| Protein Effect | loss of function - predicted |
| Gene Variant Descriptions | APC L852* results in a premature truncation of the Apc protein at amino acid 852 of 2843 (UniProt.org). L852* has not been characterized, however, due to the effects of other truncation mutations downstream of L852 (PMID: 18199528, PMID: 10346819), is predicted to lead to a loss of Apc protein function. |

| APC L852* | colorectal cancer | predicted - resistant | G007-LK | Preclinical | Actionable | In a preclinical study, G007-LK treatment did not alter gene expression pattern or affect growth in intestinal organoids established from mouse models of colorectal cancer driven by APC L850* (corresponding to L852* in human), and had no effect on tumor cell growth and differentiation in APC L850* mouse models (PMID: 31337618). | 31337618 |
