[Genetic analysis of FMF in a small village with high frequency in North West of Iran]

Familial Mediterranean Fever [FMF] is an inherited inflammatory disorder which caused by mutations in the MEFV gene. The disease is common among Turks, Armenians and Arabs, whereas no data from the neighbor countries is available. We studied an 8 years old boy with periodic fever and recurrent abdominal pain. Genotype analysis was performed by reverse-hybridization for 12 most frequent variants. Result indicated the patient and several individuals in the family were compound heterozygote or homozygote for the mutations. Genetic analysis for the other individuals without any clinical features in the village showed an allelic frequently of 22%, which is the highest rate reported to date
