A recent Wall St Journal interview with J. Craig Venter indicates his company is currently working on translating DNA data into a ‘photo of you’, or the sound of your voice. The logic of course is that genetics (including epigenetic elements) include the parts list, assembly instructions and many of the finishing details for building an individual. So it may not come as a surprise that a DNA sample can identify you as an individual (even distinct from your identical twin — considering mutations and epigenetic variations) — or perhaps even to create a clone. But having a sample of your DNA translated into a picture of your face (presumably at different ages) or an imitation of your voice is not something that had been in my genomic awareness.
The DNA sample from the crime scene may do more than identify the Perp, it may be the basis for generating a ‘police sketch’ of her face.
The movie Gattaca projected a society where genetic evaluation was a make/break factor in selecting a mate, getting a job, and other social decisions. But it did not venture into the possibility of not just the evaluation of genetic desirability of a mate, but perhaps projecting their picture some years into the future. “Will you still need me .. when I’m sixty four?”
The interview also considers some of the ethical issues surrounding insurance, medical treatment and extended life spans … What other non-obvious applications can you see from analyzing the genomes and data of a few million persons?
