Extensive polymorphism of ABO blood group gene: three major lineages of the alleles for the common ABO phenotypes

Abstract: Polymorphism of the ABO blood group gene was investigated in 262 healthy Japanese donors by a polymerase chain reactions-single-strand conformation polymorphism (PCR-SSCP) method, and 13 different alleles were identified. The number of alleles identified in each group was 4 for A1 (provisionally called ABO*A101, *A102, *A103 and *A104 according to the guidelines for human gene nomenclature), 3 for B (ABO*B101, *B102 and *B103), and 6 for O (ABO*O101, *O102, *O103, *O201, *O202 and *O203).

“…Genotypes and their allelic frequencies in Japanese population were previously reported 15 and shown in Figure 1. Four groups of alleles, A (A101, A102, A103), B (B101, B102, B103, A104), O1 (O101, O102, O202, O203) and O2 (O103, O201) were identified by the analysis of two genetic polymorphisms (nucleotides 261, 297) in exon 6 of the ABO gene.…”

“…DNA variants and their allelic frequencies reported in the Japanese are indicated. 15 The blood group O gene has a single base deletion at position 261 resulting in a frame-shift mutation and causing protein termination at codon 117.…”

“…Up to now, five novel Ael alleles have been identified and characterized (Olsson et al 1995;Ogasawara et al 1996aOgasawara et al , 1996bSeltsam et al 2003;Sun et al 2003;Wu et al 2005). The Ael allele described herein was also transmitted in a straightforward manner through two generations.…”

“…[20][21][22][23][24][25][26] Therefore, allele frequencies and distributions of the ABO gene can be appropriate indices for investigating the genetic relationships between populations. In this study, to further understand the history and genetic features of human populations in Hokkaido, northern Japan, polymorphisms of the ABO gene in the Jomon/Epi-Jomon and Okhotsk people who lived in Hokkaido were investigated.…”
