ADGRL2 and neoplasm: For SKCM, which has the most GPCR mutations among tumors types surveyed, DE analysis of primary melanomas and distant metastases that have or lack GPCR mutations (e.g., GPR98 and LPHN2) revealed little evidence that these mutations alter the tumor transcriptome, implying that such GPCR mutations are likely passenger, rather than driver, mutations (Figs 11H and S8C and S8D).
