Our study investigated in silico the associations between FGFR2 expression in breast cancer subtypes using publicly available TCGA data, and further interrogated the FGFR2 exon 8 and exon 9 expression levels, as proxies of the FGFR2 IIIb and IIIc isoforms, in clinical subtypes. Here, FGFR2 is linked to breast cancer.
