  <description>Hexacosanoic acid, or cerotic acid, is a 26-carbon long-chain saturated fatty acid with the chemical formula CH3(CH2)24COOH. It is most commonly found in beeswax and carnauba wax, and is a white crystalline solid. (Wikipedia) X-linked adrenoleukodystrophy (X-ALD) is a peroxisomal disorder biochemically characterized by the accumulation of very long chain fatty acids (VLCFA), particularly hexacosanoic acid (C(26:0)) and tetracosanoic acid (C(24:0)), in tissues and biological fluids.

  <mechanism-of-toxicity>Adrenoleukodystrophy (ALD) is caused by mutations in ABCD1, a gene located on the X chromosome that codes for ALD, a peroxisomal membrane transporter protein. The exact mechanism of the pathogenesis of the various forms of ALD is not known. Biochemically, individuals with ALD show very high levels of unbranched, saturated, very long chain fatty acids, particularly cerotic acid (26:0). The level of cerotic acid in plasma does not correlate with clinical presentation. (Wikipedia)

  <health-effects>Hexacosanoic acid, or cerotic acid, is associated with adrenoleukodystrophy (also known as X-linked adrenoleukodystrophy, ALD, X-ALD, adrenomyeloneuropathy, AMN, Siemerling–Creutzfeldt disease or bronze Schilder disease) is a disorder of peroxisomal fatty acid beta oxidation which results in the accumulation of very-long chain fatty acids in tissues throughout the body. The most severely affected tissues are the myelin in the central nervous system, the adrenal cortex and the Leydig cells in the testes. (Wikipedia)</health-effects>
  <symptoms>Clinically, adrenoleukodystrophy (ALD) is a heterogenous disorder, presenting with several distinct phenotypes, and no clear pattern of genotype-phenotype correlation. As an X-linked disorder, ALD presents most commonly in males, however approximately 50% of heterozygote females show some symptoms later in life. Approximately two-thirds of ALD patients will present with the childhood cerebral form of the disease, which is the most severe form. It is characterized by normal development in early childhood, followed by rapid degeneration to a vegetative state. The other forms of ALD vary in terms of onset and clinical severity, ranging from adrenal insufficiency to progressive paraparesis in early adulthood (this form of the disease is typically known as adrenomyeloneuropathy). (Wikipedia)</symptoms>
  <treatment>Treatment options for adrenoleukodystrophy (ALD) are limited. Dietary treatment is with Lorenzo's oil. For the childhood cerebral form, stem cell transplant and gene therapy are options if the disease is detected early in the clinical course. Adrenal insufficiency in ALD patients can be successfully treated. (Wikipedia)</treatment>
