Tumor necrosis factor Receptor Associated Periodic Syndrome, or TRAPS, is a very rare autoinflammatory disease that usually starts in children before the age of 4 years.1–5
TRAPS flares include the following symptoms:4,5,7
TRAPS flares can last a few days to a few months, but typically last about 3 weeks.7
They usually occur spontaneously, but can also be triggered by:7
Possible symptoms of TRAPS (modified according to 2,4,5,7,8)
With TRAPS, the innate immune system is activated due to changes in a gene coding for a protein called the tumor necrosis factor receptor, which is involved in the inflammatory response.2,7,11
The genetic change which leads to TRAPS developing in a child can be inherited from either parent. 2,7 There are cases of patients with non-inherited mutations for TRAPS, who can in turn pass the mutation on to their children.7
TRAPS is a very rare autoinflammatory disease that typically manifests in children before they reach the age of 4.1–5
Over the course of TRAPS, the fever bouts usually become less intense. Some patients can experience long periods of time between flares or have less frequent or severe flares in adulthood, but TRAPS is a lifelong condition.
In approximately 3 out of every 20 people, TRAPS can lead to amyloidosis.4 This is a condition in which a protein called amyloid builds up in the kidneys, eventually leading to kidney failure.9 But the good news is that recent advances in diagnostic techniques – which have helped to pinpoint a person’s precise type of amyloidosis, together with new medications, have meant that amyloidosis is now much more treatable than it used to be.10
