Gene Description | EML4, EMAP like 4, plays a role in microtubule formation and stability (PMID: 16890222) and is required for cell proliferation and survival (PMID: 31366041). The fusion protein of EML4-ALK results in transformation activity and is present in a small percentage of patients with non-small cell lung cancer (PMID: 17625570, PMID: 23341890, PMID: 31366041, PMID: 31432686) and has also been reported in pulmonary atypical carcinoid (PMID: 31559892) and cholangiocarcinoma (PMID: 31711728). | ||||||||||

Variant | Impact | Protein Effect | Variant Description | Associated with drug Resistance |
---|---|---|---|---|
E127* | nonsense | loss of function - predicted | EML4 E127* results in a premature truncation of the Eml4 protein at amino acid 127 of 981 (UniProt.org). Due to the loss of all known functional domains (UniProt.org), E127* is predicted to lead to a loss of Eml4 protein function. | |
EML4 - ALK | fusion | gain of function | EML4-ALK results from the fusion of EML4 and ALK, resulting in constitutive kinase activity, transformation in cultured cells, and tumor formation in mouse models (PMID: 19064915, PMID: 17625570, PMID: 35138907). EML4-ALK fusions have been associated with non-small cell lung cancer (PMID: 26755435). | |
EML4 - RET | fusion | gain of function - predicted | EML4-RET results from the fusion of EML4 and RET (PMID: 33082208), which results in increased Erk phosphorylation in cultured cells (PMID: 33848463), and therefore, is predicted to lead to a gain of protein function. EML4-RET has been identified in lung cancer (PMID: 33082208, PMID: 31485557, PMID: 30487236). | |
fusion | fusion | unknown | EML4 fusion indicates a fusion of the EML4 gene, but the fusion partner is unknown. | |
inact mut | unknown | loss of function | EML4 inact mut indicates that this variant results in a loss of function of the Eml4 protein. However, the specific amino acid change has not been identified. | |
mutant | unknown | unknown | EML4 mutant indicates an unspecified mutation in the EML4 gene. | |
wild-type | none | no effect | Wild-type EML4 indicates that no mutation has been detected within the EML4 gene. |
