Background: Wolfram syndrome type 2 (WFS2) characterized by childhood GI ulcers/ bleeding, diabetes, and neurodegeneration with optic atrophy and hearing loss was recently elucidated as caused by CISD2/NAF-1 gene mutation. NAF-1 suppression in cells results in intra-mitochondrial accumulation of iron, increased ROS generation and consequently increased cellular apoptosis. So far only two mutations in four families were reported.Objective: Elucidate the c...

Background: Generalized lymphatic anomaly (GLA) is a rare congenital disorder characterized by aggressive proliferation of dilated lymphatic vessels. The etiology of GLA is poorly understood.Objective and hypotheses: To identify the underlying genetic basis for GLA.Method: Exome sequencing (ES) was performed in two families, including a multigenerational family (family-1) with six affected members. RNA-seq was performed on skin bio...

Background: Hypothalamic-Pituitary–Adrenal (HPA) axis suppression is common during inhaled corticosteroid (ICS) treatment of asthma, and deaths due to adrenal crisis are described. Little is known about the optimal treatment or recovery of ICS induced HPA axis suppression.Aims: To describe the treatment and outcomes of children with ICS induced HPA suppression diagnosed on the low dose short Synacthen test (LDSST).Method: The ...

Background, Objective and hypotheses: GX-H9 is a hybrid Fc-based long-acting recombinant human growth hormone (hGH). The safety, tolerability, and PK/PD of single ascending dose in healthy volunteers were assessed to determine GX-H9 doses capable of normalizing IGF-1 level. The PK/PD, safety, efficacy and tolerability of multiple sequential doses of GX-H9 in adult growth hormone deficiency (AGHD) were compared to that of a daily recombinant hGH in AGHD. A Phase 2 study in pedi...

Background: Mutations in the gene encoding the Chromodomain Helicase DNA-binding protein 7 (CHD7) are found in 60% of patients with CHARGE Syndrome (Coloboma, Heart Defects, Choanal Atresia, Retarded growth and development, Genital hypoplasia, Ear abnormalities and/or hearing problems) and in 6% of patients with Kallmann syndrome.Objectives and hypotheses: To describe a novel CHD7 mutation and its clinical presentation.<p class="abs...

Background: Recombinant human GH (rhGH) is normally administered as a daily s.c. injection. NNC0195-0092 is a reversible albumin-binding GH derivative developed with the aim of reducing clearance and thereby extending the exposure. It has previously been demonstrated that NNC0195-0092 is well tolerated in healthy subjects with the potential for once weekly administration.Objective and hypotheses: In this trial NNC0195-0092 was administrated subcutaneousl...

Background: Early-onset severe obesity due to leptin deficiency typically results from a defect of leptin production or secretion due to mutations in the leptin gene. Recently we described a new form of leptin deficiency caused by bioinactivity of the hormone and associated with high circulating leptin levels (New England Journal of Medicine 2015 372 48–54).Method: Serum leptin was measured by ELISA. The leptin gene was seq...

Background: Insulin-like factor 5 (INSL5), a member of the insulin superfamily, is expressed in the colorectum and hypothalamus. INSL5 levels are elevated by prolonged calorie restriction and declined with feeding, suggesting that it might be an orexigenic hormone.Objectives and hypotheses: Our aim was to explore the relationship between INSL5 and different metabolic parameters in lean and obese subjects and to identify possible links between INSL5 and t...

Background: Maternal obesity can have long-term consequences for the offspring’s health, including increased risk of type-2 diabetes and cardiovascular disease. The C19MC imprinted locus on chromosome 19q13.4 comprises a cluster of 46 microRNAs, which are usually expressed only in the placenta and from the paternal allele exclusively. Besides its role favouring trophoblast migration, the C19MC locus is deregulated in several human cancers. It is unknown ...

Background: Screening for glucose intolerance (GI) or type 2 diabetes (T2D) is recommended for obese children over 10 years of age (or onset of puberty) in the presence of ≧2 of the following risk factors: family history of T2D in a first- or second-degree relative, high risk ethnicity, signs of insulin resistance (IR) or associated conditions, or maternal gestational diabetes. The diagnostic importance of HbA1C levels is still controversial in children and adolescents....
