Genes affected

MCC (HGNC:6935): (MCC regulator of WNT signaling pathway) This gene is a candidate colorectal tumor suppressor gene that is thought to negatively regulate cell cycle progression. The orthologous gene in the mouse expresses a phosphoprotein associated with the plasma membrane and membrane organelles, and overexpression of the mouse protein inhibits entry into S phase. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

The c.2831G>A (p.R944Q) alteration is located in exon 18 (coding exon 18) of the MCC gene. This alteration results from a G to A substitution at nucleotide position 2831, causing the arginine (R) at amino acid position 944 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
