HPA Allele Frequencies

The following tables give the frequencies of the HPA alleles.

The authors of these pages welcome submissions of HPA population data from any laboratory. If you would like to contribute data please send it to pmetcalfe@nibsc.ac.uk or naw23@cam.ac.uk.

Due to the size of the table, a number of columns are hidden by default. To view further information simply click the checkbox for that column. To hide any information uncheck the appropriate box. Internet Explorer users with Windows XP Service Pack 2 should be aware that these pages require active content and should select the appropriate options in order to allow this page to function correctly. These pages do not access any information on your computer, the active content allows you to show/hide columns to reduce the width of the table displayed. These pages have been tested with Internet Explorer (PC), Firefox and Safari. They will not work with older version of Netscape (4.7 and below) and Internet Explorer on Mac.
