antenatal screening programme

T18 and T13

This recommendation has been archived and is no longer regularly reviewed by the UK NSC.

Edwards' Syndrome (Trisomy 18) and Patau’s syndrome (Trisomy 13) are rare but very serious conditions which affect a small number of babies every year. They are caused (like Down’s syndrome) by the baby having an incorrect number of chromosomes in every cell. Chromosomes are structures that carry important information that determine how we develop.
