Integrative Analysis Reveals Differential Characteristics of DDR1 Mutant and Wild-type Gastric Cancers and Constructs their Prediction Models

The molecular typing of gastric cancer by TCGA is significant for the precision treatment of gastric cancer. However, the molecular typing of gastric cancer by TCGA lacks the typing of the rare gene DDR1. Therefore, this study aimed to integrate the analysis to reveal the differential features of DDR1 mutant and wild-type gastric cancers and construct their prediction models.
