A number sign (#) is used with this entry because of evidence that leukoencephalopathy with brainstem and spinal cord involvement and lactate elevation (LBSL) can be caused by homozygous or compound heterozygous mutation in the gene encoding mitochondrial aspartyl-tRNA synthetase (DARS2; 610956) on chromosome 1q25.
