Indels are highly abundant in human genomes and have contributed massively to genome evolution. However, the role of indels and their underlined mechanisms of mutagenesis in Mendelian disorders still needs to be appreciated. To explore the contribution of indels in a monogenic disorder, we analyzed all indels already described in the AR gene, including three novel indels found in our cohort. We analyzed the indel distribution through the AR coding region, compared wit...

Background: In monogenic diabetes due to KCNJ11 and ABCC8 mutations that impair KATP- channel function, sulphonylureas improve long-term glycaemic control. Although KATP channels are extensively expressed in the brain, the effect of sulphonylureas on neurological function has varied widely. We evaluated published evidence about potential effects of sulphonylureas on neurological features, especially epilepsy, cognition, motor function and muscular tone, visuo-...

Background: Severe primary insulin-growth factor-1 (IGF1) deficiency (SPIGF1D) is a rare cause of short stature. Diagnosis is based on low basal IGF1 concentration, short stature, normal or elevated growth hormone concentrations and absence of any secondary causes of growth failure. Thanks to advances in next-generation sequencing (NGS) technologies, genetic etiology of SPIGF1D is expanding.Objectives: • Identify th...

Introduction: Most patients with endocrine diseases diagnosed during childhood require long-term continuity of care. A lack of regular medical follow-up visits may be associated with impaired long-term health outcomes, with greater risks of morbidity and mortality. The importance and challenges of the transition from pediatric to adult healthcare are well recognized, but few studies have considered loss to follow-up during pediatric care. We investigated the p...

Background: Thymus transplantation is undertaken for conditions associated with severe immunodeficiency. These comprise a number of genetic and syndromic associations including 22q deletion syndrome, CHARGE association, diabetic embryopathy, and other rarer conditions. Autoimmune thyroid dysfunctions (Hashimoto's thyroiditis and Graves' Disease) are described in the literature as the most common autoimmune disease after thymic transplant.<p class="...

Background: Thymus transplantation is undertaken for conditions associated with severe immunodeficiency. These comprise a number of genetic and syndromic associations including 22q deletion syndrome, CHARGE association, diabetic embryopathy, and other rarer conditions. These conditions may also be associated with hypoparathyroidism and patients are therefore at risk of severe hypocalcaemia. There are no published guidelines for calcium replacement in these patients during the ...

Background: Non-idiopathic central precocious puberty (CPP) is caused by acquired or congenital hypothalamic lesions visible on magnetic resonance imaging (MRI), or associated with various complex genetic and/or syndromic disorders without visible lesions on MRI. We investigated the different types and prevalences of non-isolated CPP phenotypes in a large group of consecutive patients with CPP.Methods: This observational cohort study included all patient...

Background: Klinefelter syndrome (KFS) is a sex chromosomal disorder characterised by hypogonadism, progressive testicular failure, gynaecomastia and learning difficulties. Genital anomalies are rarely observed in KFS. Androgen insensitivity has been previously postulated, but not proven to cause genital ambiguity in KFS. Androgen receptor (AR) gene defects are reported in AIS, but have not been reported in children with KFS with mild hypospadias. We describe a novel ...

Background: Neonates born from mothers with Graves’ disease are at risk to develop hyperthyroidism due to placental transmission of TSH-receptor antibodies. Neonatal hyperthyroidism should be effectively diagnosed and treated to prevent severe complications of this disease (cardiac symptoms, poor weight gain, severe neurological manifestations).Objectives: To describe the post-natal follow-up of neonates born from women with Graves’ disease.</p...

Background: Vaginal agenesis (VA) in MRKH syndrome can be managed either by surgery or autodilatations.Objective and hypotheses: To compare different managements of MRKH-VA in terms of quality of life, sexual function, anatomical results and complications.Method: National Multicentric observationnal study including 130 patients older than 18, at least one year after completing VA management, from October 2012 to April 2015. 84 had ...
