Some of the observed fusion partners for FGFR2 in gastric cancer include TACC2, BICC1, BTBD16, WAC, HFM1, HOOK1, INPP5F, C10orf90, WDR11, APIP, and CD44. FGFR2 gene amplification and fusion can also be concurrent, occurring most frequently in gastric cancer [46,47]. The gene discussed is APIP; the disease is gastric cancer.
