I'm not a breeder, just an owner, but wow, you do have a dilemma. My hat's off to you for wanting to do the right thing.

I think at the very least you should be ready to hold onto the litter until they are old enough to have their liver function tested (BAT's, whatever is necessary) just to certify that they don't have the problem. By that time, they will be old enough to spay/neuter, so you should go ahead and get that done before placing them, just to ensure that they remain as pets only and don't pass on the genes if case they could possibly be carriers.
