| Protein Effect | loss of function - predicted |
| Gene Variant Descriptions | APC S1421Rfs*52 indicates a shift in the reading frame starting at amino acid 1421 and terminating 52 residues downstream causing a premature truncation of the 2843 amino acid Apc protein (UniProt.org). S1421Rfs*52 has not been characterized, however, due to the effects of other truncation mutations downstream of S1421 (PMID: 18199528, PMID: 10346819), is predicted to lead to a loss of Apc protein function. |
