Nepalese populations show no association between the distribution of malaria and protective alleles.

ABSTRACT: Malaria is perhaps the most important parasitic infection and strongest known force for selection in the recent evolutionary history of the human genome. Genetically-determined resistance to malaria has been well-documented in some populations, mainly from Africa. The disease is also endemic in South Asia, the world's second most populous region, where resistance to malaria has also been observed, for example in Nepal. The biological basis of this resistance, however, remains unclear. We have therefore investigated whether known African resistance alleles also confer resistance in Asia. We typed seven single nucleotide polymorphisms (SNPs) from the genes HBB, FY, G6PD, TNFSF5, TNF, NOS2 and FCGR2A in 928 healthy individuals from Nepal. Five loci were found to be fixed for the non-resistant
