| Protein Effect | loss of function - predicted |
| Gene Variant Descriptions | APC L1302Rfs*3 indicates a shift in the reading frame starting at amino acid 1302 and terminating 3 residues downstream causing a premature truncation of the 2843 amino acid Apc protein (UniProt.org). L1302Rfs*3 has not been characterized, however, due to the effects of other truncation mutations downstream of L1302 (PMID: 18199528, PMID: 10346819), is predicted to lead to a loss of Apc protein function. |
