Description

The first example of anti-Doa, reactive with 64% of the Caucasian population, was reported by Swanson et al. in 1965. It was not until 1972 that Molthan et al. reported the antithetical antibody anti-Dob. Thus, the Dombrock blood group system was defined and was estimated to be the fifth most useful blood group marker in Caucasians. However, limited examples of both antibodies greatly restricted broad investigations. The Dombrock system remained a simple two allele system until 1992, when Banks et al. reported that the red cells of the rare Gy(a-) Hy(a-) Jo(a-) individuals were also Do(a-b-). Consequently, these three high incidences blood factors were included within the system. Interestingly, it had already been known that all Gy(a-) red cells lacked both Hya and Joa antigens and that Hy(a-) red cells lacked Joa antigens. Ironically, Swanson reported the first examples of both anti-Doa (in 1965) and anti-Gya (1967) but as anti-Dob was, at that time, yet to be discovered any association with Doa and Gya could not be deduced.
