  1. Major T, Topless R, Dalbeth N, Merriman T. Evaluation of the diet wide contribution to serum urate levels: meta-analysis of population based cohorts. BMJ. 2018;363:k3951 pubmed publisher
    ..9% of variance in serum urate levels was explained by common, genome wide single nucleotide variation. In contrast with genetic contributions, diet explains very little variation in serum urate levels in the general population. ..

  6. Merriman T. Genomic Influences on Hyperuricemia and Gout. Rheum Dis Clin North Am. 2017;43:389-399 pubmed publisher
    ..However identification of causal genes at other urate loci is challenging. Finally, relatively little is known about the genetic control of progression from hyperuricemia to gout. Only 4 small GWAS have been published for gout. ..
  7. Merriman T. Population heterogeneity in the genetic control of serum urate. Semin Nephrol. 2011;31:420-5 pubmed publisher
    ..A more complete picture will be revealed by very large meta-analyses of genome-wide association scans in Caucasian and in other populations with less genetic heterogeneity than Caucasians. ..

    ..10). Our data, replicating a previous study, supports the hypothesis that the apolipoprotein A1-C3-A4 gene cluster plays a causal role in gout. ..
