Musculoskeletal toll ‘may start at 20’ in rare disease

Musculoskeletal problems can start as early as age 20 and gradually accumulate in adults with X-linked hypophosphataemia, a study shows.
The rare inherited disorder is characterised by low serum phosphate, leading to lifelong and progressive musculoskeletal problems.
UK researchers evaluated data on 336 adults with X-linked hypophosphataemia (XLH), including 127 participating in a clinical trial, 209 who completed an online survey, and a subgroup of the online survey participants with pain comparable to the clinical trial subjects.
In all three groups, 43%-47% had a history of fracture, with the proportions increasing with age.
