Identification of a Novel HLA ‐ DPA1 Allele With a New Amino Acid Residue in the Core Domain, HLA‐DPA1*01:249

Key Points

• The aim is to characterize a newly identified HLA-DPA1 allele, DPA1*01:249.
• Identification of the novel allele through sequence analysis.
• Characterization based on amino acid composition and structure.
• Discovery of the DPA1*01:249 allele with a unique amino acid residue.
• Characterization highlights differences in the core domain compared to other alleles.
