Morphs with genetic problems?

I've been looking at corn snake morphs for the fun of it (for now anyway, that might change down the road ;)) and I'm curious if there's any with known issues in the same vein as spider BPs and the like. The most I've heard about is bloodreds allegedly have weaker immune systems and more than half of palmettos I've seen have bug eye so badly it looks like they're about to explode. Also this is more of a personal feeling rather than an actual technical deformity, but not fond of scaleless morphs either. Something about intentionally removing what's essentially an important aspect of an animal's anatomy (in this case preventing damage to their skin) just doesn't sit right with me.

The bug eyes in palmettos is the most prominent issue. The issues with bloodred was in the early days of the gene when it was inbred alot. Since then the gene has been outcrossed many times. One other gene is called star gazer it was closely related or in addition to sunkissed. Often times you may see ads for sunkissed that state star gazer tested. I haven't actually heard of anyone having the gazer gene.
