BackgroundAlthough more than 80 weak D types have been reported, many rare alleles probably remain unidentified. However, direct evidence that associates intronic mutations in the RHD gene with weak D types is lacking.
Study Design and MethodsBlood samples were obtained from Shanghai Blood Center. D– samples typed in routine laboratories were tested using a monoclonal immunoglobulin M reagent, an...
BACKGROUND: The D variant phenotypes are often categorized into weak D types and partial D types. Although the molecular basis underlying the partial D phenotype has been investigated in several races, data from Chinese populations are rare.
STUDY DESIGN AND METHODS: We collected partial D samples from 1,274,540 blood donors, as well as from sporadic patients in the Chinese population, over a 4‐year...
