AdrenoleukodystrophyA usually X-linked leukodystrophy in which impaired oxidation of saturated very long-chain fatty acids (VLCFAs) is associated with adrenal insufficiency—Addison's disease—neurologic impairment, and, in late-onset cases, adrenomyeloneuropathy, which primarily affects young men, causing spinal cord dysfunction, weakness and paraesthesias of the extremities.
Clinical findings Onset at age 5 and 10 with reversal of neurologic milestones, seizures, ataxia, Addison's disease, degeneration of visual and auditory function.
Molecular pathology Defect in ABCD1 on chromosome Xq28, which encodes a peroxisome membrane protein (ALDP or ABCD1) necessary for VLCFA beta-oxidation. VLCFA accumulation leads to damage to the CNS, peripheral nervous system and adrenal gland.
Prognosis Dismal. The treatment is generally symptomatic. Pilot data from gene therapy has been promising, but is still inconclusive as of mid-2011.
Popular culture Lorenzo Odone (1978–2008) was a famous ALD patient whose parents drove the creation of a concoction of fatty acids (Lorenzo's Oil, which begat the film of the same name) that is still being studied as a possible therapy for ALD.
