A new polymorphism in the proteolipid protein (PLP1) gene and its use for carrier detection of PLP1 gene duplication in Pelizaeus-Merzbacher disease.
Pelizaeus Merzbacher Disease (PMD) is an X-linked recessive dysmyelinating disorder of the central nervous system. Most patients have point mutations in exons of the proteolipid protein (PLP1) gene or duplication of a genomic region that includes the PLP1 gene. We identified a common MspI polymorphism in intron 1 of the PLP1 gene and used it to determine carrier status for PLP1 gene duplication in PMD by using a quantitative PCR approach.
