In a landmark study, Juge et al. reported increased TERT, RTEL1, PARN, and SFPTC rare variants in patients with RA-ILD when compared with 1,010 control individuals of European ancestry, with an odds ratio (OR) of 3.17 and a 95% confidence interval (CI) of 1.53–6.12 (p < 0.001) (50). This evidence concerns the gene TERT and rheumatoid arthritis.
