In the GWAS meta-analysis of chronic back pain, chronic back pain was most strongly associated with rs12310519 in the SOX5 gene (Suri et al., 2018), which may indicate that SOX5 plays a role in the underlying mechanisms for other chronic back pain conditions than those causing radiculopathy since we did not discover a similar association in the present study. The gene discussed is SOX5; the disease is radiculopathy.
