I thought so too!
I usually know a little about some diseases and syndromes, some of them come from diseases and disorders I or my family have, (ADHD, Anemia,) or syndromes and sicknesses I view as really interesting (Polycoria). I feel like having something like that, something people can see in real life and get affected by is a lot more real and interesting than: "the scar on my eye from the 3000000-year-old demon that gave me powers."
