Improved Genetic Testing for Monogenic Diabetes in the Swiss Population by Targeted Next Generation Sequencing

Dirlewanger Mirjam , Blouin Jean-Louis , Klee Philippe , Castellsague-Perolini Montserrat , Girardin Celine , Santoni Federico , Schwitzgebel Valerie

Background: Monogenic diabetes is a heterogeneous group of diabetes due to a single gene mutation and includes neonatal diabetes (NDM), MODY and rare forms of syndromic diabetes. These forms of diabetes remain undiagnosed in probably more than 90% of patients. The aim of the study was to identify mutations causing monogenic diabetes using a single test.Method: Swiss endocrinologists were proposed to participate in the study and to send blood samples of t...

Ligase IV Deficiency Syndrome as a Cause of Microcephalic Primordial Dwarfism in Dizygotic Twins

Girardin Celine , Ranza Emmanuelle , Klee Philippe , Dirlewanger Mirjam , Caflisch Marianne , Bottani Armand , Schwitzgebel Valerie

Background: Microcephalic primordial dwarfism (MPD) is a group of rare genetic disorders defined by severe growth restriction of both prenatal and postnatal weight (W), height (H), and particularly head circumference (HC).Objective and hypotheses: To elucidate the genetic origin of the MPD in dizygotic twins.Method: Exome sequencing of 19 genes known to be implicated in microcephaly was performed.Results: Diz...

Moya Moya Syndrome in a Patient with Growth Hormone Deficiency and Hypergonadotropic Hypogonadism: to Treat or not to Treat with Growth Hormone Therapy?

Briceno Laura Gabriela Gonzalez , Stoupa Athanasia , Pinto Graziella , Touraine Philippe , Polak Michel

Background: Moya Moya disease is a chronic cerebrovascular angiopathy characterized by progressive stenosis of terminal part of internal carotid vessels and the compensatory development of collateral vessels. We present here the case of a young boy with growth hormone deficiency (GHD) and testicular insufficiency that was diagnosed with Moya Moya syndrome.Case presentation: A 12.9 year-old boy of Serbian origin was referred to the Endocrinology Departmen...

Cushing Disease in a Patient with Beckwith–Wiedemann: an Unusual Association

Brioude Frederic , Nicolas Carole , Netchine Irene , Marey Isabelle , Le Bouc Yves , Touraine Philippe

Background: Beckwith–Wiedemann syndrome (BWS) is an overgrowth syndrome with an increased risk of embryonic tumors during early childhood. About 80% of patients with BWS show a molecular defect in the 11p15 imprinted region. Loss of methylation at the imprinting control region 2 (ICR2) is the most frequent defect which leads to a loss of expression of the CDKN1C gene, increasing cell proliferation. These epigenetic defects occur mostly as a mosaic event.<p cl...

Pegvisomant in Child Acromegaly

Anna Vaczlavik , Cecile Teinturier , Stephan Gaillard , Pierre-Francois Bougneres , Philippe Chanson

Background: Acromegaly is a rare childhood disorder. The use of a growth hormone (GH) receptor antagonist, pegvisomant, has shown great results in adults with acromegaly. We describe results of pegvisomant therapy in two girls with invasive GH pituitary macroadenomas.Case presentation: Case 1: A somatotroph pituitary macroadenoma was diagnosed in a 8-year-old girl with progressive tall stature (height: 148 cm, >+3 S.D.; growth velocity...

Welsch Sophie , Gallo Paola , Beckers Dominique , Lebrethon Marie-Christine , Mouraux Thierry , Seret Nicole , Lysy Philippe

Objective: To provide etiology-based diagnostics to pediatric patients with diabetes in Belgium using routine clinical phenotyping and thorough genotyping.Methods: A Belgian GENEPEDIAB study consortium was created to screen, using routine diagnostic tools, for monogenic forms of diabetes in pediatric patients followed in convention centers for type 1 or type 2 diabetes, while presenting atypical biological and clinical f...

Background: Mutations in the gene encoding LHX4, a homeodomain-containing factor with two LIM domains, are responsible for dominant hypopituitarisms with incomplete penetrance and variable expressivity. To date, only 14 unambiguous LHX4 mutations have been reported. Among those cases, 12 had an absent or ectopic posterior pituitary (EPP) and/or an abnormal sella turcica.Objective and hypotheses: To i) assess the contribution of LHX4 in combined pituitary...
