Genetic disorders are not the only problem with incest. Even the Cathecism doesn’t use “genetic disorders” as an argument to condemn incest, but instead says “Incest corrupts family relationships and marks a regression toward animality”.I’m not sure why you think it’s intrinsically evil.
Any genetic disorder that become likely with inbreeding can also appear by chance when an unrelated father and mother both have the gene associated with that disorder. That tells us that the evil of incest is not due to genetics.
If I recall correctly, incest also occurs in the case of intimate relations between siblings by marriage (step-siblings), or siblings by adoption, but may not apply to siblings separated at birth who meet later as adults.
Therefore I think incest is defined in terms of living circumstances. How do we get from that to intrinsic evil?
