IMHO There are two known alleles for the HLA-DRA gene. This information has
been obtained from a new german immunological textbook (Medical immunology ed.
H. Baenkler)
Whether the aminoacid exchange touches the peptide binding groove or belongs
to those amino acids responsible for the TCR binding I donot know.
