Abstract/OtherAbstract:
Introduction. Pelizaeus-Merzbacher disease (PMD) is caused in most cases by either duplications or point mutations in the PLP1 gene. This disease, a dysmyelinating disorder affecting mainly the central nervous system, has a wide clinical spectrum and its causing mutations act through different molecular mechanisms. Methods. Eighty-eight male patients with leukodystrophy were studied. PLP1 gene analysis was performed by the Multiplex Ligation-dependent Probe Amplification technique (MLPA) and DNA sequencing, and, in duplicated cases of PLP1, gene dosage was completed by using array-CGH. Results. We have identified 21 patients with mutations in the PLP1 gene, including duplications, short and large deletions and several point mutations in our cohort. A customized array-CGH at the Xq22.2 area identified several complex rearrangements within the PLP1 gene region. Conclusions. Mutations found in the PLP1 gene are the cause of PMD in around 20% of the patients in this series.
