Abstract

FMF is an autosomal recessive disorder affecting ethnic groups which is living in the Mediterranean. The pyrin protein encoded by the MEFV gene, which leads to FMF, is thought to play a negative regulatory role in the anti-inflammatory response.MEFV gene mutations are thought to be responsible for most FMF patients. In this study, it was aimed to determine the possible mutations in the MEFV gene of 5836 patients with diagnosis of FMF and to evaluate the distribution of detected mutations among Turkish FMF cases.A 7-year patient retrospective study with diagnosis of FMF was performed. Of the DNA samples obtained from the cases, 22 mutations known to be related to disease in the MEVF gene by pyrosequencing were studied.In 5836 cases, 2774 (47,5%) mutations were detected and mutations which are related to examined regions were not detected in 3062 (52,46%). In the study group, M694V(18,59%), E148Q (12,15%), V726A (7,4%), M680I (G>C)(3,56 %), M680I (G>A)(2,59 %), R761H (1,85 %), P369S (1,9 %) and K695R (1,25 %) mutations were determined in 5836 cases. In the findings obtained in this study, types of MEFV gene mutation and frequencies in the Turkish population were clearly shown in a large series of patients. We suggest that these data could help to use more specific markers for the new FMF panels for the Turkish community.

Özet

FMF sıklıkla Akdeniz çevresinde yaşayan etnik grupları etkileyen, otozomal resesif geçişli bir hastalıktır. FMF’e yol açan MEFV geninin kodladığı Pirin proteinin antiinflamatuar yanıtta negatif bir düzenleyici olarak rol oynadığı düşünülmektedir. FMF hastalarının çoğundan MEFV gen mutasyonlarının sorumlu olduğu düşünülmektedir. Bu çalışmada, FMF tanısı almış 5836 olgunun MEFV genindeki olası mutasyonlarının tespit edilmesi ve tespit edilen mutasyonların Türk FMF olguları arasındaki dağılımının değerlendirilmesi amaçlanmıştır.FMF tanısı almış, 7 yıllık hasta profili ile retrospektif bir çalışma yapılmıştır. Olgulardan elde edilen DNA örneklerinden, pirosekanslama ile MEFV geninde hastalıkla ilişkisi olduğu bilinen 22 mutasyon bölgesi çalışılmıştır. Toplam 5836 olgunun 2774’ünde (% 47,5) mutasyon saptanırken, 3062’sinde (% 52,46) incelenen bölgelere ilişkin mutasyon gözlenmemiştir. .Çalışma grubundaki 5836 olgunun % 18,59’de M694V, % 12,15’de E148Q, % 7,4’de V726A, % 3,56’de M680I (G>C), % 2,59’de M680I (G>A), %1,85’de R761H, % 1,9’de P369S ve %1,25’de K695R mutasyonları tespit edilmiştir. Bu çalışmada elde edilen bulgular doğrultusunda, Türk toplumundaki MEFV gen mutasyon tipleri ve frekansları geniş bir hasta serisiyle net bir şekilde ortaya konulmuştur. Bu verilerin Türk toplumunda yeni FMF panelleri için daha spesifik belirteçlerin kullanılmasına yardımcı olabileceğini düşünmekteyiz.
