Aberrant expression of the LHX4 LIM-homeobox gene caused by t(1;14)(q25;q32) in chronic myelogenous leukemia in biphenotypic blast crisis..     ///    "By use of long-distance inverse polymerase chain reaction (PCR), we cloned the chromosomal breakpoint and revealed that the immunoglobulin heavy chain gene is fused near its Emu enhancer region to the 5' region of the LHX4 LIM-homeobox gene, whose expression is restricted to the central nervous system.
