Gene expression analysis across multiple cancer types using The Cancer Genome Atlas dataset (34) showed elevated FAP mRNA levels in different tumor types with the highest median observed in breast (1014 RNA-Seq by Expectation Maximization [RSEM], n = 1082) and pancreatic tumors (1213 RSEM, n = 177; Supplementary Fig. S1). The gene discussed is FAP; the disease is cancer.
