A novel HLA B*40 allele, B*40:01:40, identified in a Chinese individual
A new allele, officially named B*40:01:40, was detected in a Chinese individual by sequence based typing (SBT) The new allele differs from B*40:01:01 by a single nucleotide exchange at position 99 in codon 9, which results in synonymous substitution and seems not to compromise the HLA complex and T cell receptor interaction.
