Two new RHD alleles with deletions spanning multiple exons

Background The most common large‐deletion RHD allele ( RHD*01N.01 ) includes the entire coding sequence, intervening regions and untranslated regions. The rest of large‐deletion RHD alleles reported to‐date consist of single‐exon deletions, such as RHD*01N.67 which includes exon 1. Materials and Methods Samples from two donors with RhD‐negative serology yielded unclear or inconclusive results when subject to confirmatory testing on RHD...
