RREB1::MRTFB fusion gene analysis. (A) Schematic representation of the fusion event between RREB1 (orange) and MRTFB (green). The RREB1 gene is located on chromosome 6p, and the MRTFB (formerly MKL2) gene is located on chromosome 16p. Lines and filled boxes represent intronic sequences and coding exons, respectively. BP, breakpoint. (B, C) Representative screenshots from the Integrative Genomics Viewer showing split reads mapping to the 3’ region of RREB1 exon 8 and the 5’ region of MRTFB exon 11
