* The sum is less than 116 alleles, because homozygous occurrences were not accounted for. † All RHDΨ alleles detected carried the 37 bp duplication at the intron3/exon 4 junction and the five single nucleotide substitutions 609G > A, 654G > C,667T > G,674C > T, and 807T > G as previously described by Singleton et al. [5]. ‡ In three donors, the observed aberrations would also be compatible with the presence of the DIII type 4 allele, because normal RHD sequences occurred in trans.
