Background: GLI2 is a zinc-finger transcription factor of the SHH signaling pathway, expressed during ventral forebrain and pituitary development. GLI2 mutations account for microforms of dominant holoprosencephaly. So far, only 15 unambiguous mutations were found in hypopituitarism –essentially combined pituitary hormone deficiency (CPHD)– frequently associated with holoprosencephaly-like malformations and/or polydactyly.Objective and...

Background: In patients with HC due to N540K FGFR3 mutations, adult height ranges 138–155 cm (men) and 128–145 cm in women. We have previously reported that a mean 0.075 μg/k.d rGH dose could allow a gain of 1.9 S.D. of height over 6.1 year and could reduce body disproportion in 6 young patients (Journal of Pediatrics 2012).Objectives: To confirm these results and extend observation of rGH effects.<p class="abst...

Recent data pertaining to the bio-psychosocial development of the adolescent, particularly from a neurobiological perspective, indicate that both at the level of individual care and of preventive strategies, the concepts, languages and strategies used should be adapted to the maturity of the adolescents. Moreover, since around thirty years under the era of AIDS, the medical scientific literature tackling the issue of adolescent sexuality and sexual behavior has sadly focused e...

Global Pediatric Endocrinology and Diabetes (GPED) aims at addressing needs that are common to all societies and is not intended to duplicate the specific societies’ activities. GPED’s website (www.globalpedendo.org) allows for registration of members as well as for a search function.Specific existing and potential projects include:i) Preventing redundancy of resources: developme...

Background: Early life stress (ELS) are known to have a deleterious impact on health, but their potential long-term consequences on mortality remain to be assessed. World War 1 (WW1) has caused major stress and bereavement to millions of European mothers.Objectives and hypotheses: To compare the effects of a maternal stress occurring during intra uterine or in postnatal life upon long-term mortality.Patients: Thanks to recently dig...

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...

Background: Gestational exposure to endocrine disrupting chemicals (EDCs) can impact the control of sexual differentiation by altering the hormonal environment of the foetus. Prenatal exposure to BPA, for instance could lead to disorders of sexual development. At the interface between the mother and the foetus, the placenta plays a key role in foetal programming and responds to environmental stressors in a sex specific manner. Epigenetics has appeared to be a key mechanism for...

Background: The diagnosis of Growth Hormone Deficiency (GHD) involves the use of GH stimulation tests that require day case admission, multiple blood sampling and are associated with significant adverse effects.Aim: To assess the utility of gene expression (GE) profiling and candidate SNP analysis for the diagnosis of and classification of GHD.Method: Pre-pubertal treatment-naïve children with GHD (n=98) were enrolled from the...

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...

Background: TransCon hGH is a long-acting prodrug of recombinant human growth hormone (hGH) that releases fully active unmodified hGH into the blood compartment. This presentation will detail the final safety and efficacy results of TransCon hGH in a Phase 2 study in children with GHD over a treatment period of six months.Objective and hypotheses: The objective of this Phase 2 study in GHD was to investigate 1) safety and tolerability, 2) pharmacokinetic...
