Familial Mediterranean fever (FMF) is the most prevalent hereditary periodic fever, affecting 0.1% in people of Mediterranean descent. It is also reported throughout the world's populations. FMF is an autosomal recessive disorder caused by missense mutations in the MEFV gene, which encodes the pyrin protein. Mutations in pyrin may lead to uncontrolled inflammation due to IL-1beta hyperactivation. FMF is characterized by recurrent inflammatory fevers with sterile peritonitis, pleuritis, arthritis, myalgia and erysipelas-like skin lesions. Renal amyloidosis is the most severe complication, leads to renal failure. These symptoms start before 20 years of age in about 90% of cases.

H00288 Familial Mediterranean fever
Acute febrile neutrophilic dermatosis (AFND), also referred to as pyrin-associated autoinflammatory disease (PAAND), is an autosomal dominant autoinflammatory disorder characterized by fever and arthritis. Pyrin encoded by MEFV gene is a protein involved as a suppressor of inflammasome and mutations in the MEFV gene have been linked to AFND.
