Pelizaeus-Merzbacher disease, a rare genetic disorder affecting myelination, can mimic multiple sclerosis (MS) in female carriers. PLP1 gene mutation testing is recommended for women with unexplained spastic paraparesis and cognitive decline.
Area of Science:
- Neurogenetics
- Demyelinating Diseases
- Molecular Neurology
Background:
- Single gene disorders can be misdiagnosed as multiple sclerosis (MS).
- Pelizaeus-Merzbacher disease and spastic paraplegia type 2 are allelic X-linked disorders caused by PLP1 mutations, affecting central nervous system myelination.
- Female carriers of PLP1 mutations may exhibit neurological symptoms.
