I was looking for some tables for mutations a while back, and couldn't find any suitable ones. There are a couple over over at Seventh Order of the Random Generator, but they're way to unpredictable for what I wanted, and anyway, I needed both tables for both cosmetic mutations and more serious mutations. In the end I made a few for myself. I needed them for magical mutations that could affect PCs, but they have other potential uses of course, and obviously I built them for D&D but with a little tweaking they could be used for other games. They can be treated as a form of Curse, and require either magical healing or some kind of quest to overcome.
The first is a table for cosmetic mutations which, though they may interfere with a character's normal social interactions (because trying to buy a drink when you have decayed flesh is something NPCs might find a little gross), are not in themselves going to change a PC's stats (except possibly CHA or similar).
The second is for more substantial mutations, involving growing wings and whatnot. These will definitely change a PC's stats. It's up to the DM how this might affect play.
Minor mutations (d6)

Minor mutations (d6)
- Blue skin
- Feathers (d12: 1-red; 2-orange; 3-yellow; 4- green; 5-blue; 6-purple; 7-white; 8-black; 9-multi-coloured; 10-copper; 11-silver; 12-gold)
- Decayed flesh
- Lizard skin
- Massively hairy
- Elf ears (if victim is an Elf-type, ears shrink and become Human-like)
Major mutations (d6)
- Lobster claws for hands
- Snake body
- Human/Elf to Orc, Dwarf/Halfling to Goblin
- Become Minotaur
- Snake hands
- Wings (d6; 1-Angel; 2-Eagle; 3-Crow; 4-Dragon; 5-Butterfly; 6-Daemon)
I've created versions of these tables at the Seventh Order. The second-order tables for colours of feathers, and types of wings, are already nested into the generators.
