Brief description Chromosome translocation, in which breaks occur in two chromosomes and rejoin to form two new hybrid chromosomes, is a common genetic alteration in leukaemia. Translocations have been invaluable in identifying genes important in the development of leukaemia. The genetic consequence of translocation is either the deregulation of critical genes adjacent to the breakpoints or the formation of new hybrid genes with novel properties. We have identified the genes at the breakpoints of a T-cell leukaemia translocation involving chromosomes 4 and 11. The chromosome 11 gene, NUP98, is known to be involved in two other translocations in acute myeloid leukaemia but not in T-cell leukaemia. The chromosome 4 gene RAP1GDS has not been previously shown to be involved in human cancer. This project seeks to understand how the fusion protein NUP98-RAP1GDS (NRG) plays a role in the origin of leukaemia.
