Reports
Summary: few descriptions, in Japanese, Indians and Europeans of unknown descent (last update: June 11, 2020)Detailed reports
- 1/161 random donors with weak D phenotype; DVI samples were excluded by serologic testing in the German population (Southwestern Germany), White (Table 6)
- 0/270 donors with weak D phenotype White, in the German (Northern Germany) population
- 0/146 donors with weak D phenotype White, in the Austrian (Tyrol) population
- 1/168 among 168 samples referred for weak D phenotype and/or allo anti-D in D positive individuals, 137 were characterized in the study (70 by serology, 67 by molecular analysis, 31 could not be typed because serologic typing was inconclusive and molecular typing could not be performed) in the French population (Caucasian)
- 2/289 289 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
-
1/45 among 763408 donors, after ruling out partial D phenotypes by using 5 monoclonal anti-D, 75 were considered weak D phenotype and 45 were genotyped Japanese
(1 sample in common with
27183894 ) -
2/226 226 donors considered weak D phenotype, after ruling out partial D phenotypes by using 5 monoclonal anti-D Japanese
(1 sample in common with
26340140 ) - 2/223 donors with D negative phenotype initially, found to have D antigen expression (67 of the 223 samples of the cohort) or samples referred with discrepant or weak D typing, or discrepancies with previous typings, or anti-D in D positive individuals (156 of the 223 samples of the cohort) in the Indian population
- 1 hemizygote among 278 samples selected for the development of nonspecific quantitative next-generation sequencing. (non-random samples, may have been reported in other studies)
