FGFR1 and gonorrhea: Whereas PAs and DLGNTs share a frequent KIAA1549:BRAF fusion (64% (n = 9/14) in PAs and 70% (n = 7/10) in DLGNTs), FGFR1 alterations (3 TKD mutations and 2 internal tandem duplication, ITD) were exclusively observed in PA [33% (n = 5/15)] (Fig. 1, case #30 illustrated in Fig. 2a–e).
