The new allele A*02:355 differs from A* 02:03:01 at positions 98 (T→A) and 102(A→C) resulting in an amino acid exchange F9→T. Interallelic sequence exchange is more likely the mechanism of its origination. The amino acid replacement influences the HLA peptide binding cleft and might have significant functional effects.
