I've never heard of such a thing?

Also, I've never heard of anyone having any problems breeding ball python siblings together ... there are some mutations that are just "squirrely" and have some issues ... for those, it's probably better to out cross your bloodlines whenever possible ... for other mutations like albinos, pieds, clowns, stripes .... inbreeding or line breeding for a single generation is fine.

For what it's worth, many of the double recessive combos were produced by breeding sibling double hets together.
