Along with the diverse molecular functions enriched for MSI events in these tumor types, some genes (TGFBR2, ACVR2A, and BAX) are particularly susceptible in MSI-H CRCs (Markowitz et al., 1995; Rampino et al., 1997; Jung et al., 2004), and BAX is also susceptible in MSI-H gastric cancers. The gene discussed is BAX; the disease is neoplasm.
