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]

The c.1406G>A (p.R469Q) alteration is located in exon 4 (coding exon 4) of the TNFRSF21 gene. This alteration results from a G to A substitution at nucleotide position 1406, causing the arginine (R) at amino acid position 469 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
