Background: Congenital generalized lipodystrophy (CGL) is characterized by the absence of most adipose tissue at birth due to an adipocyte differentiation block. For several forms of CGL, the underlying mutation and pathophysiological pathway has been identified. However, for many cases the genetic cause is still unknown.Objective and hypotheses: We report a patient with CGL who showed a complete absence of fat apart from protective fat pads in a postnat...

Background: Published case reports and anecdotal experience suggest a positive effect of dexamphetamine, a CNS stimulant on impetus and weight in patients with hypothalamic obesity. Based on these observations, patients presenting to our obesity clinic with hypothalamic obesity are offered off-label treatment with dexamphetamine.Method: Between 2010 and 2015, patients starting dexamphetamine treatment were enrolled in a prospective observation study. A r...

Background: The melanocortin-4-receptor (MC4R) plays a key role in body weight regulation. Hypothalamic activation of MC4R reduces food intake and increases energy expenditure. Mutations in the MC4R gene lead to the most common cause of monogenetic obesity. More than 150 different mutations are currently known. Their prevalence in obese subjects differs between 0.2 and 5.8%, depending on ethnicity, age and grade of obesity of the analysed cohort. Impact on phenotype a...

Background: It has been suggested that maternal prepregnancy overweight has an effect on childhood overweight.Objective: We aimed to use a survival analysis approach to investigate the association between maternal prepregnancy overweight and childhood overweight in the prospective Ulm Birth Cohort Study (UBCS).Design: At baseline n=1086 mothers and their newborns agreed to participate in the UBCS. Weight and height values ...

Introduction: Disorders of sex development (DSD) refer to a group of conditions, including Turner syndrome in which an individual's physical sex characteristics do not conform to typical male or female patterns, including a range of differences in chromosomes, hormones and anatomy. Gender-specific problems are usually not prominent, compared to other forms of DSD. Gender dysphoria (GD) is a discomfort between a person’s assigned sex based on physica...

Background: Steroidogenic factor (SF1, NR5A2) regulates multiple genes known to be involved in gonadal development, adrenal development, steroidogenesis, and gonadotroph development. Heterozygous mutations in the NR5A1 gene have been described in association with mild to severe gonadal dysgenesis with or without adrenal failure. Homozygous mutations are rare and have also been described in association with gonadal dysgenesis with or without adrenal failure.<p class="abstex...

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...

Shwachman-Diamond syndrome (SDS) is a rare congenital disease, which is caused by SBDS gene mutations. The main characteristics of SDS are pancreatic exocrine deficiency, hematological dysfunction, and skeletal growth failure. Emerging data from case reports and patient registries suggest, that SDS could also be associated with an increased risk for diabetes mellitus. Additionally, a small number of case reports in the literature describe a susceptibility to hypoglycaemia as a...

MicroRNAs (miRNAs) are small non-coding RNA molecules and play an important role in the post-transcriptional regulation of gene expression and thereby influence important cellular functions. In adipocytes, miRNAs regulate key processes such as differentiation, inflammation, metabolism, and adipokine secretion. Recently, we found that miR-27a is upregulated under proinflammatory conditions in human adipocytes. Thus, our goal was to better understand the function of miR-27a in a...

Background and Objective: Homozygous mutations in the “Centrosomal Protein-19 (CEP19)” gene are extremely rare causes of early-onset severe monogenic obesity. We, herein, report three siblings with CEP19 mutation.Case Presentation and Method: The index case was a 12-years-old female who presented with severe obesity (BMI:62.7kg/m2), metabolic syndrome and diabetic ketoacidosis. Her non-identical twin female s...
