LAG3 and acute myeloid leukemia: Preliminary screening with the chi‐squared test or Fisher's exact test showed that the genotypic frequencies of SNPs rs2227981, rs10204525, and rs2227982 in the PD1 gene (co‐dominant, recessive, and allele models) were significantly associated with susceptibility to AML (p < 0.05) and no significant association between the genotypic frequencies of SNPs in the LAG3 gene (co‐dominant, recessive, and allele models) and the susceptibility to AML (p > 0.05) was found.
