Genomics-based personalized medicine promises to revolutionize survival across a spectrum of conditions, thanks to its ability to predict disease in an individual and then tailor their treatment.
In particular, cancer patients are already benefiting. But accuracy depends on the evaluation of the patient's personal genetic information against as many other genomes as possible.

Home testing kits often rely on a relatively small and occasionally outdated bank of genetic data, RCGP experts warned on Friday
. Helen Stokes-Lampard, chairman of the Royal College of Physicians, said: "Genomic data certainly play a vital role in the care we provide to patients in the future – and in some cases it already is.
" But we have concerns about genetic direct consumer testing, which is increasingly commercially available, with results that are not reliable enough and may cause unnecessary anxiety or inappropriate comfort. "
Experts advise families of patients with rare and difficult to diagnose are conditions to seek advice from charities instead of rning to kits.
