Background: Congenital hyperinsulinism (CHI) is a rare disease mostly due to loss-of-function mutations of the ABCC8 or KCNJ11 genes, encoding the two subunits of the KATP channel. Gain-of-function mutations in glutamate dehydrogenase 1, encoded by the GLUD1 gene, are the second most common cause of CHI.Objective and hypotheses: The majority of patients with a GLUD1 CHI respond to diazoxide, but little is kn...

Background: PATRO Children is an international, open, longitudinal, non-interventional study of the long-term safety and efficacy of Omnitrope®, a biosimilar recombinant human GH (rhGH).Objective and hypotheses: The primary objective of PATRO Children is to assess long-term safety of Omnitrope® (particularly the diabetogenic potential of GH in short children born small for gestational age, the risk of malignancies, and oth...

Background: PATRO Children is an international, open, longitudinal, non-interventional study designed to evaluate the long-term safety and efficacy of Omnitrope®, a biosimilar recombinant human GH (rhGH).Objective and hypotheses: Long-term safety of Omnitrope® is the primary objective of PATRO Children (particularly the diabetogenic potential of GH in short children born small for gestational age, the risk of malignancies,...

Background: Final results from MEGHA study required by Health French Authorities (HAS).Objective and hypotheses: Objectives are to carry out longitudinal follow-up during maximum 5 years of AGHD patients treated with Saizen, with a description of prescription modalities, demographic and clinical characteristics, patient compliance, product safety, and quality of life.Method: MEGHA is a multicentric study, with prospective follow-up...

Background: The majority of children with short stature are classified as idiopathic short stature. Whole exome sequencing can help identify genetic causes of short stature.Methods: We recruited 10 children with short stature of unknown etiology. We conducted whole exome sequencing of the patients and their family members. We used an analysis pipeline to identify rare nonsynonymous genetic variants that might cause the short stature. All rare allelic var...

Background: Dyshormonogenic hypothyroidism is classically a monogenic disease with recessive inheritance. Thyroid dysgenesis showed a multigenic origin in a mouse model of double-heterozygous deletions of Nkx2.1/Pax8 transcription factor genes, suggesting a possible polygenic nature of certain cases of human hypothyroidism.Objective and Hypotheses: To investigate genetic traits of polygenic involvement in dyshormonogenic hypothyroidism,...

Background: Growth monitoring of apparently healthy children aims at early detection of severe underlying conditions. Strong empirical evidence shows that current practices of growth monitoring are suboptimal. Practice standardisation with validated tools requires answering two questions: Which conditions should be targeted? How should abnormal growth be defined?Objective and hypotheses: To obtain consensus on a short list of priority target conditions o...

Background: Numerous studies focused on the association between hypospadias and Endocrine Disrupting Chemicals (EDC) exposures. The wide variability of phenotypes included in these studies, the absence of comparison groups representative of the populations and the absence of concomitant genetic testing to rule out another cause make the results questionable.Objective and hypotheses: We performed a prospective phenotype-specific analysis of patients with ...

Background: Severe forms of 46,XY DSD with uncertain sex may have a family history (FH) in ~15–20% of cases. On the other side of the DSD spectrum, data regarding isolated hypospadias is sparse and a FH of genital malformation is thought to be less frequent.Objective and hypotheses: The aims of the study were i) to determine the frequency of genital abnormalities in families of isolated hypospadiac boys, ii) to determine whether there is a particula...
