Figure 1 The relationship of the CIMP-H, BRAF 1799T>A (p.V600E), and MSI-H variables in new colorectal carcinomas. Each variable is seen in approximately 15% of new CRC cases, and there is significant overlap among the variables, detailed in the subjacent table. All cases with MLH1 PHM are MSI-H, but only 75% to 80% of cases with MSI-H show MLH1 PHM.
