HLA Alleles
Numbers
Assigned
January 2010
The numbers below represent the number of named
alleles for each gene. This number includes alleles which have
been named but whose sequences is still held as confidential,
this means that the number of sequences found in some files on this site may differ to the
numbers printed in this table. Details of which alleles are still
confidential can be seen in the latest version
reports on the IMGT/HLA
Database web site. The numbers below do not include the names of
any deleted alleles, further details of which deleted alleles can be
found in a separate report.
