Frequencies of the common mefv gene mutations in Adiyaman, Southeast Anatolia, Turkey

Abstract

Familial Mediterranean fever (FMF) is an autosomal recessive disorder characterized by fever and serosal inflammation. The reasons for the disorder are mutations in the Mediterranean fever (MEFV) gene; the most common of which are M694V, M680I, M694I and V726A. In this study, we aimed to screen these common mutations of the MEFV gene and then determine the prevalence of FMF according to these mutations in Adlyaman, Southeast Anatolia, Turkey. Seven hundred and sixty-seven healthy individuals from the region of Adlyaman participated in the study. Polymerase chain reaction-amplification refractory mutation system (PCR-ARMS) methods were used to determine the common mutations of the MEFV gene. Twenty-six (3.9%) individuals had only one mutation in the MEFV gene, 25 individuals were heterozygous and one person was homozygous for the V726A mutation (0.15%). In the present study, the V726A mutation (50.0%) was the most frequent, followed by M694V (38.5%), M680I (7.7%) and M694I (3.8%). It was seen that the carrier rate was very low and the prevalence of FMF was 0.15%, according to the common mutations of the MEFV gene in Adlyaman, Southeast Anatolia, Turkey.
