MEFV and familial Mediterranean fever: Furthermore, while prior Chinese studies have attributed 19.3% of familial Mediterranean fever cases to variants in the MEFV gene—predominantly the E148Q variant (Wu et al., 2018)—in this study, five cases with potentially pathogenic MEFV variants were detected, all of which were c.2282G > A (p.Arg761His), resulting in a 1.1% carrier rate.
