IL13 and coronary artery disorder: We found the following results: two haplotypes in IL13 (ATG and ATA, ordered rs1881457C-rs2069744T-rs20541A) significantly contributed the risk of CAD; the promoter variant rs1881457C of IL13 not only contributed to the risk of CAD in male patients but was also involved in the development of late-onset CAD; and, in contrast, rs1881457C did not influence the severity of CAD as determined by the Gensini scores.
