For children 6 months or older,
Early diagnosis and treatment of XLH can help manage your child’s symptoms
For children 6 months and older with XLH, early diagnosis and treatment is important to help manage low phosphorus levels in the blood, rickets, and delayed growth.
XLH is a rare, lifelong, genetic disease that can get worse over time when left untreated.
XLH affects up to 1 in 20,000 people and can impact the bones and muscles of both children and adults.
Children with XLH don’t have enough phosphorus in their bodies. Phosphorus is a mineral that is important to the health of bones and muscles. When phosphorus levels are too low, it is called hypophosphatemia.
This can cause something called rickets, a condition where growing bone weakens over time, leading to lower limb abnormalities.
Did you know? XLH often runs in the family
XLH is a hereditary condition. People can inherit XLH from either their father or mother. If one member of the family has XLH, there is a good chance that other members may have it, too.

Over time, bone weakening can also lead to:
