The exact pathogenesis of familial mediterranean fever is not fully understood. However, nearly all the cases are due to a mutation in the MEFV gene, which codes for a protein called pyrin. Normally, pyrin regulates the production of interleukin-1β (IL-1β), an important pro-inflammatory cytokine. When mutation occurs, mutated protein is unable to suppress expression of IL-1β, therefore an inflammatory response would develop results in clinical manifestation of FMF. The disease inherits in an autosomal recessive mode. However, there is an increasing number of data reporting the autosomal dominant inheritance.
