Genes affected

RREB1 (HGNC:10449): (ras responsive element binding protein 1) The protein encoded by this gene is a zinc finger transcription factor that binds to RAS-responsive elements (RREs) of gene promoters. It has been shown that the calcitonin gene promoter contains an RRE and that the encoded protein binds there and increases expression of calcitonin, which may be involved in Ras/Raf-mediated cell differentiation. Multiple transcript variants encoding several different isoforms have been found for this gene. [provided by RefSeq, Dec 2009]

The c.271G>A (p.D91N) alteration is located in exon 6 (coding exon 3) of the RREB1 gene. This alteration results from a G to A substitution at nucleotide position 271, causing the aspartic acid (D) at amino acid position 91 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
