| Gene | ATRX |
| Variant | S458* |
| Impact List | nonsense |
| Protein Effect | loss of function - predicted |
| Gene Variant Descriptions | ATRX S458* results in a premature truncation of the Atrx protein at amino acid 458 of 2492 (UniProt.org). Due to the loss of most known functional domains (UniProt.org), S458* is predicted to lead to a loss of Atrx protein function. |

| ATRX inact mut | Advanced Solid Tumor | sensitive | E7449 | Preclinical | Actionable | In a preclinical study, E7449 inhibited proliferation of a ATRX-deficient cell line in culture, which demonstrated increased sensitivity compared to cells without DNA repair pathway mutations (PMID: 26513298). | 26513298 |
| ATRX inact mut | ovarian cancer | predicted - sensitive | M1774 | Case Reports/Case Series | Actionable | In a Phase I trial (DDRiver Solid Tumours 301), a patient with ovarian cancer harboring an inactivating mutation in ATRX experienced a partial response on treatment with M1774 (Ann Oncol (2022) 33 (suppl_7): S747-S748; NCT04170153). | detail... |
