Molecular assay reagents intended for use in identifying exchanges (i.e., translocations) between chromosome 11 band q23 and chromosome 19 band p13.1, usually involving genes MLL and ELL, respectively. This translocation is associated with acute nonlymphocytic leukemia (ANLL) in adults and, less often, in children; congenital cases are rare. Its detection may be used as a tumor marker.
