- 2 samples blood donor and family study in the German population
- 1/289 289 samples with ambiguous D phenotype (333 consecutive samples with ambiguous D phenotype studied but 44 were hybrid alleles, excluded from the study) in the French (Western France) population
-
1/26243 donors with D negative phenotype in three studies with different inclusion criteria in the Swiss population (Zurich and Berne)
(study may overlap with
24679597 ) -
3/25370 D donors with D negative phenotype, screened for RHD exons 3 or 7, plus 5 and 10 in the Swiss population
(study may overlap with
24656493 ) - 1/45 among 132479 donors screened for weak D phenotype in the northeastern Chinese Liaoning Province population
- 1/129 (hemizygous) donors with weak D phenotype Thai
