Genes affected

CREB3L2 (HGNC:23720): (cAMP responsive element binding protein 3 like 2) This gene encodes a member of the oasis bZIP transcription factor family. Members of this family can dimerize but form homodimers only. The encoded protein is a transcriptional activator. Translocations between this gene on chromosome 7 and the gene fused in sarcoma on chromosome 16 can be found in some tumors. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2011]

The c.722G>A (p.R241Q) alteration is located in exon 5 (coding exon 5) of the CREB3L2 gene. This alteration results from a G to A substitution at nucleotide position 722, causing the arginine (R) at amino acid position 241 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
