Newborn screening: should whole genome sequencing be introduced?

Whole genome sequencing is becoming more popular in medical research. With its falling cost and increasing reliability, some scientists hail the process as being the future of genetic research. But should whole genome sequencing be used as a part of newborn screening programs? This is a question that researchers from McGill University in Canada say should be addressed.The human genome is made up of over 3 billion genetic letters - A, C, G, and T. These are known as DNA nucleotides and represent pieces of DNA called adenine, cytosine, guanine and thymine.
