HPA Gene Database

The following table details genetic information about HPA Antigens. The following conventions are used in the table:

Nucleotide numbers are given in relation to the reference sequence in the NCBI database, as indicated in the RefSeq column, and we have used the numbering convention as recommended by Antonarakis (Hum Mutat 1998;11:1-3) whereby the A of the start codon is +1.
Nucleotide and protein substitutions are shown as changes from the higher frequency (a) allele to the less common (b) allele. In certain cases, e.g. HPA-5, the reference sequence encodes the less common form.
