Editing Adrenoleukodystrophy (section)

==Asymptomology==
There are documented asymptomatic males who present no ALD symptoms well into their 60s and 70s. It's not understood how they can have an ABCD1 gene variant and possess elevated VLCFAs and not exhibit either Cerebral ALD, Adrenal Insufficiency, or Adrenomyeloneuropathy symptoms. Daughters of asymptomatic males become obligate carriers, who may themselves be asymptomatic and who can pass the variant onto their children, which then silently perpetuates ALD. Sons of asymptomatic males only receive their father's Y chromosome and therefore can't inherit ALD.<ref>{{Cite web |url=https://www.researchgate.net/publication/340791801 |title=Asymptomatic adrenoleukodystrophy in elderly males &#124; Request PDF |access-date=2021-02-05 |archive-date=2021-04-18 |archive-url=https://web.archive.org/web/20210418170257/https://www.researchgate.net/publication/340791801_Asymptomatic_adrenoleukodystrophy_in_elderly_males |url-status=live }}</ref>
