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...

Objectives: This study aims to investigate the effect of vascular endothelial growth factor (VEGF) gene 936C/T polymorphism (rs3025039) on appearance phenotypic characteristics familial Mediterranean fever (FMF) patients that differ with respect MEditerranean FeVer (MEFV) mutations. Here, we investigated a single functional in VEGF gene. Methods: The group consisted 223 FMF definite diagnosis a...

Background/question Familial Mediterranean Fever (FMF) is a hereditary inflammatory disorder characterised by self-resolving attacks of fever and serositis common in populations from Mediterranean ancestry [1]. Mutations affecting MEFV gene is believed to be responsible for the disease phenotype[1]. The correlation between the genotype and phenotype is not very strong, indicating the presence o...

Mutations in the MEditerranean FeVer (MEFV) gene are responsible for familial Mediterranean fever (FMF), a recessively inherited auto-inflammatory disease. Cases of dominant inheritance and phenotype-genotype heterogeneity have been reported; however, the underlying molecular mechanism is not currently understood. The FMF protein named pyrin or marenostrin (P/M) is thought to be involved in reg...

Background Familial Mediterranean fever (FMF) is an autosomal recessive autoinflammatory disorder caused by mutations in the MEFV gene. The disease is especially common among Mediterranean ancestry, mostly Armenian, Turkish, Jewish and Arab populations. We aimed to describe genotype pattern of FMF in the Jordanian children and to compare it with other populations. Materials and Methods A retros...

The aim of the current study was to determine the frequency of the Mediterranean fever (MEFV) gene pathogenic variants in 60 children diagnosed with familial Mediterranean fever (FMF) and to compare the phenotype-genotype correlation. Genomic DNA was isolated by the spin-column method from peripheral blood samples (collected in vacutainers containing EDTA) and buccal smears. The MEFV gene profi...

Introduction Familial Mediterranean Fever (FMF) is caused by mutations in the MEFV (Mediterranean FeVer) gene, which encodes pyrin. Phenotypic heterogeneity is very common in FMF patients and may partly rely on genetic heterogeneity. However, many cases having weak phenotypic-genotypic correlation, different clinical findings and therapeutic approaches with the same genotype show that FMF is no...

OBJECTIVE The aim of this study was to investigate the spectrum of Mediterranean fever (MEFV) gene mutations and genotype-phenotype correlation in children with familial Mediterranean fever (FMF) in southeast Turkey. METHODS A total of 507 children (274 females) with FMF and MEFV gene mutation(s) were included. A 15-year retrospective evaluation was conducted; parameters analyzed were: age, s...

Migraine pathogenesis involves a complex interaction between hormones, neurotransmitters, and inflammatory pathways, which also influence the migraine phenotype. The Mediterranean fever gene (MEFV) encodes the pyrin protein. The major role of pyrin appears to be in the regulation of inflammation activity and the processing of the cytokine pro-interleukin-1β, and this cytokine plays a part in mi...

BACKGROUND Identification of modifier genes and characterization of their effects represent major challenges in human genetics. SAA1 is one of the few modifiers identified in humans: this gene influences the risk of renal amyloidosis (RA) in patients with familial Mediterranean fever (FMF), a Mendelian autoinflammatory disorder associated with mutations in MEFV. Indeed, the SAA1 alpha homozygou...
