Reports
Summary: few descriptions, in several Central European populations, or compatible with such descent (last update: April 29, 2020)Detailed reports
- 2/96 among almost 3 million blood donations, 621685 had D negative phenotype; 46133 donors were first time donors with D negative phenotype and, when tested, 96 had RHD intron 4 in the German population
- 1/31200 consecutive donors with D negative phenotype, tested for presence of RHD intron 4, exon 7 and/or exon 10 in the Polish 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 ) -
1/25370 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 ) - 6/2027 2027 donors with D positive phenotype, C and/or E positive, screened for RHD exons 4, 5 and 10 and for DEL phenotype in the Australian population
- 2 to 10 /136000 among about 136.000 donors with D negative phenotype, systematically tested for the presence of the RHD gene; the RHD gene was detected in 300 donors in the German population (some samples may overlap with other studies)
-
1/46,756 first time donors with D negative phenotype, tested for RHD exon 7 and adsorption-elution with a polyclonal anti-D in the German population (Northern)
(overlaps with
999999913 ; some samples may overlap with full publications) (overlaps with999999988 ; some samples may overlap with19243542 ) - 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)
