We brought in a screening programme that tests for trisomy-21, trisomy-18, and trisomy-13. But what I've neglected to do is actually talk about what those conditions are. And I actually think it's really important people know what we're talking about. So trisomy-13 was discovered by Dr Klaus Patau in 1960, and essentially it means that the fetus has extra genetic material. They have disrupted normal development, causing multiple and complex organ defects. Ninety percent of the children born with Patau syndrome die within the first year. They have intellectual disabilities, they have seizures, and they require surgical intervention. So our publicly funded screening programme at 14 weeks and 20 weeks provides information like this to parents.
