Singapore Integrative Omics Study: Establishing multiple omics baselines for three Southeast Asian populations

In this study, we aim i) to establish population reference measurements across multiple omic technologies; ii) to investigate the inter-population variations in each omic and phenotypic measurements in three major populations in Singapore. The measurements include:

  1. more than 2.5 millions SNPs across the genome (including exonic and pharmacogenomic SNPs);
  2. 4-digits typing alleles at eight HLA loci;
  3. 21,649 gene probesets expression;
  4. 282 lipid species via mass spectometry;
  5. 274 circulating miRNAs via qPCR quantification; and
  6. 284 phenotypic variables (including clinical, lifestyle and dietary variables)
