Biological or Clinical Significance:

Tumor necrosis factor receptor 1 (TNFR1), also known as tumor necrosis factor receptor superfamily member 1A (TNFRSF1A), is a ubiquitous membrane receptor that binds tumor necrosis factor-alpha (TNFα).

Germline mutations of the extracellular domains of this receptor were found to be associated with the human genetic disorder called tumor necrosis factor associated periodic syndrome (TRAPS) or periodic fever syndrome.[5] Impaired receptor clearance is thought to be a mechanism of the disease. Mutations in the TNFRSF1A gene is associated with elevated risk of multiple sclerosis. Serum levels of TNFRSF1A are elevated in schizophrenia and bipolar disorder, and high levels are associated with more severe psychotic symptoms. High serum levels is also associated with cognitive impairment and dementia.
