Kahveci Ahmet , Kaplan Gunay , Arslan Ateş Esra , Bilge Geckinli Bilgen , Guran Tulay , Turan Serap , Bereket Abdullah , Haliloglu Belma

Background: Hepatocyte nuclear factor 1β (HNF1β) is a critical transcription factor that regulates the development of the kidneys, pancreas, liver and genital tract. Patients with deletions and mutations in the HNF1 β gene present with renal and extrarenal manifestations. The most important extrarenal finding is diabetes, also known as MODY5. Although it is generally diagnosed with hyperglycemia, diabetic ketoacidosis is rarely seen.<p class...

Background: Hereditary hypophosphatemia (HH), is a rare condition related to decreased renal tubular phosphate reabsorption. Although X-linked hypophosphatemia (PHEX mutation) is the most frequent cause of HH, recent advances in the next-generation sequencing (NGS) techniques enable the identification of various genetic etiologies. Our study aims to determine the molecular etiology of patients with hypophosphatemia and to identify new candidate genes....

Post-OGTT hypoglycemia is common in Cystic Fibrosis(CF). The aim of the study is to determine of the role of glucagon in the pathogenesis of hypoglycemia in CF patients. A 3-hour-OGTT was performed fifty-three subjects (44CF,9 age-matched controls). Sixteen (36.4%) subjects had normal glucose tolerance (NGT), 13 (29.5%) had isolated hypoglycemia (IsoHypo), 8 (18.2%) had hypoglycemia with abnormal glucose intolerance (Hypo+AGT), 5 (11.4%) had AGT and 2 (4.5%) had CFRD. After AG...

Two Cases with Hypergonadotropic Hypogonadism Due to Derivative X Chromosome

Elmaoğulları Selin , Sezer Abdullah , Öztoprak Ülkühan , Berna Çelik Ertaş Nur , Savaş Erdeve Şenay , Çetinkaya Semra

Introduction: A derivative chromosome (der) is a structurally rearranged chromosome generated either by a chromosome rearrangement involving two or more chromosomes or by multiple chromosome aberrations within a single chromosome. Balanced segmental anomalies such as inversion or translocation can lead to derivative chromosomes with partial duplication and deletion during meiosis. Here we present two patients with hypergonadotropic hypogonadism and various acc...

A worldwide increase in pediatric thyroid cancers incidence over the years has been observed. Although pediatric thyroid cancers tend to have a more aggressive course compared to adults, the survival rate is better. In this study, we aimed to examine the demographic, clinical, pathological, and laboratory characteristics, prognostic and risk factors of children with thyroid cancer.Methods: We retrospectively analyzed 39 children with thy...

Context: The 45,X/46,XY mosaicism poses a great clinical challenge influencing gonadal development, histology, hormonal balance, and growth. Patients present a wide spectrum of phenotypes with varying degrees of genital ambiguity from Turner Syndrome to male. Here, we present five children with 45,X/46,XY mosaicism presenting with different clinical phenotypes.Case Descriptions:Case 1:</str...

CHD7 Mutations in Patients with Anosmic or Normosmic Idiopathic Hypogonadotropic Hypogonadism

Damla Kotan Leman , Anik Ahmet , Mengen Eda , Turan Ihsan , Akkus Gamze , Ozsu Elif , Bereket Abdullah , Nuri Ozbek Mehmet , Yuksel Bilgin , Kemal Topaloglu Ali

Background: Mutations in CHD7 cause a rare multi-organ system disorder, CHARGE syndrome (CS). Genital hypoplasia has been described in 60-80% of reported cases because of idiopathic hypogonadotropic hypogonadism (IHH), which is a result of inadequate GnRH secretion in the hypothalamus. Correspondingly, IHH and anosmia are expected in cases with CHD7 mutation. However, due to the phenotypic spectrum of CHD7, mutations have also be...

Background: Liquid chromatography-mass spectrometry (LC-MS) based panels of steroid hormones and their precursors offer a distinct pattern of steroid metabolome for various disorders of adrenal and gonadal steroidogenesis. However, it may not be easy to handle this high throughput data rapidly in clinical setting which requires expert opinion for correct interpretations. Analytical results of steroid panelling can be allied to automated review systems to simpl...
