Genes affected

RXRA (HGNC:10477): (retinoid X receptor alpha) Retinoid X receptors (RXRs) and retinoic acid receptors (RARs) are nuclear receptors that mediate the biological effects of retinoids by their involvement in retinoic acid-mediated gene activation. These receptors function as transcription factors by binding as homodimers or heterodimers to specific sequences in the promoters of target genes. The protein encoded by this gene is a member of the steroid and thyroid hormone receptor superfamily of transcriptional regulators. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, May 2014]

Collection Method: clinical testing

The c.1362G>A (p.M454I) alteration is located in exon 10 (coding exon 10) of the RXRA gene. This alteration results from a G to A substitution at nucleotide position 1362, causing the methionine (M) at amino acid position 454 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
