Background: Non-classical congenital adrenal hyperplasia (NCCAH) may present during childhood, adolescence or even adulthood with various degrees of hyperandrogenism. Diagnosis is established through tetracosactide (Synacthen®) test and genotyping. Cortisol insufficiency has rarely been described in NCCAH.Objective and hypotheses: To describe cortisol response to tetracosactide test in NCCAH patients.Method: Retrosp...

Background: Short stature may be a source of social and affective stress in children and their parents, and thus impact negatively on their quality of life (QoL). Treatment by GH may improve QoL through normalisation of height.Objective: To evaluate height-specific QoL in short stature children after 1 year of GH treatment.Methods: Prospective study. Inclusion criteria were: having started GH treatment at Hôpital Necker-Enfant...

Background: Severe primary insulin-growth factor-1 (IGF1) deficiency (SPIGF1D) is a rare cause of growth delay. The diagnostic criteria include age- and sex-dependent low basal IGF1 concentration (<2.5th percentile), height SDS < -3SDS, absence of growth hormone deficiency and of any secondary causes of growth failure.Objectives: 1) Report the growth pattern and pubertal status 2) Identify the molecula...

Background: short stature can lead to emotional and social stress in children and adolescents. We previously demonstrated in a cohort of 74 children that a one-year growth hormone treatment (GHT) is associated with a significant improvement of quality of life (QoL) especially on emotional and social scales, both in general (PedsQL 4.0) and height-specific (QoLiSSY) questionnaires. Whether this improvement is sustained until adult height remains to be documente...

Introduction: Congenital Lipoid Adrenal Hyperplasia (CLAH) is a severe deficiency of adrenal and gonadal steroidogenesis, caused by mutations in the StAR gene and the accumulation of cholesterol in the outer mitochondrial membrane due to steroidogenic acute regulatory protein (StAR) deficiency. Affected patients present peripheral adrenal insufficiency with early onset, and variable phenotypes at the age of puberty.Objective of o...

Background: Severe primary insulin-growth factor-1 (IGF-1) deficiency (SPIGF1D) is a rare cause of growth retardation. Diagnostic criteria include age- and sex-dependent low basal IGF-1 levels (<2.5th percentile), height ≤ -3SDS, absence of growth hormone deficiency and of any secondary causes of growth failure.Objectives: Description of pubertal onset and growth spurt, data on adult or near-adult-he...

Background: Abnormalities in the hypothalamo-pituitary-gonadal axis have been reported in Noonan syndrome (NS) males but few data are available in female patients. Objective: The aim of this retrospective study was to evaluate the gonadal function of female patients with NS and to look for genotype-phenotype correlations. Patients and Methods: The study population included 19 girls/adolescents with a genetically confirmed diagnosis of NS and with available cli...

Background: Severe primary insulin-growth factor-1 (IGF1) deficiency (SPIGF1D) is a rare cause of growth retardation. Diagnostic criteria include age- and sex-dependent low basal IGF1 levels (<2.5th percentile), height ≤ −3SDS, absence of growth hormone (GH) deficiency and of any secondary causes of growth failure.Objectives: Phenotypic description, follow-up and molecular studies in a cohort of patients diagnosed with growth 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...

Background: Neonatal hyperinsulinism is the most frequent cause of neonatal recurrent hypoglycaemia. The persistent form can be explained by mutations of genes involved in beta cell function, whereas the transient form can occur in case of prematurity, low birth weight, macrosomia, perinatal hypoxia, and maternal diabetes.Objective and hypotheses: As we observed an increase in the incidence of neonatal hyperinsulinism, we hypothesized that potential mate...
