Multiple myeloma and its precursor stages, monoclonal gammopathy of undetermined significance and smouldering multiple myeloma, have a considerable degree of genetic heterogeneity. The authors of this Review discuss how single-cell studies in these individuals are enabling the mutational and phenotypic characterization of cells within the bone marrow tumour, immune microenvironment and peripheral blood to eventually guide early diagnosis, risk stratification and treatment strategies.
