Nomenclature for factors of the HLA system, update August 2013

Detection of HLA-C*12:109, an HLA-C*12 variant, in a Taiwanese hematopoietic stem cell donor

Nucleotide replacement in codon 194 of HLA-C*12:03:01:01 results in a novel allele, HLA-C*12:109.

Three new HLA-C alleles (HLA-C*14:02:13, HLA-C*15:72 and HLA-C*15:74) in Saudi bone marrow donors

Three new HLA-C alleles were identified by sequence-based typing method (SBT) in donors for the Saudi Bone Marrow Donor Registry (SBMDR). HLA-C*14:02:13 differs from HLA-C*14:02:01 by a silent G to A substitution at nucleotide position 400 in exon 2, where lysine at position 66 remains unchanged. HLA-C*15:72 differs from HLA-C*15:22 by a nonsynonymous C to A substitution at nucleotide position 796 in exon 3, resulting in an amino acid change from phenylalanine to leucine at position 116. HLA-C*15:74 differs from HLA-C*15:08 by a nonsynonymous C to T substitution at nucleotide position 914 in exon 3, resulting in an amino acid change from arginine to tryptophan at position 156.

A new HLA-A*03 null allele - A*03:162N caused by an exon 4 insertion and discovered during an external quality assessment exercise

HLA-A*03:162N differs from A*03:01:01:01 by an exon 4, 664-665insCATG causing E198A and A199X.
