Of note, FGFR2 expression was highest in the patient’s tumor than in all other tumors from the TCGA cohort (log2 fold change = 2.01), whereas the expression levels of different tyrosine kinases, including FGFR1, 3, and 4, was in the range of the other samples (Fig. 2c and Supplementary Fig. 1c). Here, FGFR1 is linked to neoplasm.
