SET and cancer: To validate our filtration method, we selected 182 probesets (corresponding to 124 unique genes) that show testis‐specific expression (SET and SEHET classes), upregulation in at least one cancer subtype, and no expression in the corresponding somatic tissue (UCNDH; select SET plus SEHET and UCNDH filter options in columns G and L, respectively, in Supplemental File S1).
