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.2795G>A (p.S932N) 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 2795, causing the serine (S) at amino acid position 932 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
