A study in 35 cases of rhabdoid tumor (RT) patients identified that there was a very low mutational rate, with variants recurring only in SMARCB1 (SWI/SNF related, matrix-associated, actin-dependent regulator of chromatin, subfamily B, member 1), which appeared to contribute to the tumorigenesis [53]. The gene discussed is SMARCB1; the disease is rhabdoid tumor.
