X-Linked Hypophosphatemia

X-Linked Hypophosphatemia is not often seen, so not a lot of information is available. It's a condition that is usually diagnosed in children, but being unusual it is often misdiagnosed or in milder cases may not be focused on by the physician or family. 

It usually first shows up as bowed legs in a child and rickets may be diagnosed, but it is often mistaken for nutritional rickets. However, it resists traditional Vitamin D and sunshine therapy, and vitamin D levels are usually normal.  These girls are twins--one having the mutation causing XLH and the other not.  The twin on the left demonstrates the classic signs of bowed legs and slowed growth of a child with XLH, but not all will have the same degree of symptoms.

Specific tests are needed to know what is causing the problem. XLH is rare, so most doctors will never see it. If you or your child has been diagnosed with XLH, or if you think your child might have it, you need to find a doctor and facility experienced in recognizing it and dealing with it. It’s important that it’s treated properly, and that takes someone with XLH experience

Welcome to the XLH Network. If you’re dealing with XLH – also known as X-Linked Hypophosphatemic Rickets, Familial Hypophosphatemia, Vitamin D-Resistant Rickets (VDRR) and even Genetic Rickets – you know the fear of not knowing what to do or where to turn.

We know that fear. We’ve been there. We started this network because our own loved ones have it.  We’re here to help. Please let us.
