I found this list at Dr. Addie’s FIP and Coronavirus website (an incredibly useful site, by the way). It’s a very handy list of the diseases that Abys are genetically more likely to get as a breed:
Familial Amyloidosis (A distant cousin of Gun-Hee and Jake’s died from this)
Feline Infectious Peritonitis (FIP) (predisposition to development of) (I can vouch for this)
Gingivitis (hyperplastic, early onset) (As I posted yesterday…!)
Progressive Retinal Atrophy (PRA) and Retinal Dystrophy (Angel’s eye wasn’t lost to this, but it’s a reason we’re watching her remaining eye so closely)
Other conditions prevalent in Abys the list doesn’t include are:
Ceruminous Otitis Externa (I’ve had earwax problems with Gun-Hee, Angel and Jake, so I agree with this one!)
Obviously, any cat can get these diseases, and not every Aby will get all these diseases. But one of the advantages to owning a purebred cat (or dog) is knowing what you may have to deal with. For example, when Jake is an elder, he’ll probably need thyroid meds, but he may not have arthritis. It’s a “better the devil you know” sort of deal, but at least there’s a good idea of what you may encounter.
