World HPP Day 2025

Is There a HIPPO in the Room?

World HPP Day, on October 30th, is a time for the HPP community to come together and raise awareness about hypophosphatasia. Whether you’re living with HPP, a family member or friend, a caregiver, a researcher, or a healthcare professional, join us in fulfilling our mission.

This year, we celebrate the progress we’ve made but recognize how far we still have to go in understanding the impact of low alkaline phosphatase in the body. 1:200 people are estimated to be carriers of HPP and now we know that carriers can actually have symptoms of HPP. That means in the US alone, by these estimates, there could be as many as 1.6 million people who have an ALPL mutation! Across the world, if those numbers are accurate, that’s 40 million people globally! We may have soft bones, but our spirit to make a difference is stronger. We will not give up.

This means despite our efforts, HPP is still grossly underdiagnosed. The good news is that alkaline phosphatase testing is readily available in simple blood panels; however, low levels are being overlooked by health care professionals. Patients may present with symptoms, but unless they present with life-threatening forms of HPP, they are easily overlooked. There’s an elephant in the room – or in HPP we say a HIPPO in the room – that is not being addressed. We need the HIPPO to be seen. Instead, we have patients being misdiagnosed with other conditions such as osteoarthritis, osteoporosis, fibromyalgia, chronic fatigue syndrome and other conditions. 

The more patients who are diagnosed with HPP, the more power we have as an HPP community. If those estimates are correct, HPP may not be as rare as we think. 

Raising Awareness

There are many ways you can help us spread the word and ensure the HIPPO IN THE ROOM isn’t overlooked. Below you will find social media content, and suggestions for other ways for you to share your story. But the most important part is that we share that if you have low ALP, think HPP!
