Background: Silver Russell syndrome (SRS) is a rare imprinting disorder with prenatal and postnatal growth retardation and feeding difficulties. The main molecular causes are loss of methylation of the 11p15.5 imprinting control region (H19/IGF2) and maternal uniparental disomy of chromosome 7. Prader-Willi syndrome (PWS) is a complex neurodevelopmental imprinting disorder with neonatal muscular hypotonia, failure to thrive to insatiable appetite, sho...

Introduction: Action4Diabetes (A4D) is a non-profit UK organisation formed in 2016 that is making sustainable and scalable progress to provide quality Type 1 diabetes (T1D) healthcare in Southeast Asia (SEA). A4D provides comprehensive partnership programmes through a Memorandum of Understanding (MOU) signed with the governments in SEA that guarantees ongoing supplies of free insulin, blood glucose testing, HbA1c tests and hospital emergency funds in low-middl...

Background/Aim: X-linked hypophosphatemia (XLH) is a rare disease caused by inactivating mutations in the phosphate-regulating endopeptidase homolog X-linked (PHEX) gene, characterized by chronic hypophosphatemia. XLH children present with progressive skeletal deformities (leg bowing, waddling gait, poor growth and disproportional short stature), dental abscesses, and craniosynostosis. Most affected children have been treated so far with multiple dail...

Background: Protein intake is crucial for growth. Many inherited metabolic diseases (IMD) require a strict controlled protein diet.Aim: to evaluate growth, pubertal status and body composition in IMD requiring a strict controlled protein diet.Patients & Méthods: Longitudinal follow up cohort study. We recorded data before 4years (early childhood, n=189); betwe...

Background: Type1 diabetes mellitus is increasing worldwide in childhood. Education is an essential part of the package care at diagnosis. It adresses children with newly diagnosed type 1 diabetes and their families and is made by young doctors and paramedical staff (nurses and nutritionnists).Objective: to assess the knowledge of the medical and paramedical staff concerning the global management of type 1 diabetes in ch...

Background: Congenital hypopituitarism (CH), involving deficiencies in one or more anterior pituitary hormones, is rarely observed in combination with severe joint contractures, termed arthrogryposis. Schaaf-Yang syndrome (SHFYNG), which has phenotypic overlap with Prader-Willi syndrome, may be associated with arthrogryposis. L1 syndrome, a group of X-linked disorders including hydrocephalus and spasticity of the lower limbs, may also present with generalized contractures in r...

Background: Glibenclamide has proven to be efficient for patients with neonatal diabetes owing to potassium channel mutations. Anyway its pharmaceutical form is not suitable for young children or infants. The tablets dosage is too high for most infants and must be crushed and diluted before administration. We developed a suspension of glibenclamide (EMA Orphean drug designation january 2016) fitting recommendations of drug administration to allow a precise dosage and designed ...

Background: Primary ovarian insufficiency (POI) affects 1% of women and is associated with significant medical consequences. In approximately 10% of cases, POI presents early with absent puberty or primary amenorrhoea. A genetic cause for POI can be found in up to 30% of women. Identified genes often relate to the complex biological processes occurring in fetal life which underpin normal ovary development and function in later adulthood.Objective: We aim...

Background: Inherited amino-acid metabolism disorders (IAAMDs) require lifelong restriction of natural dietary proteins. Nutritional amino-acid mixtures (AMM) free of the poorly metabolised amino-acids by the enzyme block, improve nutrition. An adequate protein intake is crucial to ensure normal body development, notably during puberty. We aimed to: 1/ describe growth and puberty in IAAMDs 2/ investigate associations linking height, IGF1 and IGFBP3 with AAM an...

Introduction&Aim: Activation of mechanistic target of rapamycin (mTOR) as a major regulator of adipogenesis and lipid accumulation is controlled by upstream regulators hamartin/tuberous sclerosis complex (TSC) 1 and tuberin/TSC2. Hamartin and tuberin form a protein complex that inhibits signal transduction to mTOR. The impact of TSC1 deficiency is not clearly defined in human adipose tissue. We identified a likely pathogenic TSC1 splicing variant in a lipo...
