An adult onset demyelinating leukodystrophy characterized by autonomic abnormalities, pyramidal and cerebellar dysfunction, and symmetric demyelination of the CNS, presenting in the fourth or fifth decade of life, and that has_material_basis_in a heterozygous tandem genomic duplication on chromosome 5q23 that results in an extra copy of the lamin B1 gene (LMNB1), but also alters regulatory sequences that affect expression of other genes.

• Leukodystrophy
• Autonomic bladder dysfunction
• Autonomic erectile dysfunction
• Constipation
• Progressive neurologic deterioration
• Decreased sweating due to autonomic dysfunction
• Depression
• Nystagmus
• Symmetric peripheral demyelination

Also known as: ADLD; adult-onset autosomal dominant leukodystrophy; autosomal-dominant or late-onset type Pelizaeus-Merzbacher disease
