While no statistically significant correlations were observed between NDRG4 mRNA expression and sex (P = 0.356), age at diagnosis (P = 0.855), BMI (P = 0.782), tumor location (P = 0.824), tumor size (P = 0.783), KRAS mutation (P = 0.811), BRAF mutation (P = 0.387), PIK3CA mutation (P = 0.881) or MSI (P = 0.164). Here, KRAS is linked to neoplasm.
