Patient's question:
A friend's child has been developing slowly and looks quite strange. The doctor said the child has Down syndrome. What causes Down syndrome?Doctor's answer:
Most patients have a second error in the twenty-first chromosome during the intergenerational genetic differentiation, which induces extra chromosomes in the nucleus; a small number are caused by translocation. The child is affected by Down syndrome, so parents must take the child to see a doctor immediately for treatment to prevent blind medication from alleviating symptoms. For parents, it is important to carefully observe changes in the child's symptoms and do their best to help the child receive timely treatment for the disease.
