A rare interchromosomal fusion of SLC45A3 with FGFR2 in which the SLC45A3 non-coding exon 1 is fused to the intact coding region of FGFR2 has been found from a brain metastasis of a prostate cancer patient (Wu et al., 2013), indicating that there are also prostate cancer patients that likely benefit from these FGFR inhibitors. This evidence concerns the gene SLC45A3 and prostate cancer.
