  • Improved genetic discovery and fine-mapping resolution through multivariate latent factor analysis of high-dimensional traits - Unknown journal (n.d.) · Unknown authors · PubMed 40220762

    ABSTRACT: Summary Genome-wide association studies (GWASs) of high-dimensional traits, such as blood cell or metabolic traits, often use univariate approaches, ignoring trait relationships. Biological mechanisms generating variation in high-dimensional traits can be captured parsimoniously through a GWAS of latent factors. Here, we introduce flashfmZero, a zero-correlation latent-factor-based multi-trait fine-mapping approach. In an application to 25 latent factors derived from 99 blood cell traits in the INTERVAL cohort, we show that latent factor GWASs enable the detection of signals generating sub-threshold associations with several blood cell traits. The 99% credible sets (CS99) from flashfmZero were equal to or smaller in size than those from univariate fine-mapping of blood cell trait

  • A genome-wide association study of blood cell morphology identifies cellular proteins implicated in disease aetiology - Unknown journal (n.d.) · Unknown authors · PubMed 37596262

    ABSTRACT: Blood cells contain functionally important intracellular structures, such as granules, critical to immunity and thrombosis. Quantitative variation in these structures has not been subjected previously to large-scale genetic analysis. We perform genome-wide association studies of 63 flow-cytometry derived cellular phenotypes-including cell-type specific measures of granularity, nucleic acid content and reactivity-in 41,515 participants in the INTERVAL study. We identify 2172 distinct variant-trait associations, including associations near genes coding for proteins in organelles implicated in inflammatory and thrombotic diseases. By integrating with epigenetic data we show that many intracellular structures are likely to be determined in immature precursor cells. By integrating

  • Dense fine-mapping study identifies new susceptibility loci for primary biliary cirrhosis - Unknown journal (n.d.) · Unknown authors · PubMed 22961000

    ABSTRACT: We genotyped 2,861 cases from the UK PBC consortium and 8,514 UK population controls across 196,524 variants within 186 known autoimmune risk loci. We identified three loci newly associated with primary biliary cirrhosis (PBC) (with P<5×10−8), increasing the number of known susceptibility loci to 25. The most associated variant at 19p12 is a low-frequency non-synonymous SNP in TYK2, further implicating JAK/STAT and cytokine signalling in disease pathogenesis. A further five loci contained non-synonymous variants in high linkage disequilibrium (LD) (r2>0.8) with the most associated variant at the locus. We found multiple independent common, low-frequency and rare variant association signals at five loci. Of the 26 independent non-HLA signals tagged on Immunochip, 15 have SNPs i
