Genes affected

CBY1 (HGNC:1307): (chibby 1, beta catenin antagonist) Beta-catenin is a transcriptional activator and oncoprotein involved in the development of several cancers. The protein encoded by this gene interacts directly with the C-terminal region of beta-catenin, inhibiting oncogenic beta-catenin-mediated transcriptional activation by competing with transcription factors for binding to beta-catenin. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

The c.275G>A (p.R92Q) alteration is located in exon 5 (coding exon 3) of the CBY1 gene. This alteration results from a G to A substitution at nucleotide position 275, causing the arginine (R) at amino acid position 92 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
