However, ESR, CRP, and autoantibodies, including anti-threonyl-transfer ribonucleic acid synthetase anti-body (anti-PL-7), anti-glycyl-transfer ribonucleic acid synthetase antibodies (anti-EJ), anti-histidyl-transfer ribonucleic acid synthetase antibody (anti-JO-1), anti-melanoma differentiation-associated gene 5 antibodies (anti-MDA-5), and antibodies of Ro-52 (anti-Ro-52), showed no significant difference in association with PM/DM-ILD. This evidence concerns the gene TRIM21 and dermatomyositis.
