Gene Variant Descriptions | ERBB4 Q707E lies within the cytoplasmic domain of the Erbb4 protein (UniProt.org). Q707E has been identified in sequencing studies (PMID: 25096233), but has not been biochemically characterized and therefore, its effect on Erbb4 protein function is unknown (PubMed, Sep 2023). |

ERBB4 mutant | lung squamous cell carcinoma | predicted - sensitive | Afatinib | Phase III | Actionable | In a Phase III trial (LUX-Lung 8), secondary analysis demonstrated favorable outcomes with Gilotrif (afatinib) treatment compared to Tarceva (erlotinib) in lung squamous cell carcinoma patients with ERBB (HER) family mutations, and ERBB4 (HER4) mutations predicted an OS (HR=0.22) and PFS (HR=0.21) benefit for Gilotrif (afatinib) over Tarceva (erlotinib) treatment (PMID: 29902295; NCT01523587). | 29902295 |
