WebPelizaeus-Merzbacher disease (PMD; MIM 312080) is classified as a dysmyelinating or hypomyelinating disorder, in which normal myelination never occurs, as opposed to a demyelinating disorder, in which normal myelin is later destroyed [ 7,8 ]. PMD is caused by pathogenic variants of the gene for proteolipid protein 1 ( PLP1; MIM 300401).
WebDec 2, 2024 · The X chromosome gene PLP1 encodes myelin proteolipid protein (PLP), the most prevalent protein in the myelin sheath surrounding the central nervous system. X-linked dysmyelinating disorders such as Pelizaeus–Merzbacher disease (PMD) or spastic paraplegia type 2 (SPG2) are typically caused by point mutations in PLP1. Nevertheless, … WebIn the less severe classic form of PMD, high T1 signal is usually seen in the posterior limb of the internal capsule, as well as in the optical radiations and corona radiata, all suggesting a degree of developmentally-appropriate myelination. ...
