Human MHC class I genes HLA-A, -B, -C, and class II genes HLA-DR, -DP and -DQ, play a critical role in the immune system as major factors responsible for organ transplant rejection. The have a direct or linkage-based association with several diseases, including cancer and autoimmune diseases, and are important targets for clinical and drug sensitivity research. HLA genes are also highly polymorphic and their diversity originates from exonic combinations as well as recombination events. A large number of new alleles are expected to be encountered if these genes are sequenced through the UTRs. Thus allele-level resolution is strongly preferred when sequencing HLA genes. Pacific Biosciences has developed a method to sequence the HLA genes in their entirety within the span of a single read taking advantage of long read lengths (average >10 kb) facilitated by SMRT technology. A highly accurate consensus sequence (=99.999 or QV50 demonstrated) is generated for each allele in a de novo fashion by our SMRT Analysis software. In the present work, we have combined this imputation-free, fully phased, allele-specific consensus sequence generation workflow and a newly developed DNA-barcode-tagged SMRTbell sample preparation approach to multiplex 96 individual samples for sequencing all of the HLA class I and II genes. Commercially available NGS-go reagents for full-length HLA class I and relevant exons of class II genes were amplified for hi-resolution HLA sequencing. The 96 samples included 72 that are part of UCLA reference panel and had pre-typing information available for 2 fields, based on gold standard SBT methods. SMRTbell adapters with 16 bp barcode tags were ligated to long amplicons in symmetric pairing. PacBio sequencing was highly effective in generating accurate, phased sequences of full-length alleles of HLA genes. In this work we demonstrate scalability of HLA sequencing using off the shelf assays for research applications to find biological significance in full-length sequencing.
