CG at the Methylation IGF1 Locus is an Epigenetic Predictor of GH Sensitivity

Ouni Myriam , Castell Anne Laure , Bougneres Pierre

Background: The growth and IGF1 responses to GH treatment show a large variation across children with idiopathic short stature (ISS). Compliance and GH regimens are important determinants. The d3 variant of the GH receptor (GHR) is a significant genetic predictor. The role of individual epigenetics had not been studied. The IGF1 locus is an attractive candidate where CG methylation could influence GH action.Objectives: To study GH effects on a) IGF1 gene...

CG Methylation at the IGF1 P2 Promoter is a Major Epigenetic Determinant of Postnatal, Not Foetal Growth

Ouni Myriam , Le Stunff Catherine , Castell Anne Laure , Bougneres Pierre

Background: The height of children has a Gaussian distribution. Genetics explain an important part of individual variability, but no single genomic variant accounts for more than 0.3% of height variance. At the interface of genetics and environment, epigenetics is expected to contribute to phenotypic variability. IGF1 is an attractive locus to test this hypothesis.Objectives: To quantify the effect of CG methylation of IGF1 promoters on height.<p cla...

Final Height SDS Gain of GH Treated Children with SHOX Deficiency Describing Observational and Clinical Trial Data

Benabbad Imane , Child Christopher , Carel Jean-Claude , Rosilio Myriam

Background: Patients with mutations of the short-stature-homeobox-containing (SHOX) gene likely have impaired growth, with or without a spectrum of skeletal anomalies consistent with mesomelic skeletal dysplasia. In a multinational clinical trial, GH has been shown to increase growth rate and final height (FH).Objective and hypotheses: The aim of this analysis was to describe FH outcome after GH treatment in an observational setting (Genetics and Neuroen...

Safety and Efficacy of Growth Hormone (GH) in Combination with the Gonadotrophin Releasing Hormone Agonist Leuprorelin in Pubertal Children with Idiopathic Short Stature

Benabbad Imane , Tauber Maite , Rosilio Myriam , Paris Emmanuel , Berggren Lovisa , Patel Hiren , Carel Jean-Claude

Background: Due to delays in diagnosis of Idiopathic Short Stature (ISS), puberty has often started when Growth Hormone (GH) is initiated.Objective and hypotheses: To compare GH+leuprorelin (GH+L) with GH alone in patients with ISS and at Tanner puberty stage 2 or 3. We hypothesised that co-administration of GH+L for 2–3 years would delay puberty, prolong GH efficacy and increase adult height.Method: A phase 3, randomised, ope...

The French Experience in Bariatric Surgery ‘Laparoscopic Adjustable Gastric Banding’ in Adolescence

Dabbas Myriam , Khen-Dunlop Naziha , De Filippo Jean Paul , Bougneres Pierre , Goulet Olivier , Revillon Yann

Background: Because the success rate of lifestyle interventions is modest in severely obese adolescents, surgical treatments are now proposed. Laparoscopic adjustable gastric banding (LAGB) represents an attractive treatment with minimal morbidity and reversible procedure.Method: All adolescents were included in prospective longitudinal assessment and entirely managed by a pediatric team. Surgery was proposed only after at least 1-year lifestyle interven...

A Randomised Trial of the Effects of Perinatal Education of Overweight Pregnant Women to Prevent Childhood Overweight: The ETOIG Study

Parat Sophie , Cosson Emmanuel , Baptiste Amandine , Tauber Marie-Therese , Valensi Paul , Bertrand Anne-Marie , Dabbas Myriam , Elie Caroline , Lorenzini Francoise , Negre Veronique

Background: Early-life risk factors of childhood obesity include maternal obesity; smoking, diabetes and high weight gain during pregnancy for the mother; short duration of breastfeeding and poor quality of early feeding in the infants. Perinatal life thus may be a good period for primary prevention.Objective and hypotheses: We aimed to evaluate whether perinatal education of overweight pregnant women would reduce childhood overweight.<p class="abste...

Sulfonylurea Therapy Corrects Hypotonia, Attention Deficits, Improves Complex Neuropsychological Functions and Motricity in Patients with Neonatal Diabetes Secondary to Mutation in Potassium Channel Subunits, Through a CNS Effect

Background: Sulfonylurea therapy (SU) allows a better metabolic control than insulin in patients with neonatal diabetes secondary to mutation in potassium channel subunits (ND-K). Most of these patients have neurological and neuromotor developmental impairments whose changes under SU has not been studied in a systematic and prospective way in a large cohort.Objective and Hypotheses: To demonstrate the beneficial effect of SU on neuropsychological functio...

A case of 46, XX female with short stature, primary ovarian insufficiency and kidney dystopia due to two novel mutations in MCM8 gene

Kvaratskhelia Ekaterine , Tkemaladze Tinatin , Chipashvili Mariam , Jorbenadze Maka , Chitaia Guram

Primary ovarian insufficiency (POI) affects about 1% of females under 40 and represents a major cause of female infertility. Approximately one third of POI are of genetic in origin, including FMR1 premutation, Turner syndrome and approximately 60 other genes, involved in development, hormonal signaling, cell division and survival, immunity, and metabolism. MCM8 is a recently discovered gene that plays an important role in homologous recombination and DNA repair and only up to ...

Rare Disease Registries: Perception of Parents and Young People

Jayasena Arundathi , Muscarella Miriam , Ahmed Faisal

Background: Rare-disease registries are considered to be the key for improving patient care through research and audit. In the field of paediatric endocrinology, the views of parents and affected young people about such registries are unclear.Objective: To conduct a survey to understand the views of parents and young people with rare conditions.Method: A structured questionnaire was completed by two groups of clinic attendees, thos...

The Molecular Causes of Congenital Hypothyroidism: The Scottish experience

Kourime Mariam , Jones Jeremy , Ansari Aisha , Bradley Therese , Mason Avril , Shaikh Guftar

Background: Inherited forms of congenital hypothyroidism (CH) account for approximately one quarter of all causes of CH. These include biosynthetic defects and developmental and morphological abnormalities.Objective: Describe the Scottish experience of genetic testing in CH.Method: Retrospective study over 37 years up to March 2016. Patients were selected on the basis of imaging findings or strong family history of CH.<p class=...
