Vanishing white matter is a leukoencephalopathy that usually affects young children. Five genes were found recently for this disease, allowing a DNA-based diagnosis. The authors describe six patients homozygous for the Arg113His mutation in eIF2Bε. Only one had a childhood onset; four had a later onset and a protracted disease course; one adult still has no symptoms. Our data suggest that the Arg113His mutation is particularly mild and should be considered in the differential diagnosis of adult diffuse leukoencephalopathies, independent of whether there are associated clinical signs, an episodic course, or MRI shows white matter rarefaction/cystic degeneration.
