Hi Ryan,
I don't suffer from neuropathy but many people on the forum do. They usually have numbness or some other outward sign. I hope they will reply.
Ataxia can be related to a genetic disorder and is being researched.
It's important to remember that ataxia is a symptom and may occur as a result of many different underlying conditions (such as MS), and may also occur due to head trauma or intoxication. Ataxia not due to any of these factors may be inherited (caused by a faulty gene which is passed down through families) or non-inherited (sporadic)

Foot drop is explained here,
Foot drop is a sign of an underlying problem rather than a condition itself. This could be muscular, caused by nerve damage in the leg, or the result of a brain or spinal injury.
Foot drop usually only affects one foot, but both feet may be affected depending on the cause. It can be temporary or permanent.

I am bumping your post up in the hope that you get some replies.
Take care,
