Abstract excerpt
BACKGROUND: The cis-AB phenotype is very rare, and only three genotypes that correspond to specific ABO allele changes have been reported. Cis-AB01 involves the A102 allele with a nonsynonymous substitution G803C in exon 7, whereas cis-AB02 and cis-AB03 involve different nonsynonymous substitutions A796C and C700T, respectively, on the B101 allele background. The nucleotide substitutions give rise to a change of...
