Abstract

OBJECTIVETo confirm a new allele HLA-B*13:01:06 and analyze its nucleotide sequence.

METHODSGenomic DNA was extracted using a Qiagen DNA extraction kit. Nucleotide sequences of HLA-A, HLA-B, HLA-C and HLA-DRB1 were analyzed by polymerase chain reaction-sequence based typing (PCR-SBT). HLA high-resolution results were assigned, and the nucleotide sequences of HLA-B locus was compared with that of HLA-B*13:01:01.

RESULTSThe nucleotide sequence of the new allele shows a strong similarity to that of HLA-B*13:01:01. One nucleotide in exon 2 has changed from G to A at position 219 (codon 49 GCG>GCA), which however did not result in amino acid change.

CONCLUSIONThe novel allele verified by sequencing has been submitted to GenBank and officially named as HLA-B*13:01:06 by the World Health Organization HLA Nomenclature Committee.
