FGFR2 and mucinous adenocarcinoma: Figure 1 diagrams the predicted protein structure of the FGFR2-TACC2 fusion from this patient. The patient presented with mucinous adenocarcinoma of the lung. Interestingly, there is another report of a FGFR2-TACC2 translocation identified in a mucinous stomach adenocarcinoma in The Cancer Genome Atlas (TCGA) PanCancer studies (TCGA-BR-8080-01). The findings warrant further investigation of the FGFR2-TACC2 translocation in mucinous adenocarcinoma from different origins.
