). For non- sCSD, the identified causative genes include SLC9A3 and GUCY2C, w...

Introduction: Autoimmune thyroid diseases are multifactorial diseases with a genetic susceptibility and environmental factors. A potential role of the Fas apoptotic inhibitory molecule 2 (FAIM2) gene, the high-affinity alpha subunit (CD25) of the interleukin-2 receptor (IL-2RA) gene, the cytotoxic T cell antigen 4 (CTLA-4) gene polymorphisms on autoimmune thyroid diseases (AITDs) in children has not been established equivocally yet.Objective: To estimate...

Background: Autoimmune thyroid diseases are multifactorial diseases with a genetic susceptibility and environmental factors. A potential role of cytotoxic T-lymphocyte-associated protein 4 (CTLA4) gene, Fc receptor-like 3 (FCRL3) gene, Fas apoptotic inhibitory molecule 2 (FAIM2) gene polymorphisms on autoimmune thyroid diseases (AITDs) in children has not been established equivocally yet.Objective and hypotheses: To estimate the association of polymorphi...

Short-chain L-3-hydroxyacyl-CoA (SCHAD, HADH) deficiency is characterized by diazoxide-responsive hyperinsulinemic hypoglycemia in the neonatal or infancy periods. These patients have severe protein (especially leucine) sensitivity. HADH mutations are recessively inherited with less than 50 patients reported so far. The mechanism behind unregulated insulin secretion in SCHAD deficiency is not understood but may involve changes in protein-protein interactions with glutamate deh...

Introduction: Central Diabetes Insipitus (CDI) results from the inability to secrete ADH secreted by the neurohypophysis system to control water-electrolyte metabolism. In the etiology of CDI many congenital and acquired CNS tumors, infiltrative diseases,infections, autoimmune events, head trauma and idiopathic can be responsible. In this article, a child case with CDI due to intracranial occurence which is very rare in etiology is presented and the approach and follow up are ...

Objective: Hyperthyroidism is rarely seen in the childhood. In this study, we evaluated the reference sign and symptoms and following laboratory and treatment results of the hyperthyroidism cases.Method: Data of the 78 patients were extracted from hospital records retrospectively. Patients’ height, weight, BMI and laboratory results at the time of diagnosis are recorded. Antithyroid drug doses at the 2th, 6th, 12th months after diagnoses are compare...

Background: Mutations in genes encoding type 1 procollagen (T1PC) and proteins responsible for posttranslational modifications of the T1PC heterodimer may result in brittle bone disorder osteogenesis imperfecta (OI). FKBP65 is a known chaperone for type I procollagen and encoded by FKBP10. Autosomal-recessively inherited epidermolysis bullosa simplex and moderately severe OI caused by FKBP10 mutation reported in consanguineous Turkish and Mexican families.</p...

Background: We presented 20-year follow-up of two patients with 11β- hydroxylase deficiency, one of them has novel mutation.Case 1: The male patient was diagnosed at the age of 9-months. He presented with penil growth and pubic hair. At diagnosis blood pressure was normal, his hormonal profile was distinctive of 11β-OHD, with elevated serum levels of 11-deoxycortisol (DOC 134 ng/ml, N: 0–1.18). Hydrocortisone was introduced immediately aft...
