Those who are heterozygous for the sickle cell allele produce both ...

In 1954 he discovered, confirming his preconception, that people with sickle-cell trait are resistant to the deadly falciparum malaria. In the 1970s, Allison had worked out the enzyme, inosine monophosphate dehydrogenase , as a key molecule of the immune response in autoimmune diseases and in organ transplantation .
In regions where the tsetse fly carried a deadly parasite, the sickle cell trait evolved as a protective mechanism. ... The event also served as a fundraiser for the Sickle Cell Association of ...
