Abstract
Pelizaeus-Merzbacher disease (PMD) is a genomic disorder that is caused by altered dosage of a single gene, proteolipid protein 1 (itPLP1). Either duplication or deletion of itPLP1-containing genomic regions on chromosome Xq22.2 results in a severe leukodystrophy characterized by deficits of myelination in the central nervous system (itCNS). In this chapter, the molecular and genomic mechanisms for rearrangements causing PMD are reviewed, emphasizing differences in comparison to Charcot-Marie-Tooth disease type 1A (CMT1A) and hereditary neuropathy with liability to pressure palsies (HNPP)
