Involvement in diseasei

Leukoencephalopathy, megalencephalic, with subcortical cysts, 1 (MLC1)5 Publications
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA syndrome of cerebral leukoencephalopathy and megalencephaly characterized by ataxia, spasticity, seizures, delay in motor development and mild mental retardation. The brain appears swollen on magnetic resonance imaging, with diffuse white-matter abnormalities and the invariable presence of subcortical cysts in frontal and temporal lobes.
