Reports
Summary: rare descriptions, in the French population (last update: Dec. 22, 2019)Detailed reports
- 1/289 289 samples with ambiguous D phenotype (333 consecutive samples with ambiguous D phenotype studied but 44 were hybrid alleles, excluded from the study) in the French (Western France) population
- 3/748 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
