Figure 4. Associations among microsatellite instability (MSI), ATM intron mutation and ATM protein loss in the gastric cancers.

(A) Frequencies of ATM protein loss by immunohistochemistry in gastric cancer subgroups by MSI status and ATM intron mutation. (B) Venn diagram showing the number of gastric cancer cases with overlapping molecular characteristics among high-level microsatellite instability (MSI-H), ATM intron mutation, and ATM protein loss.
