Transmission of HLA-DP variants from parents to children with B-cell precursor acute lymphoblastic leukemia: log-linear analysis using the case-parent design.
To determine whether DP supertypes are associated with childhood ALL prognosis, we compared treatment outcomes in a cohort (n = 798) of DPB1-typed ALL cases in the UK Medical Research Council UKALL XI trial.
Our results suggest that DPB1*0101 may afford protection from the development of TEL-AML1+ and HeH BCP ALL, possibly as the result of a DP-restricted immune response to BCP ALL-associated antigen(s), the identification of which could have important implications for the design of prophylactic vaccines.
