Pelizaeus-Merzbacher disease (PMD) is an X-linked dysmyelinating disorder characterized by nystagmus, hypotonia, ataxia, progressive spasticity, and cognitive decline. Článek Pathologic and Phenotypic Alterations in a Mouse Expressing a Connexin47 Missense Mutation That Causes Pelizaeus-Merzbacher–Like Disease in Humans Glucose-6-phosphate dehydrogenase deficiency (G6PDD) is an inborn error of metabolism that predisposes to red blood cell breakdown. Most of the time, those who are affected have no symptoms. The following 17 pages are in this category, out of 17 total. This list may not reflect recent changes (learn more). This is a list of major and frequently observed neurological disorders (e.g., Alzheimer's disease), symptoms (e.g., back pain), signs (e.g., aphasia) and syndromes (e.g., Aicardi syndrome). An eponymous disease is a disease, disorder, condition, or syndrome named after a person: usually the physician or other health care professional who first identified the disease; less commonly, a patient who suffered from the disease… Normal looking at birth and for the first few years, hypotonic (floppy), in particular difficulty to hold the head, possibly difficulty to thrive, possibly with delayed myelination (if so, some cases are reported with an MRI pattern similar…

Pelizaeus–Merzbacher disease is an X-linked neurological disorder that damages oligodendrocytes in the central nervous system. It is caused by mutations in proteolipid protein 1, a major myelin protein. It is characterized by hypomyelination and belongs to a group of genetic diseases referred to as leukodystrophies. Pelizaeus-Merzbacher disease is a disorder that affects the brain and spinal cord. It is a type of leukodystrophy and is characterized by problems with coordination, motor skills, and learning. The age of onset and the severity of the symptoms varies greatly depending on the type of disease.
BACKGROUND. Pelizaeus‐Merzbacher disease (PMD) is a recessive, X‐linked leukoencephalopathy attributed to impaired myelination during central nervous system development, caused by defects in the proteolipid protein 1 (PLP1) gene.PMD presents clinical variability, ranging from the severe connatal form to the classic form.

Publications Authored by Jingmin Wang Theoretically, a mutation in any of the genes on chromosome X may cause disease, but below are some notable ones, with short description of symptoms: In the later stages of the disease in which both ventricles are involved shortness of breath may develop, especially when lying flat. Patients typically present in early childhood with recurrent infections, in particular with extracellular, encapsulated bacteria. XLA is deemed to have a relatively low incidence of disease, with an occurrence rate of approximately 1 in 200… Many genes associated with syndromic cases of cleft lip/palate (see above) have been identified to contribute to the incidence of isolated cases of cleft lip/palate. It is also related to other neurodegenerative diseases caused by similar mutations, such as Huntington's disease.
Mutations in TUBB4A are associated with Pelizaeus–Merzbacher disease.
Pelizaeus–Merzbacher disease is an X-linked neurological disorder that damages oligodendrocytes in the central nervous system. Ludwig Merzbacher (9 February 1875 – 30 October 1942) was a German neuropathologist and psychiatrist born in Florence, Italy. Pelizaeus died in Kassel on August 11, 1942.
