Not only do statins affect remyelination.... but they damage neurons in other ways.
There are 4 types of afferent nerve fibers that send signals to the brain ... This post illustrates the 4 types. Only C fibers are unmyelinated (and these include some of autonomic fibers from organs as well.)

This new link has a PHOTO of damage to neurons from statins:

This is the statin thread here:

There are many statin threads on PN forum and the Parkinson's forum which you can use the search function to find. Also there are some researchers who are suggesting, statins may damage mitochondria within cells, leading to the cell losing functioning ability.

Another family of drugs also damages neurons. Fluoroquinolone antibiotics:

This photo is illustrating damage by Cipro. Other fluoroquinolones are Levaquin and Avelox.
This family of drugs is often given without concern for the DNA damage they may cause in our nerve cells. Therefore they are implicated in some PN damage.

This is my fluoroquinolone post:

This damage may be lasting, and only appear after treatments are over with these drugs.

So therefore, combine a genetic reason for Wartenberg Neuropathy with use of drugs that are damaging may cause further complications, and differing presentations of this form.
The first link I provided, suggested that patients may have a combination of factors contributing and comorbid diagnoses.
