Reports
Summary: rare descriptions, in the French Caucasian population (last update: Dec. 22, 2019)Detailed reports
- 1/168 among 168 samples referred for weak D phenotype and/or allo anti-D in D positive individuals, 137 were characterized in the study (70 by serology, 67 by molecular analysis, 31 could not be typed because serologic typing was inconclusive and molecular typing could not be performed) in the French population (Caucasian)
- 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
- 1/430 among samples with ambigous D phenotype in the French population (Table S1)
