Edwards Syndrome, also known as Trisomy 18, is a genetic disorder caused by the presence of an extra 18th chromosome. This condition leads to severe developmental delays and various physical abnormalities. Common features include a small head, clenched fists, and heart defects. Most affected infants have a short life expectancy, with many not surviving past their first year. Diagnosis of Edwards Syndrome can be made through prenatal testing, such as amniocentesis or chorionic villus sampling. While there is no cure, supportive care can help manage symptoms and improve quality of life for those who survive longer.
