A scheme of genetic rearrangement events that could lead to single ORF fusions. Grey and black arrows show any hypothetical ORFs; white circle arrow - inversion of DNA; triangles - recombination between different pieces of DNA. On the figure are shown genetic pathways that could lead to gene fusion.
