These models were applied separately to RA, LORA, and young-onset RA (YORA).</p><p><strong>Results: </strong>mLOY increased significantly in LORA (odds ratio [OR] = 1.43, P = .0070). We observed a negative association between mLOY and YORA (OR = 0.66, P = .0034). On the other hand, we found consistently negative associations of autosomal mCAs or mosaic loss of X with RA, LORA, and YORA. The PRS effect sizes were lower for LORA than for YORA. mLOY with a high cell fraction strengthened the association between PRS and LORA (P = .0036), whereas the association with YORA was independent of mLOY.</p><p><strong>Conclusions: </strong>LORA was characterised by the presence of a high burden of mLOY. The observed interaction between mLOY and PRS in LORA, but not in YORA, supports different gene-environment interactions between the subsets. These data suggest that distinct pathophysiological mechanisms underlie the development of LORA and YORA.</p>","PeriodicalId":8087,"journal":{"name":"Annals of the Rheumatic Diseases","volume":" ","pages":"1313-1323"},"PeriodicalIF":20.6,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143476229","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
