However, lung carcinomas, such as NSCLC, primary adenocarcinomas, and squamous cell carcinomas, are represented by a combination of an epigenetic silencing mutation of the SMARCA4 gene and SMARCA2 gene, which are primarily located at the chromosome 9p24.3, which encodes the BRM protein. This evidence concerns the gene SMARCA2 and non-small cell lung carcinoma.
