Question

The newborn has red spots on the body and is vomiting. What is Trisomy 21 syndrome?

Answer

Trisomy 21 syndrome is a chromosomal abnormality disease caused by the failure of the 21st chromosome to separate during oocyte meiosis, resulting in the embryo having three copies of chromosome 21, which in turn affects normal physical development. Symptoms may include intellectual disability, distinctive facial features, and delayed growth and development. If an abnormal symptom is found in a newborn, it is important to seek medical attention for diagnosis and treatment as soon as possible.
