HMGB1 and breast cancer: In HMGB1 gene, haplotype analysis did not reveal any statistical significance, and haplotype C‐T‐A (alleles in order of rs2249825, rs1412125, rs1045411 polymorphisms), which was over‐represented in patients relative to controls (11.80% versus 8.96%, P = 0.045) and was marginally associated with breast cancer risk (adjusted OR = 1.37; 95% CI: 0.97–1.93, P = 0.074).
