ATRX mutation is associated with increased tumor mutation burden and PDL1 expression. a Boxplot of TMB between ATRX mutant and wild type GC patients in cohorts of TCGA, GACA-CN and GACA-JP. b Elevated expression of PDL1 was observed in patients with ATRX mutation. c-d Correlation of ATRX mutation with TMB and PDL1 expression stratified by sex (Sub1: female patients with ATRX mutation; Sub2: female patients without ATRX mutation; Sub3: male patients with ATRX mutation; Sub4: male patients without ATRX mutation)
