A Case of Krabbe Disease Confirmed by Identification of Mutations in the Galactocerbroside beta-galactosidase Gene (GALC)

Krabbe disease is an autosomal recessive disorder involving white matter caused by deficient activity of the lysosomal galactocerebrosidase (GALC). A typical infantile-onset patient shows developmental regression, spasticity, and seizure before 6 months of age, and dies within 2 years. Previously, one case was confirmed by an enzyme test in Korea. We herein report a 2 year-old girl who showed the characteristic clinical course and neuroimaging features of infantile-onset Krabbe disease. Genetic testing identified the compound heterozygote mutations in the GALC gene; NLWE212_215TP/302A.
