What is Down Syndrome?
Down syndrome is the most common cause of mental retardation and malformation in a newborn. Down syndrome occurs because of the presence of an extra 21st chromosome.
Chromosomes are the materials that store people's genetic information. Each person inherits 23 chromosomes from their mother and twenty three chromosomes from their father. Sometimes an accident occurs and one of the parents gives an extra chromosome. When the extra chromosome happens to be chromosome number 21, Down Syndrome occurs.
Down Syndrome is not contagious.
Down syndrome is also called trisomy 21.
