Only one sequence for each allele is shown. This set of sequences is part of the IMGT reference directory.
Other known sequences are shown in the individual Alignments of alleles

When several alleles are shown, the nucleotide mutations and amino acid changes for a given codon are indicated in red letters. These polymorphic mutations are reported in Tables of alleles.
Dashes indicate identical nucleotides. Dots indicate gaps by comparison to the longest sequence. Blanks indicate partial sequences (blanks at the 5' and/or 3' end).

The F, G and G of the FGXG motif are shown in brown, in the allele *01 amino acid sequence.
