[https://www.uniprot.org/uniprot/TNR1A_HUMAN TNR1A_HUMAN] Defects in TNFRSF1A are the cause of familial hibernian fever (FHF) [MIM:[https://omim.org/entry/142680 142680]; also known as tumor necrosis factor receptor-associated periodic syndrome (TRAPS). FHF is a hereditary periodic fever syndrome characterized by recurrent fever, abdominal pain, localized tender skin lesions and myalgia. Reactive amyloidosis is the main complication and occurs in 25% of cases.<ref>PMID:10199409</ref> <ref>PMID:10902757</ref> <ref>PMID:11443543</ref> <ref>PMID:13130484</ref> <ref>PMID:14610673</ref>  Genetic variation in TNFRSF1A is associated with susceptibility to multiple sclerosis 5 (MS5) [MIM:[https://omim.org/entry/614810 614810]. A multifactorial, inflammatory, demyelinating disease of the central nervous system. Sclerotic lesions are characterized by perivascular infiltration of monocytes and lymphocytes and appear as indurated areas in pathologic specimens (sclerosis in plaques). The pathological mechanism is regarded as an autoimmune attack of the myelin sheat, mediated by both cellular and humoral immunity. Clinical manifestations include visual loss, extra-ocular movement disorders, paresthesias, loss of sensation, weakness, dysarthria, spasticity, ataxia and bladder dysfunction. Genetic and environmental factors influence susceptibility to the disease. Note=An intronic mutation affecting alternative splicing and skipping of exon 6 directs increased expression of isoform 4 a transcript encoding a C-terminally truncated protein which is secreted and may function as a TNF antagonist.<ref>PMID:22801493</ref>  

[https://www.uniprot.org/uniprot/TNR1A_HUMAN TNR1A_HUMAN] Receptor for TNFSF2/TNF-alpha and homotrimeric TNFSF1/lymphotoxin-alpha. The adapter molecule FADD recruits caspase-8 to the activated receptor. The resulting death-inducing signaling complex (DISC) performs caspase-8 proteolytic activation which initiates the subsequent cascade of caspases (aspartate-specific cysteine proteases) mediating apoptosis. Contributes to the induction of non-cytocidal TNF effects including anti-viral state and activation of the acid sphingomyelinase.
