Patient's question:
A few days ago, I just had a Down syndrome screening, but the doctor said that the baby I am carrying might have a problem, possibly a Down syndrome patient. My body has always been fine, and I want to ask what are the causes of Down syndrome?Doctor's answer:
The cause of Down syndrome is very complex. The main factor to consider is chromosomal abnormalities. If the egg quality is poor, it may also trigger it. If there are any doubts, a review can be conducted. After one week, Down syndrome screening and amniocentesis can be performed for further examination. Most cases of Down syndrome are caused by chromosomal abnormalities. In most patients, there is an error in the inheritance division process of the 21st pair of chromosomes, leading to an extra chromosome in the nucleus. A small portion is caused by translocation.
