Identification of the novel HLA-C*04:495 allele by sequencing-based typing.

The HLA-C*04:495 allele differs from HLA-C*04:01:01:31 by two nucleotide changes in the 5'UTR and exon 5.

Identification of the novel HLA-A*74:03:03 allele by sequencing-based typing.

HLA-A*74:03:03 differs from A*74:03:01 by a synonymous mutation at nucleotide 1948 in exon 4.

Characterization of the novel HLA-B*57:02:01:03 allele by sequencing-based typing.

Two-nucleotide changes in the 3' UTR of HLA-B*57:02:01:01 result in the novel HLA-B*57:02:01:03 allele.
