To query the status of an allele, select the gene and enter the allelic designation. The "Allele" field will automatically match any allele that begins with the entered query e.g. entering "02" and searching the "A" gene would return all A*02 alleles. Use the "Display" field to specify whether only partial sequences, only unconfirmed sequences, or all sequences are displayed in the results.

Gene Allele Display Search
  • An allele is listed as a "Partial" sequence if the DNA sequence held is shorter than the respective reference sequence.
  • An allele is listed as Confirmed if it has been sequenced by more than one laboratory and/or from multiple sources (different cells or DNA samples). Alleles confirmed from multiple sources may originate from a single laboratory.
