In stratification analysis by ethnicity, we observed that FGFR4 V10I mutation may not have an impact on the risk of cancer for Asian (95%CI = 0.66–1.08, P = 0.184, Fig. 3B), African (95%CI = 0.34–1.86, P = 0.598), or individuals with European descent (95%CI = 0.83–1.42, P = 0.563). Here, FGFR4 is linked to cancer.
