- - - - How would you explain some of the differences that we see between various groups and the prevalence of certain genetic diseases, such as sickle cell anemia in the African-American community?
      - That’s a great example. Sickle cell is not an African-American or African disease, although it occurs in higher frequency in these populations. But this is not a racial difference; it is a matter of ancestry, geography and evolution. Sickle-cell occurs in higher frequency in populations from regions of the world where malaria is or once was common, as sickle cell is a disease that is an evolutionary adaptation to exposure to malaria.
      - The sickle-cell trait is believed to be protective against malaria. Thus, sickle-cell disease is at its highest frequency in West Africans and people of West African descent. But this trait is not common in other regions of Africa, where malaria is not as prevalent. Therefore, it is not an “African” disease. Sickle cell also appears in other regions of the globe, in other human populations, including populations in the Mediterranean Basin, the Arabian Peninsula, and on the Indian subcontinent, where these populations also saw this adaptation to resist malaria.
