I'm in the same boat - unknown autoimmune disease, talked to teams of neurologists in different health networks. All they can do is prescribe treatment for symptoms, not causes, which is frustrating.
How does one even go about sequencing their DNA?

What the heck would you do about it? We don't understand DNA and protein folding enough to actually take the output of DNA sequencing and give you something to change that. We don't have a comprehensive view of the human body or biology or DNA to do anything with it. There's not really going to be much in the way of treatment for a single instance of a random negative mutation.
If you have a genetic diagnosis you are more likely to get medical care targeting the root cause instead of treatments that can only treat the general symptoms - like anti inflammatory drug, etc. In rare cases people may get transfusions to replace their protein deficiency, etc.
