Abstract
Background and Objectives: Genetic analysis of group B donors in Korea was performed. Materials and Methods: Exons 6 and 7 were sequenced in 12 phenotypically B3 donors 6 B3, 6 A1B 3. Results: Consensus sequences all B3 and 2/6 A 1B3 donors were present. Four A1B3 donors demonstrated a novel B allele, Bvar, in the context of A101/ or A102/Bvar genotypes. Family studies based on an A 1B3 donor with the Bvar allele and on another unrelated subject with identical genotype and phenotype revealed B var/O01 genotypes with full B-antigen expression. Conclusions: B var allele is subject to differential expression, depending on the coinherited ABO allele.
