IFNG and breast cancer: It has been described that the SNP rs2069705 (IFNG) differs significantly between Chinese and white individuals, as was highlighted in a study that evaluated the association of IFN-γ-related polymorphisms with breast cancer in healthy cases and controls, with frequencies of 50.9% and 52.9% for the homozygous GG genotype and 8.4% and 6.3% for the homozygous TT genotype, respectively, within a Chinese population, which aligns with the present study [17].
