As for IL-10 rs1800896, race effect was also observed, however, with increased risk of osteosarcoma observed in Asians under the homozygous, recessive, and allele model but not in Caucasians, but, with only one study reported in each race and a non-significant p-value for subgroup analysis, the race effect cannot be concluded. This evidence concerns the gene IL10 and osteosarcoma.
