MEFV gene encodes a component of pyrin inflammasome, whose variants cause familial Mediterranean fever (FMF). We experienced a recurrent MAS case with homozygous MEFV P369S variants accompanied by Sj\u00f6gren syndrome and pulmonary arterial hypertension, whose recurrent MAS was successfully treated with canakinumab. Pathogenicity of MEFV P369S variant is still inconsistent, and clinical interpretation of this variant is challenging. Thus, we reviewed previous literatures and revealed that the majority of FMF patients with collagen diseases in carried MEFV P369S variant, all of which were reported from Japan. In this case-based review, we clarify the epidemiology of MEFV variants in collagen diseases and discuss the significance of their genetic analysis.<\/jats:p>","DOI":"10.1093\/mrcr\/rxaf016","type":"journal-article","created":{"date-parts":[[2025,3,5]],"date-time":"2025-03-05T07:20:27Z","timestamp":1741159227000},"source":"Crossref","is-referenced-by-count":0,"title":["Successful
