Hope that information helps someone.
By the way, your factual knowledge is far greater than mine.
Only because I got a whole genome test and have been combing through studies related to my symptoms and gene variations. But that is only part of the battle. Once you figure it out then you have to find the Doctor who knows how to deal with it.
Drug processing problems? Good Luck with that. All my doctors are clueless. I did luck out and stumbled on the type of place I needed to go who actually has a clue. Specialists in Pharmacology.
My guess is that many people here have drug processing problems but just don’t know it yet.
