چکیده
Pelizaeus-Merzbacher disease (PMD) is a rare and progressive condition affecting the central nervous system. [1] It is one of a group of gene-linked disorders known as the leukodystrophies, which are all characterised by myelin sheath abnormalities. This is due to a mutation in the gene that controls the production of a myelin protein called proteolipid protein 1 (PLP1). The exact type of PLP1 mutation dictates the onset and severity of PMD. PMD can be classified into different types:

Proton MR spectroscopy in Pelizaeus-Merzbacher disease.
Proton MR spectroscopic findings in two patients with genetically defined Pelizaeus-Merzbacher disease revealed ratios of N-acetylaspartate/creatine and choline-containing compounds/creatine that were not significantly different from those found in a population of healthy subjects. These findings suggest that proton MR spectroscopy can aid in the diagnosis of Pelizaeus-Merzbacher disease.

BACKGROUND Classic Pelizaeus-Merzbacher disease is a rare x-linked disorder of proteolipid protein expression first described clinically in 1885. This disease is characterized by abnormal eye movements, very slow motor development and involuntary movements. The causative gene is PLP1. CASE PRESENTATION A 1-year-old boy was referred to our clinic due to abnormal eye movements. He had horizonta...
متن کاملMagnetic resonance imaging pattern recognition in hypomyelinating disorders.
Hypomyelination is observed in the context of a growing number of genetic disorders that share clinical characteristics. The aim of this study was to determine the possible role of magnetic resonance imaging pattern recognition in distinguishing different hypomyelinating disorders, which would facilitate the diagnostic process. Only patients with hypomyelination of known cause were included in ...
متن کاملAdult-onset neurodegenerative disorder due to proteolipid protein gene mutation in the mother of a man with Pelizaeus-Merzbacher disease.
A 23-year-old man with Pelizaeus-Merzbacher disease had a novel mutation, C344A (Thr115Lys), in exon 3 of the proteolipid protein gene (PLP) His mother, heterozygous for the mutation, developed progressive personality change and a gait disorder in her mid-20s. Her MRI at age 53 showed a diffuse severe leukodystrophy. This report extends the phenotypic range of disease due to PLP gene mutations ...
