Reports
Summary: few descriptions (last update: Aug. 9, 2020)Detailed reports
- 1/748 among 748 individuals with D anomaly (weak or discrepant D phenotype or anti-D in individuals with D positive phenotype), 459 had D variants "that could be named weak D" (including alleles RHef00313, RHef00317 and RHef00318, as well as RHef00197 and RHef00283), 138 had partial D, 65 had no variant, 86 were not persued further (two variant alleles or incomplete or pending analysis) in the French population
-
3/25370 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 ) (see also "Observations" section on the RhesusBase http://www.rhesusbase.info/RHDRHD(M295T).htm) - 1/37782 270 women with variant alleles among 37782 women with D negative phenotype, tested by quantitative fetal RHD genotyping designed to detect RHD exons 5 and 7 in the Dutch population
- 2/226 226 donors considered weak D phenotype, after ruling out partial D phenotypes by using 5 monoclonal anti-D Japanese
- 1/75 RH:–1,–4 or RH:–1,–5 donors reported by a French lab
- 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 with full publications)
