Abstract excerpt

BACKGROUND AND OBJECTIVES: In several populations, including the Japanese, the frequency of the A2B phenotype is significantly higher than expected based on the A2 phenotype frequency. To understand the genetic basis of this 'excess' of A2B, we examined ABO alleles in individuals with A2-related phenotypes. MATERIALS AND METHODS: ABO alleles were identified by means of polymerase chain reaction single-strand...
