Background: X-linked AHC is a rare disorder of the adrenal cortex caused by mutations in the NR0B1 (DAX1) gene. NR0B1 (DAX1) encodes for an orphan nuclear hormone receptor which is expressed in the adrenal, gonad, hypothalamus, and pituitary glands. Hypogonadotropic hypogonadism (HH) is the most frequently observed puberty disorder (absent or delayed puberty) caused by mutations in the NR0B1 (DAX1) gene and is due to impaired gonadotropin synthesis a...

Background: Hypophosphatemic rickets (HR) is a group of rare disorders caused by excessive renal phosphate wasting. The dominant form of HR is X-linked HR (XLHR) caused by mutation in the phosphate-regulating endopeptidase gene PHEX. There is also autosomal dominant form of HR caused by mutation in FGF23 gene or rare autosomal recessive form caused by DMP1 mutation. The phenotype can vary from very delicate to severe bone disease.<p class="abstex...

Background: Dysregulation of phosphate homeostasis in diseases such as tumor-induced osteomalacia and chronic kidney disease are often associated with impairment of musculoskeletal tissue function. While various factors such as intracellular calcium levels and dysegulated endocrine mechanisms are thought to contribute, the role of single factors such as phosphate and its main regulating hormone FGF23 are only partly revealed.Objective and hypotheses: Ino...

Background: It has been discussed in literature, that being severely obese and adolescent are predictive for failure in a behavior based weight-loss program.Objective: To investigate the association between age and initial BMI-SDS with BMI-SDS courses during and after the attendance of an inpatient weight-loss program.Design: The LOGIC-trial involves overweight and obese children and adolescents (6–19 years), who participate i...

Background: Congenital hyperinsulinism (CHI) is the most common cause of the persistent hypoglycemia in children. Mutations in KCNJ11 and ABCC8 genes coding potassium channel subunits are responsible for a significant proportion of CHI patients. The type of mutation correlates with the type of B-cell hyperplasia (focal or diffuse), and determinates further diagnostics, treatment and prognosis of disorder.Aims and objectives: The aim of ...

Background: Congenital primary hypothyreoidism occurs in about 1 of 3 600 life births and is usually detected with newborn screening. Early levothyroxine treatment is the prerequisite for normal psychomotor development of affected children. However, patients suffering from congenital central hypothyroidism are missed by the screening procedure, which may lead to delayed diagnosis and therapy. In very rare cases central hypothyroidism is caused by isolated TSH deficiency due to...

Background: In the vast majority of cases, achondroplasia and hypochondroplasia are attributable to hotspot missense mutations in the FGFR3 gene. 96% of patients have a G(1138)A and 3% have a G(1138)C point mutation. We report on a family whose members have a deep intronic mutation that leads to a novel cryptic splicing variant of the FGFR3 gene, and via this pathway results in new pathogenicity manifesting as achondroplasia.Case...

We report on a nearly 4-year-old girl who presented to the emergency room of our paediatric clinic with high fever and poor general condition, swelling of the neck and swallowing difficulties. Laboratory chemistry showed a marked hyperthyroid metabolic state, so that initially a thyrotoxic crisis in Graves' disease was considered (TSH 0.03 mU/L (-), fT4 28.10 pmol/l (+)). Therefore, a short-term therapy with thiamazole was given. The thyroid autoantibodies were negative. ...

The Loeys-Dietz syndrome (LDS) is a genetic heterogeneous, autosomal dominant aortic aneurysm syndrome with widespread systemic involvement. As defined by Loeys et al. (2006), the disorder is characterized by the triad of arterial tortuosity and aneurysms, hypertelorism, and bifid uvula or cleft palate. We present a 16.5-year-old girl with LDS2 caused by a mutation c.1582C>T (p.R5228C) in the TGFBR2 gene and treated with recombinant growth hormone (rGH) du...

It has been established that a random growth hormone (rGH) level can be obtained and is useful within the first 28 days of life for establishing a diagnosis of congenital growth hormone deficiency (cGHD). However, it remains unclear if weight-for-length (WfL), a surrogate for adiposity, impacts these levels, similar to how body mass index in older subjects impacts peak growth hormone levels derived from provocation testing. The objective of this study is to determine the impac...
