It is more common in areas with malaria because being a (single allele) carrier for the gene helps make you malaria-resistant. But it's not something which exclusively affects black people of Africa and neither do I think it is regarded as something that makes someone typically african. And it's not like all africans carry sickle cell disease.
So I don't think excluding sickle cell disease from the ship means noone with african heritage gets to go. The imaginative length you'd have to go to in order to get that out of what I wrote is, in my opinion, very far.
