Additional comments

This allele is listed as DBS-2 and not DCS-3, because the additional E233Q substitution has major impact. As expected, the serology is quite different from DCS. However, the DBS alleles are characterized by a combination of A226P and E233Q. For unknown reasons, this allele is listed by the ISBT twice, both as DBS2 (RHD*13.02) and as DCS-3 (RHD*16.02??)
