Answer
Down Syndrome, also known as congenital idiocy, is a severe congenital malformation. Prenatal screening can detect Down Syndrome around the 16th week of pregnancy. If there are abnormalities, further DNA testing can be conducted to prevent the birth of Down Syndrome children. Prenatal examinations are very important. The causes of this disease are diverse, including factors such as genetic transmission across generations, environmental factors, and early viral infections.
