22. Transfection Results (A2 and A3 Alleles)

 

When A201 allele-specific mutations (P156L and 1060delC) or the single nucleotide deletion (1060delC) were introduced into the A101 construct, A antigen expression did not disappear but did diminish. The A301 allele-specific amino acid substitution (D291N) also diminished given A antigen expression (Yamamoto, 1995).
