Analysis of TCGA data revealed that ACVR2A is the gene with the most dramatically different mutation rate between the MSI-H group of GCs and MSI-L/MSS group of GCs (75.34% VS 1.24%, p<0.001) (Table 1). The MSI-H GCs less
[Paragraph-level] PMCID: PMC7211323 Section: RESULTS PassageIndex: 3
Evidence Type(s): Diagnostic, Oncogenic
Justification: Diagnostic: The passage discusses the association of specific mutations (c.1310delA, 1309-1310delAA, c.285delA) with the MSI-H subtype of gastric cancers, indicating their role in defining or classifying the disease. Oncogenic: The variants mentioned are associated with a high mutation frequency and a high MSI score, suggesting their contribution to tumor development or progression in gastric cancer.
