Concept of MolPAGE

MolPAGE

MolPAGE

“GENOMIC EPIDEMIOLOGY”

measurement, manipulation and analysis of “omics” scale data in thousands of subjects

Page 4: FP6 “Molecular Phenotyping to Accelerate Genomic Epidemiology”

Programme Goals

“The application of genomic, metabonomic and proteomic tools to develop novel technical, data analysis and integration

protocols that will enable disease biomarker typing and discovery

projects on an epidemiological scale”

“The identification and validation of biomarkers for use as

pre-clinical predictors of metabolic disease”

Page 5: FP6 “Molecular Phenotyping to Accelerate Genomic Epidemiology”

Programme Overview

1. The evaluation of sample collection and storage methodology;

• to optimally reduce sample variation and maximise analyte stability2. The development of genomic, metabonomic and proteomic tools;

• to prepare for molecular phenotyping on an epidemiologic scale • relevant to both biomarker discovery and subsequent biomarker

measurement in large sample sets• Includes proof of principle biomarker discovery (medium-scale)

3. The development of project specific tools to support data warehousing, data interrogation and statistical analysis

• integrated approaches to data analysis across multiple platforms

• integrated approach to data storage and dissemination

Some vignettes

Page 8: FP6 “Molecular Phenotyping to Accelerate Genomic Epidemiology”

1. Standardisation

• Contribute to efforts to standardise sample collection strategies for genomic epidemiology: “future-proofing” biobank collections for future analysis. Build on UK Biobank efforts in this respect….

• Contribute to efforts to generate standards and norms for genomic epidemiology * study design and analysis * sample collection, processing and storage * measurement of exposure and clinical phenotypes * data formats, management, manipulation and storage * analyte measurement (-omics scale) * ethics, data privacy, material transfer * meta-data • To ensure that in 5 years from now, it will be much easier to work across multipleEuropean biobanks than currently….

2. Sources of variation in omics data

• UK TWIN STUDY• Twin volunteers recruited through

media campaigns• Healthy adult population 18+• Representative of UK pop• 500 MZ and 1,500 DZ pairs seen

clinically in detail• Body comp DEXA fat total and

central, fasting glucose,insulin,leptins, lipids

• >10000 twins on database with questionnaire data

• All will have fresh DNA & fasting blood by 2007
