IL12B and malaria: This suggests that common genetic variations within IL12B did not influence the severity of malaria in this Kenyan population, despite previous reported associations of IL12Bpro (rs17860508) with cerebral malaria in Tanzanian and Malian, but not Kenyan children [23,34], and of several other diseases with variation in IL12Bpro (rs17860508) and IL12B 3' UTR (rs3212227) [35].
