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, including heart defects, kidney problems, and growth deficiencies. Most affected infants have a low birth weight and may have distinctive features such as a small head, clenched fists, and overlapping fingers. The prognosis for individuals with Edwards syndrome is generally poor, with many affected babies not surviving past their first year of life. Those who do survive often face significant health challenges and require ongoing medical care and support. Early diagnosis and intervention can help manage some of the associated complications.
