The Abantu phenotype in the ABO blood group system is due to a splice-site mutation in a hybrid between a new O1-like allelic lineage and the A2 allele.

Vox sanguinis - 1 May 2005

Hosseini-Maaf B, Smart E, Chester M A, Olsson M L

Abstract excerpt

BACKGROUND AND OBJECTIVES: Many phenotypic variations in the expression of blood group A have been explained by variations in gene structure, but unresolved samples are frequently encountered in the reference laboratory. Among ABO subgroups, A(bantu) has the highest frequency in a specified population. The molecular basis of this phenotype is now described. MATERIALS AND METHODS: Blood from Black donors...
