Question
A few days ago, I just had a Down syndrome screening, but the doctor said that my baby may have a problem, possibly a child with Down syndrome. I’ve never had any health issues. I would like to ask what causes Down syndrome?
Answer
The causes of Down syndrome are complex, primarily involving chromosomal abnormalities. Poor egg quality may also trigger it. If there are any doubts, a review can be conducted. One week later, Down syndrome screening and amniocentesis can be performed for further examination. Most cases of Down syndrome are caused by chromosomal abnormalities. In most patients, the 21st pair of chromosomes is incorrect during the process of genetic division, leading to the appearance of extra chromosomes in the cell nucleus. A small portion is caused by translocation.
