RHD positive haplotypes in D negative Europeans.

ABSTRACT:

Background

Blood group genotyping is increasingly utilized for prenatal diagnosis and after recent transfusions, but still lacks the specificity of serology. In whites, the presence of antigen D is predicted, if two or more properly selected RHD-specific polymorphism are detected. This prediction must fail, if an antigen D negative RHD positive allele is encountered. Excluding RHDpsi and CdeS frequent only in individuals of African descent, most of these alleles are unknown and the population frequency of any such allele has not been determined.

Methods

We screened 8,442 antigen D negative blood donations by RHD PCR-SSP. RHD PCR positive samples were further characterized by RHD exon specific PCR-SSP or sequencing. The phenotype of the identified alleles was checked and thei
