Scientific Strategy and Cohort Enhancements

Charge / Overview

Develop a scientific agenda to identify novel approaches to diagnose and treat genomic conditions, explore enhancements to existing cohorts, and address diversity gaps

Core Initiatives

  1. Improve the diagnosis, prognosis and treatment of complex diseases, both common and rare
  2. Identify high-risk individuals through the following methods:
    • Genotypic risk scores
    • Homozygous loss of function (LoF) variants
    • Cross-cohort genetic meta-analysis of molecular ‘omics
    • Copy number variation (CNV); phenome-wide association study (PheWAS)
    • Cross-cohort genetic array analysis of uncommon outcomes
    • Identify ultra-rare variants, mitochondria, expression quantitative trait loci (eQTL), epigenetics and apply Mendelian randomization
  3. Improve understanding of variability in response to treatments and identify novel pharmacogenetic (PGx) associations
  4. Design a strategy for genomic enhancement to cohorts that allows countries/regions that have large cohorts with environmental data samples but limited resources for sequencing to generate genomic information
    • Identify resources needed to turn samples into data
    • Address the “diversity gap” in genomics and focus on whole genome sequencing (WGS) in low and middle income countries (LMIC):
  5. Explore enhancements to existing cohorts/datasets:
    • Scope molecular ‘omics platforms for implementation
    • Examine use of digital health devices (i.e., Fitbits, etc.)
    • Explore utility information based on patient reported/entered data to fill in phenotypic gaps
  6. Create an integrated ‘omics workspace to allow for integrative omics analyses

Why Do I need to Register ?

We are asking for this information in order to measure where the questionnaire is being used, and by whom.

We may follow-up with you in the future for additional feedback on how you have used questionnaire.

We will not use your email address for marketing, and will not share it with any third parties. 

Core COVID-19 Phone Survey Downloads​​

The PDF and Rich Text (Word doc compatible) documents, include the core survey questions, which should be customized for local administration.

The CSV file contains the REDCap data dictionary, containing all core questions and skip logic. It should also be customized for local administration.

Ancillary questions are not part of the core questionnaire, but can be used for additional data capture.

If using the questionnaire, please include the citation on the previous page. If you have any questions about the survey, please contact John Connolly.
