Imbalance in A₂ and A₂B phenotype frequency of ABO group in South India.

Blood transfusion = Trasfusione del sangue - 1 Oct 2010

Shastry Shamee, Bhat Sudha

Abstract excerpt

BACKGROUND: The heterogeneity of A and B alleles results in weak variants of these antigens. Subgroups of A differ from each other quantitatively and qualitatively. The expected frequencies of A₁ and A₂ subtypes will be in Hardy-Weinberg equilibrium for the Mendelian inheritance of the allelic A₁ and A₂ genes. The frequency of A subgroups in the population from south India is not known. The aim of our study was...
