[PMID 22029668] A 2012 educational article explained that in autoimmune inflammatory conditions, IL-6 promotes antibody production, drives CRP levels, and has other pathological roles.
[PMID 23749187] A 2013 article titled "Identification of multiple risk variants for ankylosing spondylitis through high-density genotyping of immune-related loci" stated that the OR for the risk allele was 1.14 (1.18 in Caucasians, but only 0.99 in Asians), but the TT polymorphism was more significant. TT homozygous at rs4129267 had sIL-6R (soluble inhibiting IL-6 receptors) concentrations 73% higher than CC homozygous (28.9 versus 16.7 ng/ml; P = 7.8 × 10−17) and CRP (C-reactive protein) concentrations were 30% higher in TT than in CC (19.2 versus 14.8 mg/l).

[PMID 18439548] A 2008 study titled "Loci related to metabolic-syndrome pathways including LEPR,HNF1A, IL6R, and GCKR associate with plasma C-reactive protein: the Women's Genome Health Study" explained that "elevated levels of C-reactive protein (CRP) independently predict increased risk of development of metabolic syndrome, diabetes, myocardial infarction, and stroke" (Abstract). The IL6R SNP rs4129267 had an influence on median hsCRP levels (mg/l). They were 1.65 for Minor allele homozygous, 1.95 for heterozygous, and 1.98 for major allele homozygous.
[PMID 18439552] A 2008 article titled "Polymorphisms of the HNF1A gene encoding hepatocyte nuclear factor-1 alpha are associated with C-reactive protein" reported "results of two genetic-association studies of CRP, the Pharmacogenomics and Risk of Cardiovascular Disease (PARC) study and the Cardiovascular Health Study (CHS)." They were unable to find association between this SNP and CRP levels, but said this lack of finding may be due to their smaller sample size.
[PMID 18852330] "Interleukin-6 receptor gene, plasma C-reactive protein, and diabetes risk in women." This 2009 article explained that "SNP rs4129267 reported by the GWAS (9) was not typed in the present study. However, this SNP is in near perfect linkage disequilibrium with rs8192284 (D′ = 1 and r2 = 0.96; HapMap, CEU)." The latter SNP genotype rs8192284 AA (major allele) carried a higher risk of type 2 diabetes (OD =1 in the lowest quartile of the sample, OR=5 in the highest quartile). ORs for AC+CC (C is the minor allele) ranged from 1 to 3.

[PMID 22554704] The IL6R variation Asp(358)Ala is a potential modifier of lung function in subjects with asthma. Published 2012. Stated "The SNP rs4129267 is in linkage disequilibrium (r(2) = 1) with the IL6R coding SNP rs2228145 (Asp(358)Ala). This IL6R coding change increases IL-6 receptor (IL-6R) shedding and promotes IL-6 transsignaling." (Abstract)

This 2009 study noted a strong association with this SNP but provided no risk alleles or odds ratios.
[PMID 21496483] A 2011 study of 302 Breast cancer survivors, and follow-up data from 236 of them, "Fatigued breast cancer survivors and gene polymorphisms in the inflammatory pathway" examined "The associations between fatigue and SNPs in inflammation-related genes; IL1β (rs16944), IL6 (rs1800795), IL6receptor (rs4129267, rs4845617, rs2228145), CRP (rs2794521, rs3091244)" (Abstract). They found borderline significance associated with rs3091244, but no others. They suggested that they could not replicate the finding of CRP levels in association with (rs2228145 and rs4129267) due to their small sample size.
