By 2030, every baby born in the UK could have their entire genome sequenced under a new NHS initiative to “predict and prevent illness”. This would dramatically expand the current heel-prick test, which checks for nine rare genetic conditions, into a far more extensive screen of hundreds of potential risks.
On the surface, the idea sounds like an obvious win for public health: spot problems early, intervene sooner and save lives. But genetic testing on this scale carries real risks, especially if the results are misunderstood or poorly communicated.
