Genes affected

RARA (HGNC:9864): (retinoic acid receptor alpha) This gene represents a nuclear retinoic acid receptor. The encoded protein, retinoic acid receptor alpha, regulates transcription in a ligand-dependent manner. This gene has been implicated in regulation of development, differentiation, apoptosis, granulopoeisis, and transcription of clock genes. Translocations between this locus and several other loci have been associated with acute promyelocytic leukemia. Alternatively spliced transcript variants have been found for this locus.[provided by RefSeq, Sep 2010]

Collection Method: clinical testing

The c.545C>T (p.P182L) alteration is located in exon 5 (coding exon 4) of the RARA gene. This alteration results from a C to T substitution at nucleotide position 545, causing the proline (P) at amino acid position 182 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
