GRWD1 and uveal melanoma: The expression level of GRWD1 was also positively correlated with the MSI in LIHC (P = 0.0022), uveal melanoma (UVM; P = 0.045), KIRC (P = 3.59e − 06), and SARC (P = 6.71e − 07) tissues, whereas it was negatively correlated with the MSI in READ tissue (P = 0.0022) (Figure S8).
