MEFV and familial Mediterranean fever: According to genetic study and analysis of 12 common MEFV gene mutations in the present study, it seems that when we encounter idiopathic uveitis in an especial area with high prevalence of FMF, it could not be considered as an underlying cause of idiopathic uveitis, although we need all mutations (nearly 250 mutations) of MEFV genes analysis to confirm this result.
