Deletions of STK11, KEAP1, and SMARCA4 alleles (most frequently monoallelic) were observed in 14.7%, 13.5%, and 13.7%, respectively among 3194 patients (2777 for KEAP1 analysis) with non‐squamous NSCLC treated at MSKCC and DFCI [26]. This evidence concerns the gene SMARCA4 and non-small cell lung carcinoma.
