Introduction: Achondroplasia is caused by a pathogenic mutation in the FGFR3 gene, leading to impaired endochondral bone growth and multiple medical complications. Vosoritide, a modified recombinant human C-type natriuretic peptide (rhCNP), was approved by the European Medicines Agency (EMA) in August 2021 for treating genetically confirmed achondroplasia in patients aged ≥2 years until closure of epiphyses. Acorn is the first treatment-based registry for a...

Introduction: IPEX Syndrome (Immune dysregulation, Polyendocrinopathy, Enteropathy, X-linked) is characterized by mutations in the Forkhead BoxP3 (FOXP3) transcription factor, leading to autoimmunity in various organs starting in the perinatal period. This syndrome manifests with proliferative lesions in the thyroid gland, gastrointestinal system, skin, and other organs. We report a case of a 4-month-old male with neonatal diabetes, resistant thrombocytopenia,...

Background: Data on FGF23-related Hypophosphatemic rickets (HR)/osteomalacia in GCC are sparse. This observational registry aims to collect data on the treatment, disease burden, progression, and long-term outcomes among patients with FGF23-related HR/osteomalacia in GCC, effectiveness and safety of treatments, quality of life and healthcare resource utilization.Methods: This multicenter registry aims to enroll 200 patie...

Introduction: The European Registries for Rare Endocrine Conditions (EuRRECa) was created in collaboration with the European Reference Network on Rare Endocrine Conditions (Endo-ERN), the European Society for Paediatric Endocrinology and the European Society of Endocrinology to support the needs of the endocrine community.Aim: To describe the patient population and data entered in the EuRRECa Core Registry between June 2...

Background: EuRRECa (European Registries for Rare Endocrine Conditions) is a new project incorporating the development of a core endocrine registry and the development of an e-reporting programme for rare endocrine conditions (e-REC) that are covered within Endo-ERN (https://eurreca.net/e-rec/).Methods: 24 Endo-ERN centres within 12 countries participated in a pilot phase of e-REC...

Background: Registries are of key importance for a centre of expertise. Endo-ERN consists of 71 reference centres (RCs) that cover several groups of rare endocrine conditions within 8 themes (www.endo-ern.eu). It is unclear if awareness, participation and availability of registries is uniform for all conditions within Endo-ERN.Objective: To determine the extent of engagement in registries of Endo-ERN members.<p cl...

Background: Gordon Holmes syndrome (GHS) is characterized by cerebellar ataxia/atrophy and normosmic hypogonadotropic hypogonadism (nHH). The underlying pathophysiology of this combined neurodegeneration and nHH remains unknown.Patients and methods: We studied a cohort of multiplex families with GHS through autozygosity mapping and whole exome sequencing.Results: We identified patients from three independent families carrying loss-...

Introduction: Sanjad-Sakati-Syndrome (SSS), or hypoparathyroidism-retardation-dysmorphism syndrome (HRDS), is primarily observed in individuals of Middle Eastern descent due to a recessive founder mutation in exon 3 of the TBCE gene. Little is known about disease evolution, endocrine features, management and cause of early death.Aim: To gain better understanding of growth, full phenotypic spectrum, endocrine fea...

Introduction: Prader-Willi syndrome (PWS) is a genetic condition characterized by a complex hypothalamic dysregulation of the growth hormone/insulin-like growth factor (GH/IGF) axis, short stature, obesity, reduced muscle mass and impaired quality of life. The risk of obstructive sleep apnea (OSA), central hypoventilation (CHV) and sleep-disordered breathing (SDB) are the major causes of morbidity and mortality in these patients....

Introduction: In cases of disorder of sex development (DSD), the change between the gender assigned at birth and the individual's chosen gender identity can occur especially after puberty.Aim: was to determine the relationship between genetic sex, gender assigned at birth and gender identity, and the importance of molecular diagnosis.Method:154patients older than 14years of ag...
