Description

Autosomal dominant remitting MLC2B is characterized by infantile-onset of macrocephaly and mildly delayed motor development associated with white matter abnormalities on brain MRI that improve with age. As children, some patients have mild residual hypotonia or clumsiness, but otherwise have no residual motor abnormalities. About 40% of patients have mental retardation (summary by van der Knaap et al., 2010 and Lopez-Hernandez et al., 2011).Homozygous or compound heterozygous mutations in the HEPACAM gene can cause a more severe and progressive disorder associated with ataxia, spasticity, and mental retardation (MLC2A ).For a discussion of genetic heterogeneity of megalencephalic leukoencephalopathy with subcortical cysts, see MLC1 (OMIM ).
