| Protein Effect | unknown |
| Gene Variant Descriptions | AXL A273V lies within fibronectin type-III domain 1 of the Axl protein (UniProt.org). A273V has been associated with resistance to EGFR inhibitors (Cancer Res 2018;78(13 Suppl): nr 4903), but has not been biochemically characterized and therefore, its effect on Axl protein function is unknown (PubMed, Jan 2026). |
