A positive association was found between HLA-DQA1*0104 and DM (p = 0.01; corrected p (pcorr) NS; odds ratio (OR) = 2.58; 95% confidence interval (CI): 1.18–5.64), while an inverse correlation was noted between HLA-DQB1*0303 and myositis patients with interstitial lung inflammation (p = 0.01; pcorr NS; OR = 0.25; 95% CI: 0.07–0.73). Here, HLA-DQB1 is linked to dermatomyositis.
