Does Obama have Sickle cell Anemia? Does that explain his purple lips?
It would be impossible for him to have sickle cell anemia. The condition requires two mutant copies of the gene, and the gene is exclusive to africans. Therefore even if his father had the gene, his euro-descended mother could not have had it, so at worst he would be a sickle-cell gene heterozygote having sickle cell trait, or a carrier with no symptoms.
