Pelizaeus–Merzbacher disease is the common name for hypomyelinating leukodystrophies (HLD). [6] There are at least 26 HLD variants cataloged by the National Institutes of Health National Library of Medicine [ 7 ] and the Online Mendelian Inheritance in Man (OMIM) compendium of human genes and genetic phenotypes.
This condition was first discovered in 1964 by E Zerbin-Rüdin et al. when they described (what they thought to be) a familial autosomal dominant variant of Pelizaeus-Merzbacher disease with onset in adulthood. [32]
While the disease is fatal, the age of onset is a key factor, as infants have a typical life expectancy of 2–8 years, while adults typically live more than a decade after onset. Treatment options are limited, although hematopoietic stem cell transplantations using bone marrow or cord blood seem to help in certain leukodystrophy types, while ...
Proteolipid protein 1 (PLP1) is a form of myelin proteolipid protein (PLP). Mutations in PLP1 are associated with Pelizaeus–Merzbacher disease.It is a 4 transmembrane domain protein which is proposed to bind other copies of itself on the extracellular side of the membrane.
A new report on mortality in the United States shows a decrease in life expectancy for the first time in more than two decades US life expectancy declines, as Alzheimer's disease deaths increase ...
In a myelinoid model of Pelizaeus-Merzbacher disease (PMD) developed in 2018, treatment with a modulator of ER stress pathways called GSK2656157, an inhibitor of protein-kinase-R-like ER kinase, partially rescued PLP1 perinuclear retention mobilizing it away from the ER and into the processes of oligodendrocytes.

With an estimated 6.9 million Americans aged 65 and older currently living with Alzheimer's disease, the road to a cure seems long and uncertain.. But as the year comes to a close, experts are ...
L1 syndrome is a group of mild to severe X-linked recessive disorders that share a common genetic basis. The spectrum of L1 syndrome disorders includes X-linked complicated corpus callosum dysgenesis, spastic paraplegia 1, MASA syndrome, and X-linked hydrocephalus with stenosis of the aqueduct of Sylvius (HSAS).
