Reports
Summary: rare descriptions, could be of Caucasian European descent (last update: Dec. 28, 2020)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
- 2/353 samples referred for discrepant or weak D typing in the USA 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)
