The most common of these rearrangements involves a pericentric inversion on the short arm of chromosome 2, inv(2)(p21p23), which creates a fusion gene encoding the amino-terminal portion of EML4 (2p21) and the intracellular region of ALK (2p23), genes that are normally approximately 13 Mb apart.
Portela-Castro and Julio-Junior (2002) suggests that these changes may have been the result of pericentric inversions and that perhaps these cytotypes correspond to different species of Bryconamericus.
