BTCs have a number of genomic alterations, including isocitrate dehydrogenase 1 (\n              <jats:italic>IDH1<\/jats:italic>\n              ) mutations, fibroblast growth factor receptor 2 (\n              <jats:italic>FGFR2<\/jats:italic>\n              ) rearrangements, and\n              <jats:italic>ERBB2<\/jats:italic>\n              amplifications. Therapies targeting these alterations have shown clinical benefit in patients with BTCs in the United States. However, molecular differences between races in BTCs are largely unknown. In particular, the genomic profiles of African American (AA) patients with BTCs have been infrequently reported. We sought to identify key genomic differences between AA and Caucasian patients with BTCs in the United States in the Foundation Medicine and American Association for Cancer Research (AACR) GENIE databases.\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>METHODS<\/jats:title>\n            <jats:p>BTC patients from AA and Caucasian patients from the Foundation Medicine and AACR GENIE databases were retrospectively reviewed.
