We also found six genes in MSS tumors (EYS, FAT4, FSIP2, PCDHA1, RAD50, and RECQL4) and two in MSI tumors (EXO1 and FSIP2) that were clonally mutated in multiple patients and have not been previously identified as drivers of gastric cancer or other cancers. The gene discussed is RECQL4; the disease is gastric cancer.
