In Search for New Monogenic Diabetes Genes: PCBD1

Simaite Deimante , Kofent Julia , Gong Maolian , Ruschendorf Franz , Jia Shiqi , Arn Pamela , Bentler Kristi , Ellaway Carolyn , Kuhnen Peter , Hoffmann Georg , Blau Nenad , Spagnoli Francesca , Hubner Norbert , Raile Klemens

Background: Mutations in more than 20 genes are described to cause monogenic diabetes. Nevertheless, numerous families with diabetes of unknown ethology and suspected genetic defect have no molecular diagnosis. This not only impedes our understanding of disease mechanisms but also prevents from predicting the clinical course of the patients and applying the pathogenesis-oriented treatment.Objective: To identify novel gene(s), causing monogenic adolescent...

Identification of Brown Adipocyte Progenitor Marker Genes in Progenitor Cells from Human Deep Neck and Subcutaneous Adipose Tissue by Gene Array Analysis

Tews Daniel , Schwar Verena , Weber Theresia , Scheithauer Marc , Fromme Tobias , Klingenspor Martin , Barth Thomas F , Moller Peter , Fischer-Posovszky Pamela , Wabitsch Martin

Background: Studies in animal models revealed that brown and white adipocytes derive from different progenitor cells. Molecular characteristics of these cells have not been investigated in detail in humans.Objective and hypotheses: To identify novel markers of human brown adipocyte progenitor cells.Method: Progenitor cells from human paired deep neck and subcutaneous adipose tissue samples were obtained from n=12 subjects ...

An Infant with a Novel Kir6.2 Mutation Causing Neonatal Diabetes and Unexplained Lack of Response to Sulphonylurea

O'Connell Susan M , Mc Donald Aoife , O'Toole Norma , Bradfield Anne , Bradley Maura , Hattersley Andrew , Ellard Sian , Proks Peter , Mattis Katia K , Ashcroft Frances , O'Riordan Stephen M P

Background: Neonatal diabetes (NDM) is defined as diabetes developing before 6 months of age, affecting one in 100 000 live births. Permanent NDM is diagnosed in the first 6 months of life with no remission. The majority have a mutation in the ATP-sensitive potassium (KATP) channel (KCNJ11 in 31%, ABCC8 in 13%). Autosomal dominant and recessive forms are described. The majority of patients with NDM caused by KATP mutations respond to sulphonylureas.<p...

Prospective Evaluation of Bone Mineralization, PTH Regulation, and Metabolic Profile in Adult Patients with Hereditary Hypophosphatemic Rickets

Boros Emese , Rothenbuhler Anya , Haidar Hazar , Prie Dominique , Harvengt Pol , Vija Lavinia , Brailly-Tabard Sylvie , Chanson Philippe , Linglart Agnes , Kamenicky Peter

Background: Hereditary hypophosphatemic rickets (HHR) is a rare genetic disease characterized by renal phosphate wasting, caused by elevated circulating FGF23. Despite the current available treatment complications include short stature, hyperparathyroidism, pseudofractures, bone pain, bone demineralization and osteoporosis, nephrocalcinosis and enthesopathies. Elevated circulating FGF23 was recently involved in glucose metabolism and cardiovascular function.<p class="abste...

Background: Pancreas aplasia (PA) and neonatal diabetes mellitus (NDM) syndrome is a rare disease that usually presents in the 1st months of life.Objective and hypotheses: We aimed to characterize molecular genetic defects in a cohort of six NDM/PA patients with up-to-date unknown pathogenesis with optimum genetic testing.Method: As part of our ESPE-RU-project ‘Understanding the molecular basis of diabetes mellitus associated ...

A Recurrent Homozygous NDUFB3 Mutation, p.Trp22Arg Causes a Short Stature Disorder and Mitochondrial Protein Complex I Deficiency with a Variable Metabolic Phenotype

Murray Philip G , Alston Charlottle L , He Langping , McFarland Robert , Shield Julian PH , Morris Andrew A M , Crushell Ellen , Hughes Joanne , Taylor Robert W , Clayton Peter E

Background: Many children with short stature (defined as height SDS <−2S.D.) have no identified cause for their growth impairment and are classified as either small for gestational age or idiopathic short stature depending on birth size. Whole exome sequencing (WES) is a useful tool to identify new genetic diagnoses in this group. Here we describe a recurrent NDUFB3 mutation in children with intra-uterine growth retardation, short stature and ...

Severe Early-Onset Obesity Caused By Bioinactive Leptin due to a N103K Mutation

Wabitsch Martin , Funcke Jan-Bernd , von Schnurbein Julia , Denzer Friederike , Lahr Georgia , Denzer Christian , Moss Anja , Debatin Klaus-Michael , Gierschik Peter , Farooqi Sadaf , Moepps Barbara , Fischer-Posovszky Pamela

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...

Investigation of primary adrenal insufficiency (PAI) in children with 46,XY differences in sex development (DSD)

Man Elim , Peters Catherine , Brain Caroline , Lichtarowicz-Krynska Ewa , Bahl Shailini , Buchanan Charles , Spoudeas Helen , Aitkenhead Helen , Hindmarsh Peter , Dattani Mehul , Achermann John ,

Background: When a baby presents with atypical genitalia, the most important diagnosis to consider is 21-hydroxylase deficiency (21OHD, CAH, 46,XX). However, primary adrenal insufficiency (PAI) can also occur in 46,XY children with differences in sex development (DSD), although this is less common. Known causes of 46,XY DSD-PAI include high blocks in steroidogenesis (STAR, CYP11A1); steroidogenic enzyme defects (HSD3B2, CYP17A1</...
