Objectives. Given the pathological similarities between Behçet's disease (BD), Familial Mediterranean fever (FMF), TNF receptor-associated periodic syndrome (TRAPS) and Crohn's disease (CD) we evaluated the frequency of mutations and polymorphisms in MEFV, TNFRSFIA and CARD15 in Israeli BD patients of either Jewish or Arab descent. Methods. Fifty-four BD patients (11 Jews and 43 Arabs), evaluated with respect to the entire spectrum of BD disease manifestations, were granted a systemic severity score for BD. An association between BD manifestations and MEFV, TNFRSFIA and CARD15 variants was analysed. Results. Twelve patients (20.7%) displayed a single MEFV mutation and four patients (7.4%) had two mutated FMF alleles. Two patients (3.8%) carried a CARD15 variation and none carried a TNFRSFIA polymorphism. The frequency and distribution of mutated alleles between patients and controls was comparable (p=0.27). No statistically significant differences between carriers and non-carriers with respect to disease manifestations and severity score were calculated. Arab patients were diagnosed earlier than Jewish patients (25.8±11.6 and 37.2±10.7, respectively, p=0.06). Conclusions. The overall MEFV high carrier frequency in our cohort of BD patients seems to be attributed to their Mediterranean extraction rather than related to BD. The propensity of Arab patients (79.6%) in a cohort ofBD patients from northern Israel is highlighted in face of their proportion (20%) in the general population lending further support to arguments that favour a genetic component for BD.
