X-linked adrenoleukodystrophy

[¦eks ‚liŋkt ə‚drē·nō‚lü·kə′dis·trə·fē]
(medicine)
An inherited peroxisomal disorder in which a defective peroxisomal membrane protein results in impaired ?-oxidation of very long chain fatty acids, which subsequently accumulate in the adrenal glands, nervous system, and testes and disrupt normal activity.

Peroxisomal disorders can be categorized as (a) single peroxisomal enzyme deficiencies, including X-linked adrenoleukodystrophy (X-ALD) and disorders attributable to defects in one of the peroxisomal (3-oxidation enzymes, such as acyl-CoA oxidase (AOX) deficiency and bifunctional protein (DBP) deficiency; and (b) disorders attributable to defects in peroxisome biogenesis.
