Abstract excerpt
X-linked hypophosphatemia (XLH) is a rare, genetically determined disorder of phosphate metabolism, most commonly caused by mutations in the PHEX gene. These mutations lead to overexpression of the phosphaturic hormone FGF23, resulting in renal phosphate wasting and impaired bone mineralization. In up to 16% of clinically diagnosed cases, no causative variant can be identified using standard sequencing...
