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.

WebPelizaeus-Merzbacher Disease (PMD) and Spastic Paraplegia Type 2 (SPG2) are part of a spectrum of disease with varying severity. There are four general classifications with this spectrum of diseases. In order of severity, these are connatal PMD, classic PMD, complicated SPG2, and pure SPG2. Symptoms of each will be discussed below. Webtials, are of value in early diagnosis of Pelizaeus- Merzbacher disease; brainstem auditory evoked poten- tials with only normal wave I may be a relatively reliable clue suggesting the classic form of Pelizaeus- Merzbacher disease in patients with nystagmus and chronic progressive encephalopathy.

It contains a conserved voltage-sensor domain, shared by a large class of voltage-gated ion channels, but lacks a pore domain. Its primary role is to extrude protons from the cytoplasm upon pH reduction and membrane depolarization. The best-known function of Hv1 is the … hell\\u0027s addiction
