Background: 46, XY-disorders of sex development (DSD) are due to different causes like androgen insensitivity, gonadal dysgenesis, defects in testosterone metabolism and others. Exact diagnosis is mandatory prior to medical advice, therapeutic steps, or even surgical procedures. To show the difficulties of gender assignment before and also after a correct diagnosis we describe a patient who waited 35 years for the complete diagnosis, but was advised, treated and operated befor...

Background: Determination of obese children/adolescents at an increased risk of cardio-metabolic complications is of paramount significance for early intervention.Objective and hypotheses: To determine the value of simple anthropometric measures of obesity (BMI-SDS, waist circumference (WC)-SDS, waist-to-height ratio (WHR)) in the determination of individuals at an increased risk for selected cardio-metabolic complications (impaired glucose metabolism, d...

Background: Short stature homeobox-containing gene (SHOX) is located within the pseudoautosomal region 1 (PAR1) of the sex chromosomes. SHOX mutations and PAR1 deletions encompassing SHOX or its upstream/downstream enhancers have been identified in ~60% of Léri-Weill dyschondrosteosis (LWD) and ~5–15% of idiopathic short stature (ISS) patients. Recently SHOX duplications have been described in LWD/ISS individuals.Case presentation: The boy was ...

Background: Recently a heterozygote mutations in the gene ACAN coding the protein aggrecan has been described as a cause of familiar short starture combined with accelerated bone age. The aggrecan is an extracellular proteoglycan in cartilage of growth plates and plays an important role in biological and biomechanical properties of cartilage.Objective and hypotheses: To provide a genetic screening of ACAN within the families with familiar short stature a...

Background: Adrenal insufficiency is a severe condition, which occurs for numerous different reasons. Diseases often require a period or even a lifelong treatment of cortisone and/or mineralocorticoid. Ensuring that families of patients who suffer from adrenal insufficiency have a high level of understanding and knowledge of the disease from the outset is key to them comprehending the severity of the disease, which in turn increases the chances of good complia...

Background: Since the 1980s, growth hormone (GH) treatment has been administered to children as daily subcutaneous (SC) injections. GH-treatment is extremely costly, and requires a high level of training and education, otherwise there is a risk of a poor response to treatment by the patient. This can lead to a waste of time and money for the family. The key to good adherence and successful treatment is patient understanding of the growth/metabolic problem and ...

Background: The SGLT2 (Sodium-Glucose Cotransporter 2) protein is responsible for the majority of glucose reabsorption in the proximal tubule. Mutations in SLC5A2, encoding SGLT2, have been first described in 2002, leading to familial renal glucosuria (FRG). Herein we describe the clinical course of an 11-year-old boy in whom a compound heterozygous SLC5A2-mutation was detected, who presented with glucosuria and vomiting with a suspected diagnosis of diabetes....

Introduction: C-type natriuretic peptide receptor encoded by NPR2 gene stimulates chondrocyte differentiation and hypertrophy and extracellular matrix production within the growth plate. The phenotypical spectrum of NPR2 mutations is broad, from severe autosomal recessive acromesomelic dysplasia to milder autosomal dominant growth disorders. Some children with NPR2 variants are treated with growth hormone (GH), however, with the inco...

Context: Neonatal hypoglycemia due to congenital hyperinsulinism (CHI) is a potentially life-threatening condition. Severe forms of CHI, caused by autosomal recessive variants in KATP channel subunit genes (ABCC8, KCNJ11), are more prevalent in regions with high consanguinity. These regions also have a high neonatal mortality rate with many deaths remaining unexplained.Patients and Methods: We analyze...

Introduction: The main type of diabetes seen in pediatric clinical practice is type 1 diabetes. Monogenic diabetes and syndromic diabetes are rare, but can be more common in areas where consanguinity is high.A 12-year-old girl born to consanguineous parents who are first cousins, was referred after being diagnosed with diabetes and severe diabetic ketoacidosis. In addition, she had hypertrichosis, coarse facial features, acanthosis nigri...
