Down Syndrome

By: Alex Calderon

How the child gets it?

Down Syndrome is caused by a pair of chromosomes failing to separate during egg/sperm formation. When the egg connects with a regular sperm cell to form an embryo, it ends up with three copies of chromosome 21 instead of two.

Symptoms and characteristics of Down Syndrome

-decreased or poor muscle tone

-short neck, with excess skin behind the neck

-flattened facial profile and nose

-small head, ears and mouth

-upward slanting eyes, with a skin fold that covers the corner of the eye


There are no medications or therapy for Down Syndrome. The most that can be done to insure a healthy baby is to have frequent doctors visits.
