Figure 5From: Promoter polymorphisms in the chitinase 3-like 1 gene influence the serum concentration of YKL-40 in Danish patients with rheumatoid arthritis and in healthy subjectsLinkage disequlibrium between SNPs in the CHI3L1 gene in the CEU HapMap population. All SNPs are defined by RefSNP number. CHI3L1, chitinase 3-like 1 gene; SNP, single nucleotide polymorphism.Back to article page
