For example, in the case of Down syndrome (trisomy 21), there are three copies of chromosome number 21. Trisomy 21 has a distinct clinical phenotype and varying degrees of cognitive impairment. The majority of cases are detected prenatally, usually with a combination of maternal genetic screening and prenatal ultrasound. The most common structural abnormalities in trisomy 21 are increased nuchal translucency, cardiac defects, and duodenal atresia.
