Show transcript
Some alleles are associated with conditions that affect people’s health (e.g. cystic fibrosis).
Prospective parents can be tested for these alleles, as can embryos (embryo screening).
A fetus can be tested for these alleles (e.g. by chorionic villus sampling or amniocentesis).
Tests can have false negative or false positive results, and risks of miscarriage or infection.
Parents must be supported to interpret test results, consider ethical questions and make difficult personal decisions.
