What is another widely recognized name for Trisomy 21?

• A. Angelman Syndrome
• B. Down syndrome
• C. Prader-Willi Syndrome
• D. Williams Syndrome

Answer: (B)

Trisomy 21 is most widely recognized as Down syndrome. This genetic disorder occurs when there is an extra copy of chromosome 21, which affects the individual's physical and cognitive development. The presence of this additional chromosome leads to various characteristic features, such as distinct facial appearance, developmental delays, and other health-related issues. The term "Down syndrome" honors John Langdon Down, the physician who first identified the condition in the 19th century. While other options list different genetic disorders, they are not related to Trisomy 21. For example, Angelman Syndrome, Prader-Willi Syndrome, and Williams Syndrome each involve different chromosomal abnormalities and present unique clinical features. Understanding the specifics of Trisomy 21 helps in recognizing it as Down syndrome, which is essential for diagnosis and subsequent care management in neonatal and pediatric transport contexts.
