A Novel Mutation of IGSF1 Gene

Sotiridou Ellada , Schoenmakers Nadia , Datta Vipan

Introduction: Mutations in IGSF1 result in X-linked congenital central hypothyroidism, macroorchidism and a variable spectrum of anterior pituitary dysfunction, most commonly including hypoprolactinaemia. We identified a novel hemizygous IGSF1 mutation (c.3191T>C, p.L1064P) in a 17 year-old adolescent, inherited from his heterozygous mother.Case: A novel hemizygous IGSF1 mutation (c.3191T>C, p.L1064P) was identified by direct se...

A Novel Mutation in the Thyroglobulin Gene Leading to Neonatal Goiter and Congenital Hypothyroidism in an Eritrean Infant

Stern Eve , Kassif Eran , Schoenmakers Nadia , Gruber Noah , Pinhas-Hamiel Orit , Yeshayahu Yonatan

Background: Congenital hypothyroidism is a common condition with reported incidence between 1/2000 – 1/4000 live births. In approximately 85% of cases this is sporadic due to a structural abnormality of the thyroid gland. Approximately 15% of cases are hereditary and secondary to thyroid dyshormonogenesis. Most of these are due to mutations in one of the genes involved in iodine transport or organification, mutations in the thyroglobulin gene or d...

Thyroglobulin deficiency: a rare cause of neonatal stridor

Tseretopoulou Xanthippi , Reddy Nithya , Pinnamaneni RagaMallika , Jonas Nicolaas , Schoenmakers Nadia , Walton-Betancourth Sandra

Background: Nonimmune neonatal goitrous hypothyroidism is a rare cause of neck mass and stridor. Retropharyngeal extension, described in 7% of cases of goitre spreading outside the thyroid bed, represents a diagnostic dilemma that requires a systematic multimodality imaging approach combined with hormonal and genetic analysis. We report the case of a one-week-old baby who presented with stridor and respiratory distress, without palpable neonatal goitre and whose biochemical pr...

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...

Genotype and Phenotype Characterization of a Series of Italian Patients Affected with Idiopatic Central Hypothyroidism

Bonomi Marco , Duminuco Paolo , Salvatoni Alessandro , Maggi Mario , Buzi Fabio , Pilotta Alba , Radetti Giorgio , Beck-Peccoz Paolo , Campi Irene , Schoenmakers Nadia , Joustra Sjoerd , Wit Jan Maarten , Bernard Daniel , Nespoli Luigi , Bozzola Mauro , Persani Luca

Background: Central hypothyroidism (CeH) is a rare thyroid hormone deficiency due to an insufficient stimulation of a normal thyroid gland. Candidate genes for isolated CeH include TSHβ, TRH receptor (TRHR) or IGSF1 genes while the combined pituitary hormone deficits (CPHDs) are the consequence of defects in embryonic pituitary transcription factors or in the prokineticin receptor 2 (PROKR2).Patients series: Here we report nine males (M) and 15 fema...

Missense Mutation of GLIS3 Gene Resulting in Neonatal Diabetes and Congenital Hypothyroidism

Alghazir Nadia

Background: Neonatal diabetes, diabetes diagnosed before 6 months of age, is rare, with incidence of approximately 1:90,000–160,000 live births. In approximately half of cases, neonatal diabetes is transient and usually resolves between 6 and 18 months of life. In the remainder of cases, the diabetes is permanent. Mutations in the GLI-similar 3 (GLIS3) gene encoding the transcription factor GLIS3 are a rare cause of permanent neonatal diabetes and congen...

Aromatase Inhibitor Treatment in Patient with Beta-Human Chorionic Gonadotrophin Secreting Tumor and Gonadotropin-Independent Precocious Puberty

Kiiaev Aleksei , Mazerkina Nadia , Astashova Ekaterina

Introduction: CNS tumors may cause precocious puberty (PP): in most cases gonadotropin-dependent PP, but in boys ß-HCG- secreting tumors may cause gonadotropin-independent (GIPP) with extremely high testosterone secretion due to Leidig cell stimulation by ß-HCG. Rapid bone maturation in such cases can lead to growth plate closure and poor final height prognosis. Aromatase inhibitor (AI) are administered in children with McCune-Olbright disease, famil...

Incidence of Cranial MRI Abnormalities in Patients with Isolated Growth Hormone Deficiency: 20 Years of Results

Amin Nadia , Biliaieva Kateryna , Mushtaq Talat

Background: Patients with isolated growth hormone deficiency (GHD) will routinely have an MRI scan of the pituitary and brain to assess pituitary size and presence of any intracranial lesions. The result may change the threshold for monitoring for further hormone deficiencies. However the test may also detect unexpected or unrelated abnormalitiesAim: To review the incidence of normal and abnormal MRI scans in children with a diagnosis of isolated GHD.</p...

Results of GH Treatment in Childhood Brain Tumours Survivors

Mazerkina Nadia , Gorelyshev Sergey , Geludkova Olga

Background: GH deficiency is the most common endocrine disorder in childhood brain tumours survivors.Objective and hypotheses: To examine results and safety of GH treatment in patients with childhood brain tumours.Method: 118 patients (72 craniopharyngioma, 29 medulloblastoma, 17 germ cell tumours) received hGH in the dose 0.03–0.034 mg/kg per day for 2.3±0.8 years. The mean chronological age at the start of the treatment...
