Population Sequencing Reveals EBV DNA Persistence

It looks like your input was cut off mid-sentence. From what you’ve provided, the passage discusses the challenges in resolving associations between the HLA locus and immune-mediated complex traits, due to factors like allelic diversity, population heterogeneity, and the lack of well-estimated antigens.

Here’s a brief summary of the passage so far:

• The HLA locus is tightly linked to immune-related traits, but understanding the specific associations is difficult.
• The Epstein-Barr Virus (EBV) proteome provides a set of candidate antigens that interact with these HLA alleles.
• Because these alleles variably present EBV antigens, this affects the presence of EBV DNAemia (presence of EBV DNA in blood).
• The researchers assembled four-digit HLA allele data from donors of Non-Finnish European (NFE) or European (EUR) ancestry from UK Biobank (UKB) and All of Us (AOU) cohorts.
• They performed multivariate regression to find associations between HLA alleles and EBV DNAemia.
• They identified 42 associated HLA alleles in total (18 class I and 24 class II alleles) with a nominal P-value threshold (not fully detailed due to cutoff).
