It involves repeated fevers and inflammation that often affects the lining of the abdomen, chest, or joints. Causes FMF is most often caused by a mutation in a gene named MEFV. This gene creates a protein involved in controlling inflammation. The disease appears only in people who received two copies of the altered gene, one from each parent. This is called autosomal recessive.FMF most often affects people of Mediterranean ancestry. These include non-Ashkenazi (Sephardic) Jews, Armenians, and Arabs. People from other ethnic groups can also be affected. Symptoms Symptoms usually begin between ages 5 and 15. Inflammation in the lining of the abdominal cavity, chest cavity, skin, or joints occurs along with high fevers that usually peak in 12 to 24 hours. Attacks may vary in severity of symptoms. People are usually symptom-free between attacks.Symptoms may include repeated episodes of:Abdominal pain Abdominal painAbdominal pain is pain that you feel anywhere between your chest and groin. This is often referred to as the stomach region or belly.ImageRead Article Now Book Mark Article Chest pain that is sharp and gets worse when taking a breath Fever or alternating chills and fever Joint pain Skin sores (lesions) that are red and swollen and range from 5 to 20 cm in diameter Exams and Tests If genetic testing shows that you have the MEFV gene mutation and your symptoms match the typical pattern, the diagnosis is nearly certain.

Colchicine, a medicine that reduces inflammation, may help during an attack and may prevent further attacks. It can also help prevent a serious complication called systemic amyloidosis, which is common in people with FMF. AmyloidosisPrimary amyloidosis is a rare disorder in which abnormal proteins build up in tissues and organs. Clumps of the abnormal proteins are called amyloid...ImageRead Article Now Book Mark Article NSAIDs may be used to treat fever and pain. Outlook (Prognosis) There is no known cure for FMF. Most people continue to have attacks, but the number and severity of attacks is different from person to person. Possible Complications Amyloidosis may lead to kidney damage or not being able to absorb nutrients from food (malabsorption). Fertility problems in women and men and arthritis are also complications.
