Benchmark of screening markers for KEAP1/NFE2L2 mutations and joint analysis with the K1N2-score

Abstract

Our recently published K1N2-score robustly predicts KEAP1/NFE2L2-mutations and pathway activation status, while its accessibility might be limited. We tested if the RNA expression data of six pathway-related genes and NQO1-IHC might be a reliable alternative using 348 KEAP1/NFE2L2 mutation-enriched NSCLC. While TXNRD1 RNA testing was the best-performing single-gene test, the combination of single-gene screening and validation with the K1N2-score achieved the highest performance when predicting mutation status or pathway activation.
