Serotype Switching in a Partially Deleted RHD Gene

摘要

AbstractWe have studied the RH genes in donors with the RhD‐negative haplotype dCes. In contrast to the usual arrangement of genes in RhD‐negative individuals, where the lack of antigen expression is due to deletion of the entire RHD gene, we find that the dCeshaplotype includes an RHD gene with an internal deletion. Moreover, there appear to be no 5′ sequences characteristic of RHC suggesting that the RhC antigen may be encoded by a truncated RHD or a recombinant RHD/CE gene in these dCes/dce ge
