RHD*10.01 - RHD*DAU1
(ISBT table: RHD partial D v5.0)
This entry is an RHD allele.
DAU-1, RHD(S230I,T379M), RHD*689G>T,1136C>T, RHD*689T,1136T, RHD*689T,1136T (DAU1),
Molecular data
Hybrid allele encompassing at least one RHCE exon:
no
Comments on the molecular basis:
- 1 heterozygous sample in which "the new allele could not be unambiguously be proven, we assume that the known RHD*10.01 and a novel RHD*[178A>C; 689G>T] allele are present instead of two novel alleles (RHD*689C>T and RHD*[178A>C; 689G>T; 1136C>T])"
Extracellular position of one or more amino acid substitutions:

Summary: exceptional description(s), in African or African descent, or compatible with such descent (last update: Dec. 20, 2019)Detailed reports
- 3 samples samples referred for ambiguous D phenotype African
- 1/360 donors with atypical D phenotype (discrepancies or reactivity weaker than 3+) Brazilian
- 1/37782 (heterozygous with RHef00129) 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 hemizygote among 278 samples selected for the development of nonspecific quantitative next-generation sequencing. (non-random samples, may have been reported in other studies)
