About Krabbe Disease
Krabbe Disease is a lysosomal lipid storage disorder resulting from mutations in the GALC gene encoding galactocerebrosidase. This enzyme normally catalyzes the breakdown of galactocerebroside, a major galactose-containing lipid component of myelin. GALC deficiency leads to accumulation of galactocerebroside and its toxic metabolite psychosine in oligodendrocytes, Schwann cells, and macrophages. Psychosine accumulation is particularly neurotoxic, triggering cell death through multiple pathways including apoptosis, autophagy dysfunction, and oxidative stress. This results in progressive demyelination of both central and peripheral nervous systems.
The infantile form, accounting for 90% of Krabbe cases, is the most severe. It typically begins between 3-6 months of age with developmental regression, loss of developmental milestones, progressive spasticity, and loss of visual and hearing function. Without treatment, infantile Krabbe is rapidly progressive and fatal by age 2-4 years. Late-infantile forms show delayed but still progressive neurological decline. Juvenile and adult forms progress more slowly but still cause significant disability. Diagnosis relies on demonstrating reduced GALC enzyme activity in leukocytes or fibroblasts, elevated lyso-galactosylceramide levels, and genetic testing. MRI shows progressive white matter changes and demyelination.
Common Symptoms of Krabbe Disease
Recognizing the signs of Krabbe Disease early can lead to faster diagnosis and better outcomes. Symptoms may vary in severity from person to person. If you or a loved one are experiencing any of the following, consider speaking with a specialist.
- Infantile form: developmental regression, irritability, and spasticity from 3-6 months of age
- Peripheral neuropathy with loss of sensation
- Progressive visual loss and blindness
- Seizures starting in infancy or childhood
- Severe developmental delays and intellectual disability
- Progressive loss of motor function leading to paralysis
Who Krabbe Disease Affects
Most common presentation is infantile-onset form appearing in first 3-6 months of life with rapid progression. Late-infantile form appears between 6 months and 3 years.
Juvenile form appears between 3 and 30 years with slower progression. Adult-onset forms are rare. Affects males and females equally. Autosomal recessive inheritance. Higher prevalence in certain populations including Scandinavian ancestry.
