Familial Mediterranean Fever (FMF) is an inherited disease, characterized by recurrent attacks of fever, inflammation of the abdominal lining (peritonitis), inflammation of the lining surrounding the lungs (pleurisy), painful, swollen joints (arthralgia and occasionally arthritis), and a characteristic ankle rash. This condition is also sometimes referred to as recurrent polyserositis or familial paroxysmal polyserositis.[1]

FMF is considered a rare disease worldwide. However, it is very common in people of Sephardic (non-Ashkenazi) Jewish, Armenian, Arab and Turkish heritage. Among people with these backgrounds, about 1 in 200 has FMF. The availability of genetic testing has helped identify numerous cases among several additional populations with Mediterranean roots, including: Ashkenazi Jews, Italians, Greeks, Spaniards, and Cypriots, and occasional cases in a broad range of other ethnicities (Northern Europeans and Japanese).
