Among the central nervous system (CNS) dysmyelinating disorders, Pelizaeus-Merzbacher disease (PMD) has been individualized by its X-linked mode of inheritance and the existence of corresponding animal models. Mutations in the major myelin proteolipid (PLP) gene coding for PLP and its splicing variant DM20 protein, have been demonstrated in animal mutants and more recently in PMD affected patients. We have identified, in a two-generation PMD affected family, an insertion/deletion event in the exon IV of the PLP gene, leading to the synthesis of predicted truncated PLP and DM20 proteins with altered carboxyl terminal end. This is the first report of a frameshift mutation in the PLP gene in PMD.

D002549 Diffuse Cerebral Sclerosis of Schilder A rare central nervous system demyelinating condition affecting children and young adults. Pathologic findings include a large, sharply defined, asymmetric focus of myelin destruction that may involve an entire lobe or cerebral hemisphere. The clinical course tends to be progressive and includes dementia, cortical blindness, cortical deafness, spastic hemiplegia, and pseudobulbar palsy. Concentric sclerosis of Balo is differentiated from diffuse cerebral sclerosis of Schilder by the pathologic finding of alternating bands of destruction and preservation of myelin in concentric rings. Alpers' Syndrome refers to a heterogeneous group of diseases that feature progressive cerebral deterioration and liver disease.

D004247 DNA A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).
