Down Syndrome, also known as Trisomy 21, is one of the most common abnormal birth defects causing delay in physical and intellectual development (Facts About Down Syndrome). It involves having an extra copy of chromosome number 21. There are 23 sets of chromosomes, each set containing two chromosomes. Babies with Down Syndrome will have a total of 47 chromosomes instead of 46 (Facts About Down Syndrome). Chromosomes are threadlike, genetic structures carrying genetic information and are found in the nucleus of every cell in the body.
Down Syndrome is not a condition that can be cured, however there is treatment to help patients live productive lives (Shriver 2007). Children with the condition can benefit from organizations put together in their community, or school. Most children receive help with speech therapy, exercise to refine motor skills, and some even enroll in regular classes at school (Shriver 2007).
