Abstract excerpt
Except for subgroup A2 and minor A, O and B alleles (Ax, O2 and B(A)), which occur at low frequencies in the population, the major ABO alleles are considered to be homogeneous entities. The present study is the first demonstration of an extensive variability linked to the more common alleles of the blood A and O genes by digestion of the genomic DNA with different restriction enzymes and hybridization with a...
