* The presence of a double peak in the electropherogram indicates another RHD allele in trans. A single peak may indicate the presence of an RHD deletion in trans, the homozygous presence of an allele with the given polymorphism, or – in case of intron 1 position -28 – the presence of Ccdes in trans. † -28G > C was present in all 13 DCe haplotypes, but only in 13 of 43 Dce and 1 of 8 DcE haplotypes. ‡ Present in all RHDΨ donors. § Present in all Ccdes donors.
