When babies become intensely ill, it can be difficult to know what has gone wrong. But the answer, quite often, is hidden somewhere in their genes.
Whole-genome sequencing — in which scientists can read the nearly 3 billion chemical letters in DNA — can help turn up that answer. And scientists, increasingly, are laying out a case for using that tool in an intensive care setting, despite the upfront costs.
With genome sequencing, some sick infants are getting a shot at healthy lives
