Next-generation sequencing (NGS) of HLA class I and II loci (HLA-A, HLA-B, HLA-C, DRB1, DRB3, DRB4, DRB5, DQA1, DQB1, DPB1) is described here in detail using the 454 Life Sciences GS FLX System and Titanium chemistry. An overview of the protocol with our experience on sequence performance efficiencies, read depth and ambiguity analyses using the GS FLX System are also presented. A total of 14 HLA primer pairs with multiplex identifiers (MIDs) are used in clonal, amplicon-based pyrosequencing of up to 44 samples per plate using the GS FLX. Genotype assignment and ambiguity reduction analysis is performed using Conexio Assign ATF 454 software. Clonal NGS gives a significant reduction in genotyping ambiguity during analysis of the highly complex HLA system.
