| Gene Variant Descriptions | APC T1556Nfs*3 indicates a shift in the reading frame starting at amino acid 1556 and terminating 3 residues downstream causing a premature truncation of the 2843 amino acid Apc protein (UniProt.org). T1556Nfs*3 retains binding with Axin1 but confers a loss of function to Apc as demonstrated by decreased beta-catenin recruitment, phosphorylation, and ubiquitination in cultured cells (PMID: 34352208). |
