Implication

Genomic characterization reveals a novel HLA-DQA1*01:203 allele distinguished by a single nucleotide substitution in exon 1, expanding known human leukocyte antigen diversity.

Key Points

Identify and characterize the sequence variation defining the novel HLA-DQA1*01:203 allele.
Analyzed genomic DNA using sequencing-based typing to determine the nucleotide sequence of the novel HLA-DQA1 allele.
HLA-DQA1*01:203 differed from the closely related HLA-DQA1*01:02:01:01 allele by a single nucleotide substitution.
The point mutation was mapped specifically to codon -18 located within exon 1.
