Here, a significant enrichment of sQTL SNPs was found among the loci associated with rheumatoid arthritis when excluding MHC (p = 0.032, Odds ratio (OR) around 2 when comparing sQTL with non-sQTL, one-tailed Fisher’s exact test with Bonferroni correction) and on the border of significance when including MHC (p = 0.064, OR around 1.8). Here, HLA-C is linked to rheumatoid arthritis.
