| Gene Variant Descriptions | SMARCB1 del indicates a deletion of the SMARCB1 gene, which leads to decreased levels of SWI/SNF subunits, decreased subunit incorporation into chromatin complexes (PMID: 27941797), and hyperactivation of EGFR and MET pathway signaling in cell culture (PMID: 23576573). SMARCB1 deletion has been frequently identified in epitheloid sarcoma (PMID: 23060122). |
