Multiplex HLA-typing by pyrosequencing.
Class I and II loci of the human leukocyte antigens (HLA) represent the most polymorphic region of the genome. Evolutionary pressure has resulted in a large number of allelic variants of these loci ensuring the high frequency of heterozygous genotypes observed in human populations. Molecular techniques, including sequencing, are capable of precisely defining HLA alleles. Sequencing by synthesis methodology employed by pyrosequencing represents a complementary approach to other molecular methods of HLA genotyping. Out-of-phase sequencing of HLA alleles by pyrosequencing can resolve certain cis/trans ambiguities that would otherwise require the sequencing of cloned DNA. Genotyping of HLA loci for the presence of specific amino acid variants is beneficial for proper matching of organ donor to recipient, the monitoring of HLA associated genetic risk to autoimmune diseases, population genetic studies, as well as evaluation of the genetics of human host-human pathogen interaction.
