Splicing mutations of GALC in adult patient with adult-onset Krabbe disease: case report and review of literature

Krabbe disease (KD) is classed as the lysosomal storage disease with mutations in the galactosylceramidase (GALC) gene, and commonly showed as autosomal recessive pattern with 30-kb deletion in infantile subtype. In this case, we report a 39-years adult-onset KD (AOKD) patient with multiple sclerosis-like symptoms and neuroimaging changes. She carries the heterozygous mutations in GALC included a missense mutation of c.1901T>C from her mother, and a splicing mutation of c.908+5G>A from her father. The splicing mutations in KD are reviewed and confirmed that c.908+5G>A is a novel splicing mutation in AOKD.
