Background: Congenital hypothyroidism (CH) affects one in 3000 children at birth. In 65% of cases, CH is due to thyroid dysgenesis (CHDT). For CHDT, there is a family component and therefore genetic. Over the past 20 years, disease-causing mutations in 10 genes have been implicated in CHDT cases (NKX2-1/TTF1, FOXE1/TTF2, NKX2-5, PAX8, GLIS3, NTN1/Netrin-1, JAG1, BOREALIN/CDCA8, TUBB1</...

Background: We found BOREALIN/CDCA8 mutations in patients with Congenital Hypothyroidism and Thyroid Dysgenesis, varying from asymmetric lobes to athyreosis (Carré et al. Hum Mol Genet 2017). Borealin is a major component of the Chromosomal Passenger Complex, an essential regulator of mitosis. We demonstrated a new feature of BOREALIN: involvement in the adhesion and the migration of the thyrocytes.<strong...

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: While the risk for hypoglycemia during acute illness is well described in children with classical congenital adrenal hyperplasia (CAH), there is little evidence for the prevalence of asymptomatic hypoglycemia in CAH. We explored the glucose profile of children with classical CAH by the use of continuous glucose monitoring (CGM).Methods: We conducted an observational study in children aged 1-6 years with a dia...

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...

Background: The SCOPE French retrospective study follows children affected with growth hormone (GH) disorders treated with recombinant human GH (r-hGH) therapy via the easypod® connected injection device for up to 5 years.Aim: To show the results from an interim analysis of the SCOPE study analysing adherence to r-hGH therapy in a real-world setting and its effect on catch-up growth.Met...

Objective: KIGS (Pfizer International Growth Survey) was a large, international database of pediatric patients who received recombinant human growth hormone (rhGH) as prescribed in real-world clinical settings. This analysis evaluated the long-term safety and efficacy data from all participants until KIGS close in 2012.Methods: Children with growth disorders and treated with rhGH (Genotropin® [somatropin]...

Background: Early treatment of neonatal diabetes with sulfonylureas has shown to improve neurodevelopment, beyond the demonstrated efficacy on glycemic control. Several barriers still prevent its use as an early treatment in preterm babies including the limited availability of a suitable galenic form of glibenclamide. Recently, an oral suspension of glibenclamide (Amglidia®) has been approved for use in EU.Methods: W...

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: 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...
