In this report, we describe the identification of an human leucocyte antigen-Cw*06 (HLA-Cw*06) nucleotide sequence variant, a new HLA-Cw*0612. The new allele was detected during routine HLA typing by high-resolution sequence-based typing. Allele Cw*0612 showed one nucleotide difference with Cw*0602 at codon 153 (GCG-->ACG) resulting in an amino acid change from alanine to threonine.

In this report, we describe the identification of an human leucocyte antigen-Cw*0102 (HLA-Cw*0102) nucleotide sequence variant, a new HLA-Cw*010203, in a case - control study by using sequence-based typing. Allele HLA-Cw*010203 showed one nucleotide difference with HLA-Cw*010201 by a silent substitution at codon 130 (CTG-->CTA).

In this report, we describe the identification of a human leucocyte antigen-A*11 (HLA-A*11) nucleotide sequence variant, a new HLA-A*1120 by using sequence-based typing (SBT). The new allele was detected during routine HLA typing by high-resolution SBT. Allele A*1120 showed one nucleotide difference with A*110101 at codon 152 (GCG-->GAG) resulting in an amino acid change from alanine to glutamate. Residue 152 is located on alpha(2)-helix of HLA class I molecule and involved in peptide binding by constructing E pocket of peptide-binding groove, implying that the change of the residue 152 would affect the binding affinity of peptides to A*1120 allele.

In this report, we describe the identification of an HLA-A*31 nucleotide sequence variant, a new HLA-A*3111, in three members of a Korean family by using sequence-based typing (SBT). The new allele was detected during routine HLA typing by high-resolution SBT. Allele A*3111 showed one nucleotide difference with A*310102 at codon 165 (GTG-->CTG) resulting in an amino acid change from valine to leucine (V165L). Serologic reactivity was shorter than normally expected.
