| Protein Effect | loss of function - predicted |
| Gene Variant Descriptions | BRIP1 T997Rfs*61 indicates a shift in the reading frame starting at amino acid 997 and terminating 61 residues downstream causing a premature truncation of the 1249 amino acid Brip1 protein (UniProt.org). T997Rfs*61 has not been characterized, however, due to the effects of other truncation mutations downstream of T997 (PMID: 18628483), is predicted to lead to a loss of Brip1 protein function. |

| BRIP1 T997Rfs*61 | pancreatic adenocarcinoma | predicted - sensitive | Olaparib | Case Reports/Case Series | Actionable | In a Phase II trial, treatment with Lynparza (olaparib) resulted in a clinical benefit rate of 62.5% in advanced solid tumor patients harboring BRIP1 mutations, including a partial response in a patient with pancreatic adenocarcinoma harboring BRIP1 T997Rfs*61 (reported as c.2990_2993del) (PMID: 42105598). | 42105598 |
