Leukoencephalopathy with Vanishing White Matter 1, also known as leukoencephalopathy with vanishing white matter, is related to leukoencephalopathy with vanishing white matter 4 and leukoencephalopathy with vanishing white matter 5. An important gene associated with Leukoencephalopathy with Vanishing White Matter 1 is EIF2B1 (Eukaryotic Translation Initiation Factor 2B Subunit Alpha), and among its related pathways/superpathways are Apoptotic Pathways in Synovial Fibroblasts and Peptide chain elongation. Affiliated tissues include brain and thalamus, and related phenotypes are brain imaging abnormality and dysmyelinating leukodystrophy
