IL6 and keratitis: In addition, the current study did not confirm a previous finding that people with the IL6 SNPs rs1800795 or rs1800797 were at greater risk of MK compared with SK or controls, but did find associations of other IL6 SNPs (rs1800795, rs10499563, and rs1554606) with risk of any keratitis, microbial keratitis or sterile keratitis.
