Here, it was investigated the association of INDEL variants in apoptotic genes—rs10562972 (FAS), rs4197 (FADD), rs3834129 and rs59308963 (CASP8), rs61079693 (CASP9), rs4647655 (CASP3), rs11269260 (BCL-2), and rs17880560 (TP53)—and the influence of genetic ancestry with susceptibility to malaria and parasite density in an admixed population from the Brazilian Amazon. This evidence concerns the gene CASP9 and malaria.
