Heterogeneity of the O alleles at the blood group ABO locus in Amerindians.

Vox sanguinis - 1 Jan 1998

Olsson M L, Santos S E, Guerreiro J F, Zago M A, Chester M A

Abstract excerpt

BACKGROUND AND OBJECTIVES: Amerindians are blood group O, but the distribution of the various O alleles is unknown. Their ABO genotypes were compared with samples from other Brazilian ethnic groups. MATERIALS AND METHODS: Genomic DNA was examined by PCR-RFLP analysis, PCR-SSP and direct sequencing. RESULTS: An unusual allele distribution was found, with 91% of the O alleles being O1variant. Almost half of these...
