Familial Mediterranean fever: What associations to screen for?

Abstract

Familial Mediterranean fever (FMF) is the most common and best known of hereditary recurrent fever or periodic fever syndromes. It was described in 1945 and genetically characterized in 1992. It is caused by a point mutation in the MEFV gene located on the short arm of chromosome 16. It is particularly frequent among Sephardic Jews, Armenians, Turks and Middle Eastern Arabs, where the prevalence can reach 1/2000 to 1/1000. Recent publications described its frequent association with other diseases and/or syndromes, particularly those of autoimmune, genetic, and autoinflammatory origin. The objective of this review is to familiarize healthcare professionals with the main associations to look for in patients followed for FMF. The early detection of these associations makes it possible to improve the management and the prognosis of patients with FMF.
