    OBJECTIVES, Familial mediterranean fever (FMF) is an autosomal recessive disease characterized by recurrent and self-limiting fever, peritonitis, arthritis, synovitis, pleuritis, carditis, and erysipelas-like lesions. The aim of this study was to investigate the frequency of the MEFV gene mutation in patients who admitted to hospital with preliminary diagnosis FMF and who had undergone a prior appendectomy. PATIENTS AND METHODS, We retrospectively reviewed the files of 52 patients between the ages of 7-18 who admitted to hospital with preliminary diagnosis of FMF and who had undergone a prior appendectomy. Age, gender and the MEFV gene mutations were included in the data. The 12 known, common MEFV gene mutations [E148Q, P369S, F479L, M680I (G/C), M680I (G/A), I692del, M694V, M694I, K695R, V726A, A744S, R761H] were investigated in the patients. RESULTS, Of these 52 cases, 29 (55.8%) were female and 23 (44.2%) were male. Their mean age was 12.1 +/- 3.1 years (range 7-18 yr). MEFV gene mutation was detected in 31/52 cases (59.6%). In this study was found an high frequency of the MEFV gene mutation in patients admitted to hospital with a preliminary diagnosis FMF who had undergone a prior appendectomy. MEFV gene mutations were M694V 16/41 (39%), E148Q 13/41 (31%), M680I 6/41 (15%), V726A 4/41 (10%) and R761H 2/41 (5%). Other genes mutations were F479L, M680I (G/A), I692del, M694I, K695R and A744S. CONCLUSION, There are too much indications of unnecessary appendectomy in MEFV gene mutation carriers. In MEFV gene mutation carriers the frequency of appendicitis can be higher than the normal population. A more detailed and extensive study should be done about it.

    The prevalence of Familial Mediterranean Fever common gene mutations in patients with simple febrile seizures
    (VERDUCI PUBLISHER, 2014) Ozen, F.; Kocak, N.; Kelekci, S.; Yildirim, I. H.; Hacimuto, G.; Ozdemir, O.
    BACKGROUND: Febrile seizures (FS) represent the most common form of childhood seizures that occurs in 2-5 % of the children younger than 6 years. There have been many recent reports on the molecular genetic and pathogenesis of FC. It has been recognized that there is significant genetic component for susceptibility of FC with different reported mutation. FEB1, FEB2, FEB4, SCNA1, SCNA2, GABRG2 and IL-1 beta are related to with febrile convulsions (FCs). Interleukin 1 beta (IL-1 beta) is a cytokine that contributes to febrile inflammatory responses. There are conflicting results on increasing this cytokine in serum during FC. AIM: The determine the association between mutations of MEFV gene product pyrine and febrile seizures. PATIENTS AND METHODS: The study was carried out on 104 children that were diagnosed as FS and 96 healthy children. MEFV gene mutations were detected and analyzed with Pyro-Mark Q24. PCR was performed using the Pyro-Mark PCR Kit and pyrosequencing reaction was conducted on instrument instructions. RESULTS: M694V is the most common mutation in our patient group and we found a significant association between MEFV gene mutations and FSs. Of 104 patients, 68 were heterozygotes for any mutation and 10 patients were compound. 17.7% of control group were heterozygotes for any studied mutation. Statistical analyses showed that there was strongly significant statistical difference between results obtained from FS and control group (X = 46.20, p < 0.0001). CONCLUSIONS: MEFV gene mutations, especially M694V mutation, are positively associated with FSs.
