SS18 and neoplasm: Given that gene expression profiles based on biological pathways could distinguish the MFS or MFS/US1 from other tumor types, we next measured the expression levels of SWI/SNF complex genes, such as SS18, SMARCA1, SAMRCA2, SMARCA4, SMARCA5, SMARCA5-AS1, SMARCAD1, SMARCAL1, SMARCB1, SMARCC1, SMARCC2, SMARCD1, SMARCD2, SMARCD3, and SMARCE1, which are often perturbed in sarcomas.
