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]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.6).
• BS1: Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.0246 (3754/152336) while in subpopulation NFE AF = 0.0361 (2455/68032). AF 95% confidence interval is 0.0349. There are 58 homozygotes in GnomAd4. There are 1810 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 58 AR gene
