Additional Information:

Description: (OMIM) Vanishing white matter leukodystrophy is an autosomal recessive neurologic disorder characterized by variable neurologic features, including progressive cerebellar ataxia, spasticity, and cognitive impairment associated with white matter lesions on brain imaging. The age at onset can range from ...
Diagnosis OMIM Van der Knaap et al. (1998) proposed the following diagnostic criteria for vanishing white matter: (1) initial motor and mental development is normal or mildly delayed; (2) neurologic deterioration has a chronic progressive and episodic course, and episodes ...
Clinical Description OMIM Van der Knaap et al. (1997) identified 9 children with a 'new' leukoencephalopathy with vanishing white matter. The 9 patients included 3 affected sib pairs; the age range was 3 to 19 years. The onset of the disease ...
Genotype-Phenotype Correlations OMIM Fogli et al. (2004) found that 68 (87%) of 78 families with MRI criteria of leukodystrophy had a mutation in 4 of the EIF2B genes. Forty-two families (62%) had a mutation in the EIF2B5 gene, and 71% had ...
Molecular genetics OMIM By a genealogic study and haplotyping, Leegwater et al. (2001) showed that single founder was involved for 12 people with VWM in 9 families. This permitted narrowing of the location of the gene to a critical region containing ...
