    Pelizaeus-Merzbacher disease (PMD) is a leukodystrophy associated with mutations in the proteolipid protein (PLP) gene. Jimpy is a mouse model of human PMD, and a splice site mutation in Jimpy causes the deletion of exon 5 from the PLP mRNA, producing a truncated form of PLP. We describe a de novo point mutation at the 5' splice donor site of exon 5 in a 17-year-old male with PMD, which results in the skipping of 42 base pairs of exon 5. The mutation removes only 14 amino acids in-frame of PLP. This is a novel splice donor site mutation in the human PLP gene. Moreover, the results indicate that the 14-amino acid deletion in the PLP is responsible for oligodendrocyte cell death and the development of PMD.
