Don't rely on outdated information about Down syndrome. Gain a clear, modern understanding of this genetic condition, from its causes to its unique characteristics, and learn the real facts to foster true awareness and inclusion for everyone.
What are the main causes of Down syndrome?
- The most common cause is Trisomy 21, a random genetic event where an individual has three copies of chromosome 21 instead of the usual two.
- This extra genetic material alters development, resulting in the characteristics associated with the condition, and it is not caused by any parental behavior before or during pregnancy.
- Less common types include mosaic Down syndrome, where only some cells have the extra chromosome, leading to varied characteristics.
Key characteristics of Down syndrome to watch for
- Common physical traits often include a flattened facial profile, upward-slanting eyes, a single deep crease across the palm of the hand, and shorter stature.
- Individuals typically experience some degree of cognitive delay, but the level of intellectual ability varies significantly from person to person, with many leading fulfilling lives.
- Certain health conditions like congenital heart defects and hearing or vision issues are more common, making regular medical check-ups an essential part of care.
How can you prevent Down syndrome effectively?
- Down syndrome is a naturally occurring chromosomal arrangement that cannot be prevented, as it is typically the result of a random event during cell division.
- While the statistical likelihood increases with maternal age, most babies with Down syndrome are born to mothers under 35 because this age group has more children.
- Prenatal screening tests are available to detect the condition during pregnancy, allowing parents to prepare, but these tests do not prevent the condition itself.
