Goal is to Determine Whether Using Personal Genome Information Will Be Useful In Medicine?

Correlations in Observational Data

Observational Data Can Be Useful

“American Family Study”

“We desperately need, in this country, a large-scale, prospective, population-based cohort study. And we need to enroll at a minimum half a million people. We would need to have their environmental exposures carefully monitored and recorded, their DNA information recorded, their electronic medical records included, and have them consented for all sorts of other follow-ups.”

Generate list of Health Condition/Genetic variant papers

Selection criteria for Genetic Variant:

•Replicated associations•Adequately sized studies•On Affymetrix 6.0 GeneChip (currently)

Final list of Health Condition/Genetic variants

Selection of Health Condition:

•Health conditions only (no Traits)•Is disease potentially ‘actionable’?•Assess by review of medical society policies and recommendations

CPMC Risk Reporting

Risk Estimation

Evaluate Study Design and Size Select study that will provide most representative and valid risk estimates

Assess Study Quality Evaluate methods used for determining phenotype and genotype

If study reports relative risk – report risks directly

If study reports odds ratios – estimate relative risk and report estimated risks

What do participants do after viewing their results?

• They can invite their physician or members of their family to register to view their personal risk information through the web portal

• They may decide to make changes to their lifestyle to try to lower their risk of the health condition.

• They may decide to talk to their physician about their risk of the health condition.

• They can request genetic counseling at CPMC to discuss their risks, at no charge

• CPMC will send them period emails asking them to log onto their web portal account and complete short questionnaires about what they did with their results

What research will be done with CPMC data?

• CPMC scientists, health researchers and biostatisticians will determine whether giving people information about their genetic risk alters their health behavior or their health.

– Outcome surveys, annual MFLQ, medical records

• CPMC scientists will assess the genetic knowledge of CPMC participants during the course of their participation in the study.

– Voluntary genetic knowledge survey

• The broader scientific community will have access to genotypic and phenotypic data from those individuals who opt to release their de-identified data for biomedical research.

(assessed by coded tests/procedures/referrals) when the physicians have

or have not received training in genomic medicine.

Study Aims• Assess motivations to participate in the CPMC and

perceptions of the utility of personalized medicine– Recruit potential “early adopters” to complete an anonymous survey

from among those who sign up to attend a CPMC enrollment event

• Explore participant understanding of personalized genomic disease risk results, intended and actual use of information and educational needs of individuals receiving results– Interview with CPMC participants (n=60)

• Develop possibly recommendations for the ethical offering of personalized genomic disease risk assessment
