Genes affected

AXIN2 (HGNC:904): (axin 2) The Axin-related protein, Axin2, presumably plays an important role in the regulation of the stability of beta-catenin in the Wnt signaling pathway, like its rodent homologs, mouse conductin/rat axil. In mouse, conductin organizes a multiprotein complex of APC (adenomatous polyposis of the colon), beta-catenin, glycogen synthase kinase 3-beta, and conductin, which leads to the degradation of beta-catenin. Apparently, the deregulation of beta-catenin is an important event in the genesis of a number of malignancies. The AXIN2 gene has been mapped to 17q23-q24, a region that shows frequent loss of heterozygosity in breast cancer, neuroblastoma, and other tumors. Mutations in this gene have been associated with colorectal cancer with defective mismatch repair. [provided by RefSeq, Jul 2008]

Variant summary: AXIN2 c.2013_2024del12 (p.Thr672_Arg675del) results in an in-frame deletion that is predicted to remove 4 amino acids from the encoded protein. The variant allele was found at a frequency of 0.0055 in 244704 control chromosomes, predominantly at a frequency of 0.075 within the African or African-American subpopulation in the gnomAD database, including 44 homozygotes. The observed variant frequency within African or African-American control individuals in the gnomAD database is approximately 528-fold of the estimated maximal expected allele frequency for a pathogenic variant in AXIN2 causing Colorectal Cancer phenotype (0.00014), strongly suggesting that the variant is a benign polymorphism found primarily in populations of African or African-American origin. A co-occurrence with a pathogenic variant has been reported (PMS2 c.2186_2187delTC, p.Leu729GlnfsX6; Internal testing), providing further supporting evidence for a benign role. Three ClinVar submitters (evaluation after 2014) cite the variant as benign. Based on the evidence outlined above, the variant was classified as benign. -

Significance: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
