Patients with NSCLC whose tumors express higher levels of AEG-1 appear to have poorer outcomes than those with lower levels of AEG-1 after treatment with TKIs, which suggests that genetic variations in AEG-1 could alter EGFR-targeted drug response in a similar fashion to NFKBIA (Table 1) [1]. The gene discussed is MTDH; the disease is non-small cell lung carcinoma.
