Down Syndrome vs. Patau's Syndrome

What's the Difference?

Down Syndrome and Patau's Syndrome are both genetic disorders that result from chromosomal abnormalities. Down Syndrome, also known as Trisomy 21, occurs when an individual has an extra copy of chromosome 21. This condition is characterized by distinct physical features, intellectual disabilities, and an increased risk of certain health problems. On the other hand, Patau's Syndrome, also known as Trisomy 13, is caused by an extra copy of chromosome 13. It is a more severe condition, often leading to severe intellectual disabilities, multiple organ abnormalities, and a significantly reduced life expectancy. While both syndromes have similar origins, Patau's Syndrome tends to have more severe symptoms and a higher mortality rate compared to Down Syndrome.
