WebPelizaeus-Merzbacher disease (PMD) is a rare X-linked dysmyelination disorder of the central nervous system (CNS). PMD is caused by mutations in the PLP1 gene located at Xq22 and encoding the major myelin component in CNS, proteolipid protein 1 (PLP1). The disease is clinically heterogeneous. Phenotypes are generally categorized into classic ... WebThe mutations in the gene that can cause the disease lead to an increased or abnormal production of the protein; when this happens, the protein is unable to travel to the cell membrane and form the myelin sheath. Thus, the nervous system functions are impaired and nerve fibers are damaged, leading to the symptoms of Pelizaeus-Merzbacher disease.
