In this week’s episode we’ll feature new research demonstrating that certain HLA-DQ heterodimers can help predict clinical outcome following hematopoietic cell transplantation. Next, we’ll review a recent integrated and comprehensive genomic analysis that sheds new light on the molecular characteristics of large granular lymphocyte leukemia and its subtypes. Finally, we’ll review the work of a group that proposes a new and more accessible hemochromatosis classification system based on clinical characteristics and genetic features.
