Soft Bones - Finding the key to HPP in Australia

Empowering Australians living with hypophosphatasia

Clear information, local care pathways and a national community for people with HPP, the families beside them, and the clinicians who care for them. Soft Bones Australia's purpose is to connect people affected by HPP right across the country, and we would love for you to join us.

Our mission

Why we exist

Soft Bones Australia exists to raise awareness of hypophosphatasia across Australia, to give patients, families and clinicians information they can trust, and to make sure no Australian has to work out this condition alone.

1

Raise awareness

Make HPP recognised by the public, by GPs and dentists, and by the health system, so that it is found sooner.

2

Inform clearly

Provide accurate, plain-language information for patients, families, clinicians and researchers, written for Australia.

3

Connect people to care

Link Australians to local diagnostic pathways, hospitals, specialists and support services in their own state.

4

Advocate

Push for earlier diagnosis, better access to treatment, and equitable care for a rare condition that is easy to overlook.

5

Build a community

Create a national community so that people living with HPP in Australia can find each other.

6

Be transparent with people

Say plainly what exists in Australia and what does not, rather than leaving families to discover the gaps themselves.

The basics

What is hypophosphatasia?

Hypophosphatasia, or HPP for short, is a rare inherited condition in which the body does not make enough of a working enzyme called alkaline phosphatase. That enzyme is what allows bones and teeth to harden properly.

Without it, minerals do not lock into the skeleton the way they should. Bones can stay soft, break easily and heal slowly. Teeth can loosen and fall out with the roots still attached. Many adults live with deep, persistent bone and muscle pain long before anyone works out why.

HPP is caused by changes in a single gene, ALPL. It affects people across an enormous range, from babies who are critically unwell from birth, to adults whose only sign is losing teeth early, to people who never develop symptoms at all.

Signs worth acting on

When should someone ask about HPP?

  • A blood test showing low alkaline phosphatase (ALP) that stays low on repeat testing
  • Baby teeth lost before age five with the root still attached
  • Repeated foot (metatarsal) stress fractures in an adult
  • Fractures that are slow to heal or do not join
  • Long-standing bone, joint and muscle pain with no clear cause
  • Rickets-like changes in a child whose calcium and vitamin D are normal

Any one of these can have other explanations. Together, or alongside a low ALP, they are worth raising with a GP.

Getting answers

Your pathway to HPP care in Australia

Most Australians reach a diagnosis through the public system, starting with their GP. Here is the route, step by step.

  1. Talk to your GP

    Ask for a total serum alkaline phosphatase (ALP) test, and ask that the result be read against the range for your age and sex, not the adult range.

  2. Confirm the pattern

    A single low reading is not enough. HPP is suspected when ALP is persistently low and other causes have been ruled out. Vitamin B6 and urine tests help confirm it.

  3. Ask for a specialist referral

    Children are usually referred to a paediatric endocrinology or bone service; adults to a bone and mineral or metabolic bone clinic at a major hospital.

  4. Consider genetic testing

    Testing the ALPL gene can confirm the diagnosis and help the rest of the family. It is usually arranged through a clinical genetics service.

Why we exist

Australians with HPP are falling through the gaps

Enzyme replacement therapy exists and is registered in Australia. But Commonwealth funding reaches only the smallest group of patients: babies whose disease begins before six months of age.

Children diagnosed later, and every adult living with HPP, currently have no subsidised pathway to that treatment. Alongside long diagnostic delays and the absence of any Australian data on how many people are affected, that is what we are working to change.

We are looking for Australians living with HPP who are willing to share their story, in their own words and on their own terms.
