We describe 2 Dutch patients with recurrent fever attacks undiagnosed
for more than 40 years. The diagnosis of periodic fever was made when molecular
analysis revealed novel mutations in the tumor necrosis factor (TNF) receptor
gene (TNFRSF1A), establishing the diagnosis of TNF
receptorassociated periodic syndrome. This syndrome is an autosomal
dominant disorder characterized by recurring episodes of fever, arthralgia,
and skin lesions that is caused by mutations in the 55-kd TNFRSF1A gene. This finding has facilitated treatment for TNF receptorassociated
periodic syndrome because blocking of TNF signaling seems to alleviate the
symptoms. Use of a short course of recombinant p75TNFR:Fc fusion protein (etanercept)
induced prolonged remission in one patient.
