Antenatal diagnosis of genetic disorders requires the acquisition of fetal or placental tissue. Invasive procedures are indicated if a fetus is at increased risk for a genetic condition. Risk factors include advanced maternal age, known parental genetic conditions, abnormal aneuploidy screening, soft markers for aneuploidy on ultrasound, and fetal growth restriction .
