“…Given that, most of the FMF-associated vasculitis cases had MEFV gene mutations, contributing role of these mutations for vasculitis development may be considered in the pathogenesis. In line with this view, our literature search showed that most of the FMF patients reported in literature with coexistent HSV or PAN had [7,9,10,13,14,65,66] Medium vessel vasculitic diseases Polyarteritis nodosa [7, 8, 11-13, 15, 70, 71] Large vessel vasculitic diseases Unreported Unclassified vasculitic conditions Protracted febrile myalgia [16,60,[72][73][74] Behçet's disease [17,18,79] Cutaneous vasculitis [87,88] either homozygous or compound heterozygous M694V mutations. However, since many FMF patients carrying these mutations do not have associated vasculitis, we admit that this coexistence cannot solely be explained by the presence of MEFV gene mutations.…”
