Summary: exceptional description(s), possible Northern European descent (last update: Dec. 22, 2019)Detailed reports
- 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
- 1 sample? reported by a German lab (AJ278873)
- 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)
