A non-sense mutation in Cd36 gene is associated with protection from severe malaria

We sought genetic evidence for the importance of host-parasite interactions involving CD36 in severe malaria. We identified a non-sense mutation in Cd36 gene and looked at the influence of this mutation on the outcome of malaria infection in 693 African children with severe malaria and a similar number of ethnically matched controls. We showed that heterozygosity for this mutation is associated with protection from severe disease (OR 0·74, 95% CI 0·55–0·99; p=0036). These findings suggest that this Cd36 mutation might have a complex effect on malaria infection by decreasing parasite sequestration, and also by decreasing host immune responses.
