**A PRRT2 mutation can cause sudden attacks of abnormal movement (paroxysmal dyskinesia), infant seizures, epilepsy, dystonia, and migraine. Some children outgrow the seizures; the gene does not go away — and many people go years before anyone thinks to test for it.** This is the only knowledge base built for the full PRRT2 spectrum: real science in plain language, written by people who live with this gene.

#### 🔓 Pre-Registry Now Open

<figure><img src="/files/FPAfwNoqGhAWaXh1X75w" alt="Confirmed PRRT2 mutation? You&#x27;ve found your people — become a member of the PRRT2 Foundation."><figcaption></figcaption></figure>

**Have a confirmed PRRT2 diagnosis?** Pre-registering takes a few minutes and makes you a member of the Foundation. **Your name is never shared — only de-identified data.**

This is Step 1. It reserves your place in the full clinical registry now in development, and every person counted makes this community harder to overlook when research funding, partnerships, and clinical trials are decided. Members hear about them first.

**Beyond the textbook:** dysphonia, tics, and the symptoms that get dismissed because they aren't in the standard case description — [we document the wider spectrum too](/exploring-the-wider-spectrum/wider-spectrum.md), where the science is still being written.

#### 🏛️ The PRRT2 Foundation

> **Our Mission:** The PRRT2 Foundation exists to do what a diagnosis alone cannot — explain this condition completely, connect the people living with it, forge the partnerships that accelerate research and expand access to testing, and build the technology that gives every patient a clinical voice.

#### 🤝 You're Not Alone

Living with a PRRT2 mutation isn't only a scientific problem — it's the misdiagnoses, the unanswered questions, and the symptoms nobody could explain. You don't have to navigate it alone.

🔒 **The Community** — our private group, where patients and families ask questions, share what they're going through, and connect with others who understand what this condition actually does to a life.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://www.prrt2.org/readme.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
