This study is the first to show evidence that functional variants of EGFR, namely, rs2227983 (K521R) and rs1050171 (Q787Q), are associated with an increased risk of glioma in the Korean population. Future work should confirm the functional association between EGFR variants and glioma.
Patients with Q787Q (+) received platinum-based chemotherapy in 66.7%, median progression-free survival (PFS) and overall survival (OS) were significantly shorter (7.0 vs. 9.7 months p= 0.010) and (5.6 vs. 20.5 months p< 0.001), respectively. Conclusions The synonymous EGFR Q787Q (+) variant represent a worse prognosis factor to platinum-based chemotherapy in Mexican population of NSCLC.

Our study demonstrated that EGFR Q787Q polymorphism is a germline variant in the general population. It is a protective predictor of overall survival in patients with stage IV EGFR-mutated lung adenocarcinoma treated with TKIs.
The Idylla EGFR Mutation Test has reduced sensitivity for the T790M mutation compared with NGS and ddPCR methods. The presence of an invalid T790M amplification curve may indicate a possible false negative result that warrants further testing by an orthogonal method.
