As we tested the associations between 439 289 SNPs and bone erosion in 385 patients with erosive RA and 326 with non-erosive RA, none of the tested SNPs reached the genome-wide significance threshold, although many loci showed modest genetic effect on bone erosion status with suggestive association (e.g., rs2741200 [P = 3.75 × 10<sup>-6</sup> ] in the SLA-TG locus and rs12422918 [P = 4.13 × 10<sup>-6</sup> ] in SRGAP1).
