hidradenitis suppurativa
edit: i read wrong, that’s uncured, i could imagine that along with what you mentioned, a lot are likely nutrition-based, treatments have gotten better for a lot of things, outlooks and lifespans for certain genetic conditions, but off the top of my head i can’t think of anything that has a “cure” that’s not viral or environmental
There’s surgical interventions that cure a lot of things, like certain kinds of blindness, or pretty much anything that requires a transplant.
With two prospective diabetes cures moving towards human trials, I hope there will be a more compelling answer in 10 years or so, but that’s TBD.
