Megalencephalic Leukoencephalopathy With Subcortical Cysts 2a; Mlc2a

Description

Megalencephalic leukoencephalopathy with subcortical cysts-2A is an autosomal recessive neurodegenerative disorder characterized by infantile-onset macrocephaly and later onset of motor deterioration, with ataxia and spasticity, seizures, and cognitive decline of variable severity. Brain MRI shows typical white matter abnormalities, including swelling of the cerebral white matter and subcortical cysts, in all stages of the disease (summary by Lopez-Hernandez et al., 2011).Heterozygous mutations in the HEPACAM gene can cause a similar, but less severe disorder that shows improvement of MRI changes with age (MLC2B ).
