Recent progress in understanding the molecular mechanisms responsible for X-ALD initiation and progression hold promise for the development of novel therapies. This review summarizes developments in ...
When was X-linked ALD first discovered?
The first case of X-linked ALD (X-ALD) was likely described in 1910, [ 2] but an understanding of the biology of the disease remained untouched for decades. Seminal work in the 1970s by Powers and Schaumburg and Igarashi et al. led to the understanding that X-ALD was a lipid-storage disease characterized by VLCFA accumulation. [ 4] .
What is ABCD1?
AB CD1 encodes the adrenoleukodystrophy protein (ALDP), one of four members of the peroxisomal subfamily of ATP-binding cassette (ABC) proteins. In humans, the ABC protein superfamily has 49 members and comprises the largest family of transmembrane proteins. The characteristic feature of these proteins is the presence of one or two ...
What is an X-linked disease characterized in the most severe cases by inflammatory demyelination
Introduction. Adrenoleukodystrophy (ALD) is an X-linked disease characterized in the most severe cases by inflammatory demyelination in the brain, adrenocortical insufficiency and death. Although seven different presenting phenotypes have been reported, the two most common are the adult-onset adrenomyeloneuropathy (AMN;
What is the test for adrenoleukodystrophy?
Blood testing . These tests check for high levels of very long-chain fatty acids (VLCFAs) in your blood, which are a key indicator of adrenoleukodystrophy. Doctors use blood samples for genetic testing to identify defects or mutations that cause ALD.
What tests are done to determine if you have adrenoleukodystrophy?
Your doctor will conduct a physical examination and order several tests, including: Blood testing. These tests check for high levels of very long-chain fatty acids (VLCFAs) in your blood, which are a key indicator of adrenoleukodystrophy. Doctors use blood samples for genetic testing to identify defects or mutations that cause ALD.

What is the role of VK0214 in the cellular transport of VLCFAs?
VK0214 is a small molecule that binds to and activates the thyroid beta receptor (TBR), which controls the activity of another gene called ABCD2. This gene produces the ABCD2 protein that plays a similar role to ALDP in the transport of VLCFAs into peroxisomes.
What is the genetic disorder of ALD?
ALD is a rare, genetic metabolic disorder characterized by the accumulation of molecules called very long-chain fatty acids (VLCFAs) inside cells. A buildup of VLCFAs is toxic for cells. Mutations in the ABCD1 gene cause ALD.
How long does VK0124 last?
Mice that received VK0124 orally for 25 weeks (roughly six months) showed significantly reduced VLCFA levels in the blood, liver, and central nervous system (brain and spinal cord) compared with control mice. The treatment also increased the levels of the ABCD2 protein by 35% in the brain and 262% in the liver compared with the control animals.
What is the ABCD1 gene?
Mutations in the ABCD1 gene cause ALD. This gene contains the instructions for cells to make the adrenoleukodystrophy protein (ALDP) that is necessary to transport VLCFAs into a portion of the cell called peroxisomes. Peroxisomes then breakdown the VLCFAs so that cells can reuse the pieces to form new molecules.
What is X-linked adrenoleukodystrophy?

Where is the X-linked adrenoleukodystrophy gene located?
X-linked adrenoleukodystrophy (X-ALD) is inherited in an X-linked manner. [1] . This means that the ABCD1 gene is located on the X chromosome. The X chromosome is one of the sex chromosomes. Each woman has two X chromosomes, and each man has one X chromosome and one Y chromosome.
What is X-ALD?
There are three forms of X-ALD: a childhood cerebral form, an adrenomyeloneuropathy (AMN) type, and an adrenal-insufficiency-only-type. The disease primarily affects males. [1] X-ALD is caused by a variation ( mutation) in the ABCD1 gene and it is inherited in an X-linked. manner.
What is X-ALD caused by?
X-ALD is caused by a variation ( mutation) in the ABCD1 gene and it is inherited in an X-linked. manner. Diagnosis of the disease is based on testing the levels of a molecule called very long-chain fatty acids (VLCFA). The diagnosis can be confirmed with genetic testing.
