Haplotype-resolved assemblies of the MHC region in five widely used tumor cell lines.

ABSTRACT: The major histocompatibility complex (MHC) region plays a crucial role in immune function and is implicated in various diseases and cancer immunoediting. However, its high polymorphism poses challenges for accurate genetic profiling using conventional reference genomes. Here, we present high-quality, haplotype-resolved assemblies of the MHC region in five widely used tumor cell lines: A549, HeLa, HepG2, K562, and U2OS. Numerous oncological studies extensively employ these cell lines, ranging from basic molecular research to drug discovery and personalized medicine approaches. By integrating CRISPR-based targeted enrichment with 10 × Genomics linked-read and PacBio HiFi long-read sequencing, we constructed MHC haplotypes for each cell line, providing a valuable resource for the research com
