Down syndrome is a genetic disorder primarily caused by gene mutations, mainly resulting from chromosomal abnormalities, specifically having an extra 21st chromosome. In addition to gene mutations, factors such as advanced maternal age, exposure to radiation and chemicals, can increase the risk of occurrence. The symptoms of Down syndrome children include difficulty in normal communication, inability to participate in regular physical activities, and involuntary drooling. During pregnancy, it is essential to undergo Down syndrome screening, making it a crucial part of prenatal examinations. It is an effective preventive measure to reduce the incidence of Down syndrome and ensure the birth of a healthy baby. It is recommended that expectant mothers undergo prenatal examinations on schedule to reduce the risk of Down syndrome and give birth to a healthy child.
