Answer:

The use of PCR in diagnosing genetic disease, whether inherited genetic changes or as a result of a spontaneous genetic mutations, is becoming more common. Diseases can be diagnosed even before birth. Examples include:

Genetic counselling – screening the parents for genetic disease before deciding on having children

Preimplantation diagnosis – screening for genetic disease before implantation of an embryo in IVF (in vitro fertilisation)

Screening for genetic disease before birth using tissue samples from the chorionic villus (the membranes found between the mother and unborn baby); foetal tissue from the amniotic fluid (the fluid around the unborn baby); or the small quantities of foetal DNA (DNA from the unborn baby) found in the mother’s bloodstream

Diagnosing inherited or spontaneous diseases, either as a result of symptoms, or because of family history (e.g. Duchenne muscular dystrophy)
