The numbers below represent the number of named alleles for each gene. This number includes alleles which have been named but whose sequences are still held as confidential. This means that the number of sequences found in some files may differ to the numbers printed in this table. Details of which alleles are still confidential can be seen in the latest version report. The numbers below do not include the names of any deleted alleles - details of deleted alleles can be found in a separate report.
