HRAS and neoplasm: We identify a trans‐ancestry prognostic subtype of bladder cancer characterized by enrichment of non‐muscle‐invasive patients and muscle‐invasive patients with good prognosis, increased CREBBP/FGFR3/HRAS/NFE2L2 mutations, decreased intra‐tumor heterogeneity and genome instability, and an activated tumor microenvironment.
