STXBP1 Australia

Relentless seizures. Words that never come. Years for a first step. Help us find a cure.

For many children with an STXBP1 disorder, this is everyday life. There is no cure yet, and no treatment that targets the cause. Australian research can change that, and your gift funds it.

Understanding the condition

What is an STXBP1 disorder?

Everyone has the STXBP1 gene. It holds the instructions for making the STXBP1 protein, which nerve cells need to release the chemical messengers that let them talk to each other.

In an STXBP1 disorder, a change (mutation) in one copy of the gene means too little working protein is made, and the brain can't communicate as it should. In most cases the change happens spontaneously and isn't inherited from either parent.

  • 1 in 30,000 people are estimated to be affected. STXBP1 is one of the five most common genes behind severe childhood epilepsies.
  • What families live with

    Seizures, intellectual disability, low muscle tone, speech impairment (often non-speaking) and movement disorders.

  • No cure yet

    Today's care manages symptoms only. There is no treatment that targets the cause, which is why research matters.

Why it matters

Every step is hard-won

For a child with an STXBP1 disorder, standing, taking a step or saying "Mum" can take years of therapy (if ever). Families call these moments inch-stones, and they celebrate every single one.

"Sometimes progress isn't loud. Sometimes it's measured in inchstones."

There is still no cure and no treatment that targets the cause. Research is how we change that, and it's funded by people like you.

The reality of seizures

For some children, seizures never let up

Most children with an STXBP1 disorder have epilepsy. For some, the seizures keep coming despite medication, day and night, week after week. This is one family's reality.

Seizures start in the first year
89%
have their first seizure before their first birthday
Seizures start as a newborn
47%
start having seizures in their first month of life

"Our daughter had more than 1,000 seizures before she was six months old. We lived in a constant state of fight or flight: never fully asleep, always listening for the next one. Every seizure felt like an emergency, and they never stopped coming."

Those first months are when a baby's brain is developing faster than at any other time in life. For a child with an STXBP1 disorder, they can instead be spent in hospital, with EEGs and one medication change after another, while parents count seizures instead of milestones.

Better treatments only come from research. Help us find them faster.

Annabelle's story

Annabelle could run, climb and feed herself. Then, at four, she began to lose those skills. Today she can no longer walk and needs full assistance with every part of her life. Her family share the long road to an STXBP1 diagnosis, and why research matters.
