SWI/SNF complexes are major targets of mutations in cancer. Here, we combined multiple “-omics” methods to assess
SWI/SNF composition and aberrations in LUAD. Mutations in lung SWI/SNF subunits were highly recurrent in our
LUAD cohort (41.4%), and over 70% of the mutations were predicted to have functional impact. Furthermore, SWI/
SNF expression in LUAD suffered an overall repression that could not be explained exclusively by genetic alterations.
Finally, SWI/SNF mutations were associated with poorer overall survival in TCGA-LUAD. We propose SWI/SNF-mutant
LUAD as a separate clinical subgroup with practical implications.
