What Exactly Is Trisomy 21
Trisomy 21 is a genetic disease where a human being has 47 chromosomes instead of 46 which is the usual or actual number of chromosomes supposed to be in a human body.
This genetic condition is also known as Down Syndrome, and the condition as such can range from person to person and ranges from the mild to the severe.
As far as human birth defects are concerned this Trisomy is the biggest cause by far.
The number 21 has been added to this condition since in most cases there exists an extra copy of chromosome 21 in the body.
Kids with Down Syndrome can be easily recognized.
Some common complications related to this condition are airway blockage during sleep, endocarditis, eye problems, hearing loss, gastrointestinal blockage, regular ear infections, compression injury of the spinal cord, and weakness of the back bones at the top of the neck.
The child should have regular medical checkups if suffering from any or all of the above complications.
Common physical signs include flattened nose, small ears, small mouth, decreased muscle tone at birth, excess skin at the nape of the neck, separated joints between the bones of the skull, single crease in the palm of the hand, upward slanting eyes, white spots on the colored part of the eye known as Brushfield spots and wide, short hands with short fingers.
Kids don't reach their average height and physical changes cum development are quite often slower than normal.
Children may also have impulsive behavior, short attention span, slow learning and poor judgment because of Trisomy 21.
There is no treatment specifically designed for Down syndrome. A baby born with a gastrointestinal blockage may need major surgery soon after delivery. Certain heart defects may also require surgery.
