Insight into Natural History and Phenotype in Untreated Adults with X-Linked Hypophosphatemia.
Adults with untreated X-linked hypophosphatemia face significant physical and quality-of-life challenges, clarifying the real need for available treatments.
In the first comprehensive natural history study of untreated adult X-linked hypophosphatemia (n=52), the majority demonstrated disproportionate short stature and skeletal deformities, with pseudofractures in 33%, overweight/obesity in 87%, and severely compromised quality of life. These findings establish the substantial ongoing disease burden in untreated adults and provide phenotypic reference data for burosumab trial design and rare disease registry development.
