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.

Unless the target analyte for X-linked adrenoleukodystrophy can be included in the current amino acid/acylcarnitine test menu, or a less expensive screening test is developed, programs may still need to invest in additional MS/MS equipment if they wish to screen for this condition.
The other entity with predominant periventricular pattern of involvement is X-linked adrenoleukodystrophy, but the condition has posterior periventricular involvement and shows enhancing active demyelinating zone on contrast.

Professor Aurora Pujol, a research professor for the Catalan Government Research Body ICREA, working as Director of the Neurometabolic Diseases Laboratory at IDIBELL, Barcelona, Spain, investigated the role of mitochondria, the power plant of the cell, in adrenoleukodystrophy, a disease caused by the inactivation of the ABCD1 transporter of fatty acids in peroxisomes.
Adrenoleukodystrophy affects the brain and causes deterioration to an insulating membrane which protects nerve cells.
Not included in this series are those cases where encephalopathy may be secondary to failure of other organs such as hepatorenal failure in tyrosinaemia type 1 and galactosaemia, adrenal failure in adrenoleukodystrophy (X-ALD) or hypoglycaemia in glycogen storage disease type 1.
An example of a few entities in this latter category include adrenoleukodystrophy, metachromatic leukodystrophy, Canavan's disease, Alexander's disease, Krabbe's disease, and sudanophilic leukodystrophy.
