چکیده

familial mediterranean fever (fmf) is a hereditary autoinflammatory disease with autosomal recessive inheritance pattern often seen around the mediterranean sea. it is characterized by recurrent episodes of fever and polyserositis and rash. recently, mefv gene analysis determines the definitive diagnosis of fmf. in this study, we analyzed 12 mefv gene mutations in more than 200 fmf patients, previously diagnosed by tel-hashomer clinical criteria, in northwest of iran, located in the proximity of the mediterranean sea. in the northwest of iran (ardabil), 216 patients with fmf diagnosis, based on tel-hashomer criteria, referred to the genetic laboratory to be tested for the following mutations; p369s, f479l, m680i(g/c), m680i(g/a), i692del, m694v, m694i, k695r, v726a, a744s, r761h, e148q. all patients were screened for mefv gene mutations by a reverse hybridization assay (fmf strip assay, vienna lab, vienna, austria) according to manufacturer’s instructions. among these fmf patients, no mutation was detected in 51 (23/62%) patients, but 165 (76/38%) patients had one or two mutations, 33 patients (15/28%) homozygous, 86 patients (39/81%) compound heterozygous and 46 patients (21/29%) were heterozygous. the most common mutations were m694v (23/61%), v726a (11/11%) and e148q (9/95%) respectively. mefv gene mutations showed similarities and dissimilarities in different ethnic groups, while it is common among arabs and armenians genotype. since common 12 mefv gene analysis could not detect up to 50% of our patients, who had fmf on the basis of clinical tel-hashomer criteria, clinical criteria is still the best way in the diagnosis of fmf in this area.

Analysis of the three most common MEFV mutations in 412 patients with familial Mediterranean fever.

BACKGROUND Familial Mediterranean fever is an autosomal recessive disease characterized by recurrent attacks of fever and serositis. The disease is caused by mutations in the MEFV gene, presumed to act as a down-regulator of inflammation within the polymorphonuclear cells. OBJECTIVES To present the results of 412 FMF patients genotyped for three MEFV mutations, M694V, V726A and E148Q. RESUL...

Background Systemic autoinflammatory diseases (SAIDs) are a group of diseases characterized by episodes of inflammation, usually manifested with fever and a variety of symptoms, including skin-rash, arthritis and abdominal pain. A clinical overlap between different SAIDs, may cause diagnosis uncertainty. Familial Mediterranean fever (FMF), the prototype of the autoinflammatory syndrome, is mani...
