A study of 219 female melanoma patients and an equal number of controls concluded that 4 linked SNPs within the IL6R gene were associated with increased melanoma risk, but only when heterozygous. [Note that there may have been too few minor allele homozygotes to study, though.] The odds ratio associated with the minor allele of this SNP, rs6684439, was 1.74 (CI: 1.07-2.81). The 4 linked SNPs from identified in this study are: rs6684439, rs4845618, rs4845622, and rs8192284.[PMID 18781131]
