title: Is the HpO phenomenon in tropical populations really genetic?
abstract: Long-term studies of 98 unselected adults from a rural African community in Mali where malaria is endemic showed that the haptoglobin level of the blood increased significantly after 1 year of continuous anti-malarial treatment. This seems to indicate that hypo- or anhaptoglobinaemia in populations like this may in a considerable number of cases have a non-genetic basis.
