What is H-ABC?

H-ABC (Hypomyelination with Atrophy of the Basal Ganglia and Cerebellum) is an extremely rare genetic disorder that affects brain development and function. It is caused by mutations in the TUBB4A gene, which disrupts the production of myelin—a protective coating that surrounds nerve fibers in the brain and spinal cord.

Children with H-ABC typically experience:

Delays in motor milestones
Abnormal muscle tone (stiffness or floppiness)
Impaired coordination and balance
Speech and communication difficulties
Cognitive delays or intellectual disability
Difficulty with swallowing or feeding
Progressive loss of previously acquired skills

H-ABC is a progressive condition, which means that symptoms may worsen over time. However, supportive therapy can help maintain function, comfort, and quality of life.

Quick Facts:

Caused by mutations in the TUBB4A gene
Involves underdevelopment of brain areas responsible for movement and coordination
Symptoms usually appear in early childhood
No cure exists, but therapy can improve comfort, mobility, and communication

FAQ

Q: How is H-ABC diagnosed?
A: Diagnosis is confirmed through genetic testing, often following brain imaging that reveals specific patterns of hypomyelination and atrophy.

Q: Can my child attend school?
A: With proper support and accommodations, many children can attend special education programs or inclusive classrooms tailored to their needs.

Q: Will therapy help even if the condition is progressive?
A: Yes. Therapy plays a key role in maximizing function, slowing skill regression, and improving comfort and quality of life.
