Genes affected

TNFRSF21 (HGNC:13469): (TNF receptor superfamily member 21) This gene encodes a member of the tumor necrosis factor receptor superfamily. The encoded protein activates nuclear factor kappa-B and mitogen-activated protein kinase 8 (also called c-Jun N-terminal kinase 1), and induces cell apoptosis. Through its death domain, the encoded receptor interacts with tumor necrosis factor receptor type 1-associated death domain (TRADD) protein, which is known to mediate signal transduction of tumor necrosis factor receptors. Knockout studies in mice suggest that this gene plays a role in T-helper cell activation, and may be involved in inflammation and immune regulation. [provided by RefSeq, Jul 2013]

Collection Method: clinical testing

The c.1723T>G (p.S575A) alteration is located in exon 5 (coding exon 5) of the TNFRSF21 gene. This alteration results from a T to G substitution at nucleotide position 1723, causing the serine (S) at amino acid position 575 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
