Patient with FMF and Triple MEFV Gene Mutations

Familial Mediterranean fever (FMF) is the most common auto-inflammatory disease with monogenic (MEditerranean FeVer -MEFV- gene) inherited pattern. It mainly affects ethnic groups living along the eastern Mediterranean Sea: Turks, Sephardic Jews, Armenians, and Arabs [1]. Today FMF is not rare disease in other Mediterranean ethnicities, such as Greeks, Italians, and Iranians. Here we report a child with complex allele mutations E148Q/V726A/R761H, whilst, whose mother showed E148Q/V726A and his father had R761H/wt in analysis. The severity of the disease and genotype-phenotype correlation of patient showed no significant differences with his mother and other patients with the same two mutations, V726A/R761H, E148Q/V726A, and E148Q/R761H. This type of mutation is the first report of triple mutations in FMF patients with no specific phenotype correlation.
