Navigating a Canavan Disease Diagnosis

At a Glance

Canavan disease is a rare, inherited genetic leukodystrophy caused by an ASPA gene mutation that damages the brain's white matter. Following a diagnosis, parents should focus on building a specialized care team, managing symptoms with supportive care, and connecting with patient advocacy groups.

Welcome to this resource guide for Canavan disease. We understand that finding yourself on this page means your family has been thrust into an unexpected and overwhelming world. This guide was created to help you navigate the medical system, understand your child’s condition, and empower you to advocate for their best possible care.

A diagnosis of Canavan disease is life-altering. You may be feeling a profound sense of shock, grief, or confusion. Please know that you are not alone. Canavan disease is a rare, inherited genetic disorder, and there is absolutely nothing you did to cause it. You and your partner were silent carriers of a gene mutation, a completely random event of biology.

What is Canavan Disease?
At its core, Canavan disease is a leukodystrophy—a condition that affects the white matter (the insulation) of the brain. A mutation in the ASPA gene prevents the body from making an important enzyme. Without this enzyme, a substance called N-acetylaspartic acid (NAA) builds up in the brain, damaging the white matter and interfering with the brain’s ability to send signals to the body.

This guide translates complex medical information into clear, actionable knowledge so you can build a strong care team, understand treatment options, and focus on what matters most: your child’s comfort and quality of life.

How to Use This Guide

We have broken down the journey into specific, manageable topics. Please read them at your own pace.

Understanding the Basics of Canavan Disease

Symptoms and the Path of Progression

Learn about the symptoms and progression of infantile Canavan disease. Understand early signs like hypotonia and macrocephaly, plus later-stage expectations.

Confirming the Diagnosis: Imaging and Genetics

Learn how Canavan disease is diagnosed. Understand the role of brain MRIs, elevated NAA levels, and ASPA genetic testing in confirming your child's diagnosis.

Subtypes: Infantile vs. Juvenile Forms

Learn about the two main subtypes of Canavan disease: the classic infantile form and the mild juvenile form. Understand symptoms, MRI findings, and expectations.

Managing Symptoms and Supportive Care

Learn how to manage Canavan disease symptoms and improve your child's quality of life. Discover supportive care options, from seizure control to feeding tubes.

The Horizon of Hope: Clinical Trials and Gene Therapy

Learn about the latest clinical trials and gene therapy options for Canavan disease. Understand how MYR-101 and BBP-812 work to replace the faulty ASPA gene.

Building Your Child's Care Team

Learn how to build a medical care team for a child with Canavan disease. Understand the essential roles of neurologists, pulmonologists, and other specialists.

Daily Life and Quality of Care

Learn how to manage daily life with Canavan disease. Discover practical care tips for hypotonia and macrocephaly, symptom tracking, and caregiver support.

Take a deep breath. You are taking the first step toward becoming your child’s greatest advocate.

Common questions in this guide

What is Canavan disease?

Canavan disease is a rare, inherited genetic disorder classified as a leukodystrophy. It affects the white matter of the brain, interfering with the brain's ability to properly send signals to the body.

What causes Canavan disease?

It is caused by a mutation in the ASPA gene that prevents the body from making an important enzyme. Both parents must be silent carriers of this genetic mutation for their child to inherit the condition.

How does Canavan disease damage the brain?

Because the body cannot produce a necessary enzyme, a substance called N-acetylaspartic acid (NAA) builds up in the brain. This toxic buildup damages the white matter, or the insulation, of the brain.

What are the first steps after a Canavan diagnosis?

Your immediate priorities should be identifying a main coordinator or 'quarterback' for your child's medical team and addressing any urgent symptoms. Connecting with local or national patient advocacy groups is also highly recommended.

Curated prompts to bring to your next appointment.

1.Based on my child's age and symptoms, what should be our immediate next steps for their care plan?
2.Who will act as the 'quarterback' or main coordinator for my child's medical team?
3.Are there any local or national patient advocacy groups you recommend we connect with immediately?
