The connatal form is the most severe form presenting, since birth, with hypotonia, nystagmus, respiratory distress, and stridor, with subsequent motor and cognitive delay and spastic quadriparesis. [orpha.net]
A male neonate presented with severe respiratory distress that required tracheostomy. [nature.com]
The congenital form has similar characteristics but presents early in infancy and features rapid disease progression. Transitional and adult subtypes have a later onset and less severe symptomatology. [hon.ch]

Treatment Edit There is no cure for PMD, nor is there a standard course of treatment. Treatment, which is symptomatic and supportive, may include medication for seizures and spasticity. [psychology.wikia.com]
Treatment [ edit ] This section needs to be updated. [en.wikipedia.org]
Treatment is symptomatic and supportive. Also called familial centrolobar sclerosis, Merzbacher-Pelizaeus disease, Pelizaeus-Merzbacher sclerosis. Merzbacher, Ludwig, German physician in Argentina, 1875-1942. [medical-dictionary.thefreedictionary.com]
Prognosis
Prognosis PMD has a progressive course that varies depending on the phenotype. In the most moderate forms, life expectancy is quite long and the disease progresses slowly after adolescence. [orpha.net]
The prognosis for those with Pelizaeus-Merzbacher disease is highly variable, with children with the most severe form (so-called connatal) usually not surviving to adolescence, but survival into the sixth or even seventh decades is possible, especially [psychology.wikia.com]
Regular evaluations by physical medicine and rehabilitation, orthopedic, developmental, and neurological specialists should be made to ensure optimal therapy and educational resources. [ citation needed ] Prognosis is highly variable: patients with the [en.wikipedia.org]
At present an exact diagnosis is seldom important with regard to therapy but it may be invaluable when genetic advice is requested by the parents, and in prognosis. [docslide.us]
Etiology
Etiology PMD is an X-linked disorder due to mutations or dosage alterations of the PLP1 gene (Xq22) that cause hypomyelination of the central nervous system (CNS). PMD is allelic to SPG2 which is also due to PLP1 mutations. [orpha.net]

Summary Epidemiology The estimated prevalence is 1/400,000. PMD affects males but some female heterozygotes presenting with a milder phenotype have also been reported (PMD in female carriers; see this term). [orpha.net]

Prevention
Mutations that prevent any PLP1 from being made result in a syndrome (PLP1 null syndrome) that is usually milder than classic Pelizaeus-Merzbacher disease. [emedicine.medscape.com]
[…] includes medications for seizures and spasticity; physical therapy, exercise, and orthotics for spasticity management; surgery for contractures and scoliosis; gastrostomy for severe dysphagia; proper wheelchair seating, physical therapy, and orthotics to prevent [ncbi.nlm.nih.gov]
GJC2 gene mutations that cause Pelizaeus-Merzbacher-like disease type 1 reduce the production of connexin-47, prevent the connexin-47 protein from reaching the cell membrane, or decrease the function of the protein in the gap junction. [ghr.nlm.nih.gov]
Thus, myelination helps prevent the current from leaving the axon. [wikivisually.com]
