(ISBT table: not listed)
This entry is partly characterized.
Partial D - partly characterized,
Molecular data
Nucleotides:
Amino acids:
Hybrid allele encompassing at least one RHCE exon:
NA
Comments on the molecular basis:
- "HincII and TaqI restriction enzyme analysis of RHD exon 5 alone (…) It was not possible to analyze (the) sample further owing to insufficient DNA"
- "unclassifiable partial D" after analyzis by the BAGene SSP (BAG Health Care GmbH, Lich, Germany) and the BioArray molecular BeadChip assay (BioArray Solutions Ltd., Warren, USA)
Extracellular position of one or more amino acid substitutions:
Splicing:
Unconventional prediction methods:

Summary: NA, NA (last update: Aug. 25, 2020)Detailed reports
- 1/55 55 discrepant or weak D phenotypes among 33864 multiethnic patients (of African, Asian, Indoasian and European extraction) in the Canadian (Toronto) population
- 1/110 among members of the RhD-negative club Korean
- 138/748 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
- 14/60 samples with ambiguous D phenotype Indian (West India)
