Genetic Exceptionalism?
Standard of care (non-genetic): Sedentary? Statins? Vegan? Aspirin? Wine? Cell-phones? Cars?Very small odds-ratios, aimed at public health rather than individuals
Conventional clinical genetics: PKU, BRCA1 .. 1361 genes (+5/week) > 4M babies/yr in USA Highly predictable & huge impact.
Why shouldn’t genetics deal with small (uncertain) risk factors like the rest of medicine?

6 of the first 8 full diploid genomes are non-anonymous

Trends toward opennessHR 2764 “SEC. 218. all investigators funded by the NIH submit .. an electronic version of their final, peer-reviewed manuscripts .., to be made publicly available” (make science paid for by tax-payers accessible to the tax-payers, not just the experts)
PatientsLikeMe.com: MS, Parkinson’s, ALS, Depression, Anxiety, Bipolar, OCD, HIV/AIDS “sharing your healthcare experiences and outcomes is good.” (Full names & photos)

Is promising anonymity realistic? Are we in denial?
Trends in laws to make data public (not just at elite institutions): e.g. H.R. 2764, SEC. 218. 26Dec07 open-access for all NIH-funded research. SEC, GINA, etc
(12) Identify individual case/control status from pooled SNP data Homer et al PLoS Genetics 2008
(11) Re-identification after “de-identification” using public data. Group Insurance list of birth date, gender, zip code sufficient to re-identify medical records of Governor Weld & family via voter-registration records (1998)
Self identification trend (genome-altruists)(10) Unapproved self-identification. e.g. Celera IRB. (Kennedy Science. 2002) (9) Obtaining data about oneself via FOIA or sympathetic researchers. (8) DNA data CODIS data in the public domain. even if acquitted

Is promising anonymity realistic? Are we in denial?
Accessing “Secure data”(7) Laptop loss. 26 million Veterans' medical records, SSN & disabilities stolen
Jun 2006. (6) Hacking. A hacker gained access to confidential medical info at the U.
Washington Medical Center -- 4000 files (names, conditions, etc, 2000)(5) Combination of surnames from genotype with geographical info An
anonymous sperm donor traced on the internet 2005 by his 15 year old son who used his own Y chromosome data.
(4) Identification by phenotype. If CT or MR imaging data is part of a study, one could reconstruct a person’s appearance . Even blood chemistry can be identifying in some cases.
(3) Inferring phenotype from genotype Markers for eye, skin, and hair color, height, weight, geographical features, dysmorphologies, etc. are known & the list is growing.
(2) “Abandoned DNA bearing samples (e.g. hair, dandruff, hand-prints, etc.) (1) Government subpoena. False positive IDs and/or family coercion

Personal Genomics Scope (& Issues)
• Ancestry (paternity)• Forensics (abandoned DNA)• Research (anonymity issues)• Science education/curiosity (more) • Microbes, immune, RNA, cancer (more research)• Investment preview (early adopters: cf. fax, PC, www)• Medically actionable given new research or personal data• Medically actionable immediately (setting data thresholds) (1361 clinical diseases in genetests.org 16-Nov-2008)
