T1 - Targeted and complete genomic sequencing of the major histocompatibility complex in haplotypic form of individual heterozygous samples Y1 - 2024/10/01 JF - Genome Research JO - Genome Research SP - 1500 EP - 1513 DO - 10.1101/gr.278588.123 VL - 34 IS - 10 UR - http://genome.cshlp.org/content/34/10/1500.abstract N2 - The human major histocompatibility complex (MHC) is a ∼4 Mb genomic segment on Chromosome 6 that plays a pivotal role in the immune response. Despite its importance in various traits and diseases, its complex nature makes it challenging to accurately characterize on a routine basis. We present a novel approach allowing targeted sequencing and de novo haplotypic assembly of the MHC region in heterozygous samples, using long-read sequencing technologies. Our approach is validated using two reference samples, two family trios, and an African-American sample. We achieved excellent coverage (96.6%–99.9% with at least 30× depth) and high accuracy (99.89%–99.99%) for the different haplotypes. This methodology offers a reliable and cost-effective method for sequencing and fully characterizing the MHC without the need for whole-genome sequencing, facilitating broader studies on this important genomic segment and having significant implications in immunology, genetics, and medicine.
