We highlighted in Supplementary Fig. S2A spsQTLs where the affected gene’s protein showed negative protein log fold-change (logFC), whereas the mRNA logFC is nonnegative, including CASP8 truncations in UCEC, ARID1A truncations in CRC and UCEC, and ATM truncations in LUAD and UCED. This evidence concerns the gene CASP8 and colorectal carcinoma.
