Question
What are the dangers of children with Down syndrome? Can doctors explain the severity of this condition in detail?
Answer
Down syndrome, also known as trisomy 21 or trisomy syndrome, is a common birth defect disease caused by chromosomal abnormalities in children. Approximately 60% of fetuses with this condition experience early miscarriage, while those who survive may exhibit significant mental development delays, distinctive facial features, growth and development disorders, and various malformations. Boys with Down syndrome usually have no fertility after puberty, while girls may have menstrual periods and have the potential for fertility in adulthood.
