Introduction: The envelope protein of Human Endogenous Retrovirus type W (HERV-W-Env) has been shown to be associated with type 1 diabetes (T1D) pathogenesis in adults patients. This protein is expressed in pancreas of T1D patients and it seems to correlate with macrophage infiltrations. In vitro and in vivo studies have demonstrated that HERV-W-Env inhibits insulin secretion and promotes hyperglycemia. Furthermore, HERV could be implicated in other auto-immune disorders. The ...

Background: Androgen excess in childhood is a common clinical presentation and might signify serious pathology. We have recently explored patterns and severity of androgen excess in a large female adult cohort to differentiate common polycystic ovarian syndrome (PCOS) from non-PCOS pathology, including congenital adrenal hyperplasia (CAH), ovarian hyperthecosis and adrenal and ovarian tumours (Elhassan et al., JCE&M 2018). Herein, we undertake a similar approach f...

Hypospadias in a Male Patient with 21-Hydroxylase Deficiency and Atypical Clinical Course: Presentation of Two Brothers

Guven Ayla , Hancili Suna , Arlt Wiebke

Introduction: 21-Hydroxylase deficiency (21OHD) is the most common form of congenital adrenal hyperplasia (CAH). Clinical and laboratory findings vary depending on the enzyme activity.Case Report 1: A 2-month-old male infant referred as hypospadias. He was born at term from consanguineous parents with intrauterine growth retardation. The mother had no problem during pregnancy. The external genitalia had penoscrotal hypospadias with chordee and both teste...

Thyroid Hormone Transporter Defects

Visser W Edward

Thyroid hormone is crucial for metabolism and development. Cellular thyroid hormone homeostasis requires adequate function of (i) thyroid hormone transporter proteins, (ii) deiodinating enzymes and (iii) nuclear receptors. Thyroid hormone transporters are crucial for cellular uptake of T3 and T4. Over the last years, a number of thyroid hormone transporters have been identified and their physiological relevance has been established. The most well-studied example is MCT8 defici...

RNA Sequencing Reveals the Pathways Perturbed by Redox Imbalance in Nicotinamide Nucleotide Transhydrogenase Null Mice

Meimaridou Eirini , Goldsworthy Michelle , Chortis Vasileios , Foster Paul , Arlt Wiebke , Cox Roger , Metherell Louise

Background: In humans, loss-of-function mutations in Nicotinamide nucleotide transhydrogenase (NNT) cause familial glucocorticoid deficiency, a potentially fatal, adrenal-specific disorder characterized by increased ACTH and reduced cortisol levels. NNT is a highly conserved inner mitochondrial membrane protein, which supplies high concentrations of NADPH for detoxification of reactive oxygen species (ROS) by glutathione and thioredoxin pathways.<p class="abstext"...

Multiple Malformations Extending the Phenotypic Spectrum of Antley–Bixler Syndrome in a Patient with P450 Oxidoreductase Deficiency due to Two Novel Mutations of the POR Gene

Janchevska Aleksandra , Idkowiak Jan , Caredda Elisabeta , Hurst Jane , Dattani Mehul T , Arlt Wiebke , Spoudeas Helen A

Background: P450 oxidoreductase deficiency (PORD) is characterised by glucocorticoid and sex steroid deficiency and skeletal malformations, resembling Antley–Bixler syndrome (ABS, MIM 124015), a skeletal malformaton phenotype also present in patients with fibroblast growth factor receptor 2 mutations (FGFR2, MIM 176943). While genetic testing confirms both conditions, establishing the exact diagnosis on clinical grounds can be challenging.Objective ...

Identification of Syndromal Macrosomia: Macrocephaly, but Neither Height Nor Weight Data are Useful in the Detection of Pediatric PTEN Hamartoma Tumor Syndrome (PHTS)

Plamper Michaela , Gohlke Bettina , Schreiner Felix , Wölfle Joachim

Background: PTEN Hamartoma Tumor Syndrome (PHTS) encompasses different syndromic disorders which are associated with autosomal-dominant mutations of the tumor suppressor gene PTEN. Patients are at high risk to develop benign and malignant tumors. Macrocephaly is a diagnostic feature, but there is a paucity of data on prevalence, degree und development during growth. Charts for length, weight and head circumference for this rare disorder do no...

Clinical and Cost-Effectiveness of GH Treatment for Children in Wales

Pop Raluca-Monica , Warner Justin T. , Gregory John W.

Background: GH treatment has been used for the last 30 years for children with short stature with varying individual responses.Objective: Analysis of final height SDS (standard deviation score) and the factors influencing it in children treated with growth hormone.Material and methods: Subjects across Wales who received GH treatment, part supervised by tertiary center staff and reached final height while on treatment, were identifi...
