Single cell analysis of clonal architecture in acute myeloid leukaemia.

ABSTRACT: We used single cell Q-PCR on a micro-fluidic platform (Fluidigm) to analyse clonal, genetic architecture and phylogeny in acute myeloid leukaemia (AML) using selected mutations. Ten cases of NPM1c mutant AML were screened for 111 mutations that are recurrent in AML and cancer. Clonal architectures were relatively simple with one to six sub-clones and were branching in some, but not all, patients. NPM1 mutations were secondary or sub-clonal to other driver mutations (DNM3TA, TET2, WT1 and IDH2) in all cases. In three of the ten cases, single cell analysis of enriched CD34⁺/CD33^- cells revealed a putative pre-leukaemic sub-clone, undetectable in the bulk CD33⁺ population that had one or more driver mutations but lacked NPM1c. Cells from all cases were transpl
