摘要
African individuals harbor molecular RH variants, which permit alloantibody formation to high-prevalence Rh antigens after transfusions. Genotyping identifies such RH variants, which are often missed by serologic blood group typing. Comprehensive molecular blood group analysis using 3 genotyping platforms, nucleotide sequencing, and serologic evaluation was performed on a 7-year-old African male with sickle cell disease who developed an "e-like" antibody shortly after initiating monthly red blood cell (RBC) transfusions for silent stroke. Genotyping of the RH variant predicted a severe shortage of compatible RBCs for long-term transfusion support, which contributed to the decision for hematopoetic stem cell transplantation. RH genotyping confirmed the RH variant in the human leukocyte antigen-matched sibling donor. The patient's (C)ce(s) type 1 haplotype occurs in up to 11% of African American sickle cell disease patients; however, haplotypematched RBCs were serologically incompatible. This case documents that blood unit selection should be based on genotype rather than one matching haplotype. (Blood. 2010;116(15):2836-2838)
