TRAPS (tumor necrosis factor receptor associated periodic syndrome) is a genetic disease with an autosomal dominant (one gene defect is enough to result in having the disease) inheritance. That means that either one of the parents is ill with a variant of the disease or that the gene defect was newly formed in the child with the disease (de novo mutation). Besides episodes of fever, other symptoms include abdominal pain, diarrhea, migratory (moves from one place to another) painful red skin rashes, muscle pain and swelling around the eye. The gene defect was only recently discovered. The former name of this syndrome was familial hibernian fever.
