The entire DNA of 100,000 newborns in England is to be sequenced as part of a research project to improve the diagnosis and treatment of rare genetic conditions.
It will be the first time that whole genome sequencing (WGS) has been offered to healthy babies in the NHS.
The Newborn Genomes Programme will screen for around 200 disorders, all of them treatable.
It is thought to be the biggest study of its kind in the world.
The project, which will begin next year, will be led by Genomics England, in partnership with the NHS. If successful, it could be rolled out across the country.
Currently, a heel prick blood test offered to newborns screens for nine rare conditions, including cystic fibrosis and sickle cell disease.
Dr Rich Scott, Chief Medical Officer for Genomics England, said: “Our goal is… to do more for the thousands of children born every year in the UK with a treatable genetic condition.
“We want to be able to offer speedy diagnosis, quicker access to treatment, and better outcomes and quality of life.”
