<abstract xmlns="http://www.w3.org/1999/xhtml"> Krabbe disease (KD) (globoid cell leukodystrophy) is a degenerative, lysosomal storage disease, caused by a severe loss of galactocerebrosidase (GALC) enzymatic activity. The inheritance is autosomal recessive. KD affects the white matter of the central and peripheral nervous systems. We present a 3 year old boy in whom the disease had an ‘infantile’ or ‘classic’ presentation, with spasticity, irritability, and developmental delay. In addition the boy showed progressive severe motor and mental deterioration, difficulties in swallowing and decerebration. Molecular analysis revealed that the child is a compound heterozygote: p.Asp187Val (c.560A>T) and p.Ile250Thr (c.749T>C). The father was the carrier of p.Asp187Val (c.560A>T), while the mother was the carrier of the p.Ile250Thr (c.749T>C) in exon 6 of the GALC gene.
