Clinical and Para Clinical Features, Effect Oftriptoreline 11.25 Mg Every 3 Months in Patients with Central Precocious Puberty After 6 Months of Treatment

Huynh Thoai Loan , Le Hong Anh , Nguyen Lac Han

Background: Precocious puberty is defined by the development of secondary sexual characteristics before the age of 8 in girls and before the age of 9 in boys. if not diagnosed and treated at an early stage, precocious puberty can compromise final adult height and trigger psychological disturbances. Gonadotropin- releasing hormone analogs (GnRHa) contributes to achievement of target final height by reducing the acceleration of bone maturation.<p class="abst...

Characterization of GNAS miRNAs Targets: Trying to Better Understand the Pathophysiology of Pseudohypoparathyroidism 1B (PHP1B)

Hanna Patrick , Netchine Irene , Le Stunff Catherine , Linglart Agnes

Background: Patients affected with PHP1B are characterized by resistance to PTH which binds to the PTH receptor and activate the cAMP/Gsa signaling pathway. Gsa is encoded by GNAS, a locus subjected to genomic imprinting. PHP1B patients present with abnormal methylation at the maternal A/B promoter and, in some cases, at the other promoters (XLas, GNAS-AS1 and NESP55) of the GNAS locus, likely leading to a decreased express...

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...

A simple model with height and age at start of treatment with recombinant human growth hormone can accurately predict future growth in children with growth disorders

van Dommelen Paula , Arnaud Lilian , Masne Quentin Le , Koledova Ekaterina ,

Background: A growth prediction model would not only allow patients with growth disorders the opportunity to see the expected effect of their recombinant human growth hormone (r hGH) treatment, but also support healthcare professionals to individualise treatment to optimise growth outcomes.Aim: To develop a growth prediction model in children with growth disorders.Patients and Methods: Height and c...

Zhuan-Nan Jiang , Le-le Hou , Zu-lin Liu , Hui Ou , Zhe Meng , Li-na Zhang , Li-yang Liang

Objective: To investigate the clinical features and genetic characteristics of HRAS-associated Costello Syndrome.Method: Characteristics of clinical data and gene mutation of two cases Costello Syndrome in XX hospital were retrospectively analyzed. The related literature was searched by using search terms ‘HRAS’ or ‘Costello Syndrome’.Result: Both patients were presented with mental retardation, growth retardati...

Knock in of the Recurrent R368X Mutation of PRKAR1A that Represses cAMP-dependent Protein Kinase A Activation: A Model of Acrodysostosis Type 1?

Le Stunff Catherine , Tilotta Francoise , Sadoine Jeremy , Le Denmat Dominique , Clauser Eric , Bougneres Pierre , Chaussain Catherine , Silve Caroline

Background: In humans, activating mutations in the PRKAR1A gene cause acrodysostosis1 (ACRDYS1). Two striking features of this rare developmental and skeletal disorder are renal resistance to PTH and chondrodysplasia resulting from the constitutive inhibition of PTHR1/Gsa/AC/cAMP/PKA signaling caused by the PRKAR1A mutations.Objective and hypotheses: Document the consequences of the germline expression of a PRKAR1A mutation causing a dominant repression ...

Microduplication of 3p25.3 and 4p23 Regions in a Patient with Multiple Congenital Anomalies, Congenital Hypothyroidism and Adrenogenital Syndrome

Barreca Massimo , Scavone Maria , Giancotti Laura , Colao Emma , Miniero Roberto

We report the case of a seven-year-old boy, unicogenised child, born at 33w, PN 1,540 Kg, (APGAR 8-10), hospitalized in neonatology unit for 30 days, invasive respiratory assistance was not necessary. At birth evidence of hypospadias with penile incurvation, oval fossa pervia, corpus callosum agenesis. Normal male karyotype. For positivity to screening for IC (in-situ normal thyroid), started L-Thyroxine therapy. When he was six the phenotype showed broad forehead, down-slant...

Longitudinal Development of Adiponectin in Early Childhood and the Influence of Breastfeeding and Essential Fatty Acid Status

Roswall Josefine , Kjellberg Emma , Strandvik Birgitta , Dahlgren Jovanna

Background: Adiponectin is an adipokine related to insulin sensitivity. In adults and older children adiponectin correlates inversely to BMI, insulin resistance, and cardiovascular risk. Less is known about these relationships in early childhood.Objective and hypotheses: To explore the longitudinal development of adiponectin and correlations to early feeding patterns and serum essential fatty acids.Method: 324 term infants were fol...

Serum IGFI Concentration and Growth During Infancy Correlate to Polyunsaturated Fatty Acid Pattern

Dahlgren Jovanna , Kjellberg Emma , Strandvik Birgitta , Roswall Josefine

Background: IGF1 is important for fetal and infant growth and is influenced by nutrition. In young pigs, docosahexaenoic acid (DHA)-enriched food is associated with higher IGF1 levels but studies in human infants are lacking.Aims and objectives: To assess levels of polyunsaturated fatty acids (PUFA) relate to IGF1, birth size and growth during infancy.Methods: The setting was a population-based longitudinal cohort comprising 126 fu...
