=================================================================================================================================


Knevel R, Krabben A, Brouwer E, *et al*. Genetic variants in IL15 associate with progression of joint destruction in rheumatoid arthritis: a multicohort study. *Ann Rheum Dis* 2012;71:1651–7. doi: 10.1136/annrheumdis-2011-200724.

Table 2 includes a wrong minor allele frequency. The MAF of rs7665842 was incorrectly reported as 0.40. It should be 0.25.

All other presented data are correct.
