Context: The transition period between pediatric and adult medicine is associated with poor patient outcomes and an important number of patients lost to follow up. Intervention exist but the few published randomized trials do not allow to study long-term patient outcomes nor intervention sustainability in time. Objective. Describe the cohort of patients in adult care who benefit from a new transition program based on case management approach, its activity and follow-up outcome...

Congenital hypothyroidism (CH), occurs with a frequency of one in 3–4000 and is most commonly due (85%) to complete or partial failure of thyroid gland development (dysgenesis). Several transcription factors (TTF-1/Nkx2.1, TTF-2/FOXE1, PAX-8), are highly expressed in the developing rodent thyroid. We first showed that the FKHL15 gene is the human homologue of TTF-2, identifying a homozygous, loss-of-function, mutation in two siblings with CH, thyroid agenesis, clef...

BackgroundFeatures of Prader-Willi syndrome (PWS) overlap with features of growth hormone (GH) deficiency, like small hands and feet, short stature, increased body fat and low muscle mass and strength. In children with PWS, GH treatment improves physical health, cognition and quality of life (QoL). GH treatment is standard of care in PWS children, but in adults this is not the case. A systematic review and meta-analysis was conducted to provide a concise...

Background: Previously, we identified a novel gene, BOREALIN/CDCA8 in congenital hypothyroidism. Patients with BOREALIN mutations had thyroid dysgenesis, 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.<...

Introduction: There are contradictory results concerning bone mineral density status in adult patients with congenital adrenal hyperplasia. To resolve this issue, we hypothesized that there could be a correlation between BMD and a total cumulative glucocorticoid dose from the diagnosis in early infancy to adulthood. We then conducted a retrospective in a referral centers for CAH. Thirty-eight adult patients (28 women, 10 men, aged 16–39 years) suffering from CAH and treat...

Background: Constitutional duplications of the PRKACA gene locus have been described as responsible for adrenal Cushing’s disease.The objective here was to evaluate the results of its systematic screening in bilateral adrenal nodular disease and to specify the associated phenotype.Methods: Between 2020 and 2023, 440 consecutive index cases with macronodular or micronodular adrenal hyperplasia or Carney Complex (CNC) w...

Background: Congenital hypogonadotropic hypogonadism (CHH) is characterized by absent puberty and infertility due to a lack of GnRH secretion/action. In addition, patients exhibit variable non-reproductive phenotypes such as anosmia, cleft palate, synkinesia, and others. As many as 10% of CHH patients harbor mutations in FGFR1; this group is enriched for skeletal anomalies. We report here a novel CHH-associated skeletal phenotype, split hand/foot malformation (SHFM), ...
