Patient's question:
My sister is 26 years old and more than 16 weeks pregnant. She went for a prenatal check-up recently, and the doctor said her baby was not developing well inside the womb. She was advised to have a Down syndrome screening. The results came out two days ago, and it said low risk for trisomy 21. What is trisomy 23?Doctor's answer:
21-trisomy syndrome, also known as Down syndrome or congenital idiocy, is the earliest discovered chromosomal disease. Its main clinical diagnostic symptoms include significant growth and development delays, along with a higher incidence of deformities such as limb deformities and congenital heart disease. Additionally, individuals with this condition often have a distinctive facial appearance. This appearance may include wide-set eyes, a low and flat nose bridge, a large tongue that is often protruding outside the mouth, and excessive drooling.
