In OvCa_84 tumor sample, the predicted RE neoantigen ILVRSLLVL from Oxysterol Binding Protein Like 9 (OSBPL9) (chr1:51752522) was experimentally discovered in complexed with MHC I via mass spectrometry with high confidence (q value <0.05) (Figure 3B, Table S8). This evidence concerns the gene OSBPL9 and neoplasm.
