MICA and graft versus host disease: Differences in MICA expression intensities in GVHD-affected tissues (Gannage et al, 2008) and on malignant cells (Sconocchia et al, 2005; Boissel et al, 2006; Nückel et al, 2010; Hilpert et al, 2012) could therefore affect the association of the SNP with specific outcome parameters after HSCT.
