Familial Mediterranean fever is known as a most frequent hereditary autoin-Xammatory among the autoinflammatory syndromes characterized by fever, arthritis and serosal inflammation. Clinically, the foremost severe symptom of the disease is amyloidosis, which may cause to renal failure. MEFV renal failure consists of ten exons and conservative mutations clustered in exon ten (M694V, V726A, M680I, M694I) and exon two (E148Q) are considered more common mutations within this coding region and that they are detected with a distinct frequency changes in line with ethnicity. The aim of this study was to research the spectrum of mutations in Azeri Turkish population. We evaluated the molecular test results of 82 patients and their parents from eighty families identified as having FMF clinical symptoms referred to Molecular Genetics Laboratory of the Department of Medical Genetics. Patients were referred by their physicians for MEFV mutation detection. The most frequent mutations were M694V respectively followed by M680I (G/C), V726A, M694I and E148Q mutations. A phenotypic variability was also ascertained between patients with different mutations and it must be considered within the daily management of FMF patients.
