Question
What is the probability of recurrence for Down syndrome?
Answer
Down syndrome, also known as trisomy 21, congenital idiocy, or Down syndrome, is a disease caused by chromosomal abnormalities (an extra 21st chromosome). 60% of affected children are aborted in the early stages of pregnancy, with survivors exhibiting significant intellectual disabilities, distinctive facial features, growth and development disorders, and a tendency to develop malformations. If your current pregnancy is relatively stable, do not worry excessively. Pay attention to rest, enhance nutrition, consume more vitamin-rich foods, and strive for a balanced diet. It is recommended to undergo regular detailed examinations at the hospital during the pregnancy process. Generally, an NT scan is recommended at 12 weeks, a Down syndrome screening at 16 weeks, and a 4D ultrasound at 24 weeks. If there are any issues, they can be addressed promptly.
