Background: Zinc transporter 8 autoantibodies (ZnT8Abs) together with glutamic acid decarboxylase autoantibodies (GADAbs), insulinoma antigen 2 autoantibodies (IA-2Abs) and insulin autoantibodies (IAbs) are markers of type 1 diabetes mellitus (T1DM). We studied the prevalence of ZnT8Ab in children with autoimmune thyroid diseases (AITDs) to assess the association of AITDs and T1DM at the serological level.Methods: The st...

Introduction: Salivary androgens represent a non-invasive marker of puberty that may have utility in population studies as well as in the clinical arena.Objectives: To establish normal reference values of salivary androgens using LC-MS/MS and demonstrate the correlations between salivary androgens and pubertal development in boys.Methods: School-based adolescent cohort study with t...

Down syndrome (DS) is characterized by a higher incidence of congenital hypothyroidism (CH) and a high prevalence of subclinical hypothyroidism (SH) early in life. Children and adults with DS have an increased risk of developing autoimmune thyroid disease, however CH and early SH cannot be explained by thyroid autoimmunity. The etiology of CH and early SH in DS remains to be elucidated. Considering the recently discovered genome-wide transcriptional and epigenetic alterations ...

Background: Congenital hypogonadotropic hypogonadism (CHH) is caused by impaired function of GnRH neurons, which clinically manifests by incomplete or absent puberty and infertility. The phenotype may be broader with other developmental anomalies such as anosmia, which is known as Kallmann syndrome. To date, there are more than 40 genes in which mutations underlie CHH. Cornelia de Lange Syndrome (CdLS) is characterized by facial dysmorphia, psychomotor delay, ...

Aim: There is a current lack of international guidelines for managing the endocrine aspects of Noonan syndrome (NS). A clinical practice survey was developed to identify knowledge gaps and differences in the management of patients with NS across Europe.Materials and Methods: A 60-question clinical practice survey was developed for clinical geneticists, paediatric endocrinologists and paediatric cardiologists directly involved in treating...

Background: Long-term glucocorticoid therapy with Prednisolone or Deflazacort has improved outcomes in patients with Duchenne Muscular Dystrophy (DMD), however recommended dosages suppress the hypothalamic-pituitary-adrenal axis, leading to adrenal insufficiency. All boys prescribed glucocorticoid therapy should be assumed to have adrenal suppression, and therefore at risk of adrenal crisis during illness or stress (eg. surgery, bisphosphonate infusions). The ...

Background: We report clinical and molecular cytogenetic characterization of a 13-year-7-month-old boy with a Sotos-like phenotype and de novo NFIX deletions and review the literature.Result: A whole exome sequencing revealed in the present patient with unique clinical phenotypes a de novo frameshift mutation c.570-573delATCA (p.S191Ifs*19) in NFIX gene in 19p13.2.Discussion: The p...

Background: Primary adrenal insufficiency (PAI) in children is an uncommon condition. Diagnosis is usually challenging especially in resource limited settings where facilities for antibodies and genetic testing are constrained. Many genetic etiologies have been reported in children with PAI due to congenital adrenal hyperplasia (CAH) and Allgrove syndrome are the commonest identified genetic causes to date in Sudan. Studies from Africa are rare and here we des...

Introduction: Sulfation is required for the metabolism of numerous compounds, including proteoglycans, steroid hormones, neurotransmitters, toxic chemicals, and drugs like acetaminophen. The sulfate transporter SLC13A1 is responsible for the intestinal absorption and the renal reabsorption of inorganic sulfate, but loss-of-function mutations in this gene have never been described in man. Here, we describe a male with a biallelic loss-of-function variant, i.e.,...

Introduction: Parathyroid Hormone (PTH) is one of the principal regulatory hormones for calcium and phosphate homeostasis. Reduced PTH concentration in hypoparathyroidism is characterised by hypocalcaemia and hyperphosphataemia.Case Presentation: We report a ten-year-old girl who was admitted to the Department of Paediatrics, Endocrinology, Diabetology with Cardiology due to repeated seizures, hypoalcaemia with suspected...
