Acronyms challenge us all. There was a previous acronym listing, but this had become defunct. See this posting. I've grabbed definitions from a few locations and we can edit this post to keep it up to date.

Please submit additions, as well as corrections for definitions and links as messages below. I will add them to the list as time permits (or a moderator in my absence).

Yes, but first you have to tell us what ALD stands for.
Adrenoleukodystrophy: I also placed a link in red
X-linked adrenoleukodystrophy (X-ALD) is a genetic disease that affects the nervous system and the adrenal glands (small glands located on top of each kidney). People with this disease often have progressive loss of the fatty covering (myelin) that surrounds the nerves in the brain and spinal cord. They may also have a shortage of certain hormones that is caused by damage to the outer layer of the adrenal glands (adrenal cortex). This is called adrenocortical insufficiency, or Addison disease.[1] 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]

The reason I placed ALD is, so many ME people show similar symptoms. However, research has not yet looked into X-ALD in combination with ME/CFS. I could not find a VLCFA test mention so far.
