Description of a cohort of UM patients used in the study.

Omics data	Platform	Description
mRNA	mRNA sequencing	A continuous matrix whose columns (the number of samples) are 80 samples and rows (the number of genes) are 20,440 genes
CNA	Affymetrix SNP6 Whole-exome sequencing	A discrete matrix whose columns (the number of samples) are 80 samples and rows (the number of genes) are 24,776 genes. There are four copy-number levels indicated for each gene, namely, −2, −1, 1, and 2. Two levels presented with minus value (i.e., −2, −1) show the loss level of copy-number compared with the two positive values (i.e., 1, 2) expressing the additional copies degree. For the 0 level, the gene is located in the diploid chromosomal region.
MET	Illumina Infinium HumanMethylation 450 platform	A continuous matrix whose columns (the number of samples) are 80 samples and rows (the number of genes) are 15,477 genes
Clinical data		Samples: 80 Overall survival (OS) status was defined as vital status (dead or alive), whereas OS time was identified as the time to UM death or last follow-up (unit: day). The follow-up time OS was truncated to 2,600 days.
