Genes affected

RXRG (HGNC:10479): (retinoid X receptor gamma) This gene encodes a member of the retinoid X receptor (RXR) family of nuclear receptors which are involved in mediating the antiproliferative effects of retinoic acid (RA). This receptor forms dimers with the retinoic acid, thyroid hormone, and vitamin D receptors, increasing both DNA binding and transcriptional function on their respective response elements. This gene is expressed at significantly lower levels in non-small cell lung cancer cells. Alternatively spliced transcript variants have been described. [provided by RefSeq, Jun 2010]

The c.349G>C (p.G117R) alteration is located in exon 3 (coding exon 3) of the RXRG gene. This alteration results from a G to C substitution at nucleotide position 349, causing the glycine (G) at amino acid position 117 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
