### Aren't heterozygotes almost always asymptomatic, aside from being
immune to malaria?

This said, I agree that changing the levels of redundancy would not be
a simple project - since we evolved with redundancy, it's woven deep
into our control logic, and untangling this association would be a
very complex undertaking, probably much more difficult than a "simple"
sweep to remove pseudogenes, and correct mutated ones.
