The three classes of genes that comprise the MHC gene family are actively involved in determining donor-recipient compatibility for organ transplant, as well as susceptibility to autoimmune diseases via cross-reacting immunization. Specifically, Class I genes HLA-A, -B, -C, and class II genes HLA-DR, -DQ and -DP are considered medically important for genetic analysis to determine histocompatibility. They are highly polymorphic and have thousands of alleles implicated in disease resistance and susceptibility. The importance of full-length HLA gene sequencing for genotyping, detection of null alleles, and phasing is now widely acknowledged. While DNA-sequencing-based HLA genotyping has become routine, only 7% of the HLA genes have been characterized by allele-level sequencing, while 93% are still defined by partial sequences. The gold-standard Sanger sequencing technology is being quickly replaced by second-generation, high- throughput sequencing methods due to its inability to generate unambiguous phased reads from heterozygous alleles. However, although these short, high-throughput, clonal sequencing methods are better at heterozygous allele detection, they are inadequate at generating full-length haploid gene sequences. Thus, full-length gene sequencing from an enhancer-promoter region to a 3’UTR that includes phasing information without the need for imputation still remains a technological challenge. The best way to overcome these challenges is to sequence these genes with a technology that is clonal in nature and has the longest possible read lengths. We have employed Single Molecule Real-Time (SMRT) sequencing technology from Pacific Biosciences for sequencing full-length HLA class I and II genes.
