Background: X-linked hypophosphatemia (XLH) is a rare, progressive, phosphate-wasting disorder that compromises skeletal development in childhood. The international XLH registry (NCT03193476) is a non-interventional, observational, real-world data collection programme established in August 2017 in Europe and Israel, with enrolment open to patients of any age with XLH.Objectives: To describe real-world registry data on HR...

Background: XLH is a rare, genetic, life-long disease caused by PHEX pathogenic variants. It is associated with progressive accumulation of musculoskeletal features and symptoms that evolve across the patient’s lifetime if untreated. Although the disease is well characterised in children and adults, there are limited data describing the health outcomes and experiences of adolescents, particularly at end of skeletal growth (EOSG), a crucial phase during t...

Introduction: X-linked hypophosphatemia (XLH) is a rare, progressive, genetic disorder causing phosphate wasting; hence symptoms in children include impaired growth, lower limb deformities, chronic pain and impaired physical function. Health-related quality of life (HRQoL) of patients with XLH on conventional therapy is lower than that of the general population. Burosumab has been shown to improve HRQoL in younger children and adults, but its effects in adoles...
