What is the disease and what are the signs/symptoms that someone has the disease?
• It is a genetic condition that effects about every 1 in 733 babies
• Genetic condition- something that you are born with
• You cannot catch this disease from someone who has it, not able to be passed on
• One of the ways to tell if someone has it is to look at the way they look (face is rounder and flatter and eyes may slant a little)
• They are effected on how quickly that they learn new information

• People with other problems like autism or Cerebral Palsy as well as DS have more difficulties with learning things
• The extra chromosome also affect the persons physical looks
• There are 3 types:
1. Trisomy 21-most common 95% of people with Down Syndrome have it, it is when the person only gets 1 copy of chromosome 21 in their cells
2. Translocation Down Syndrome- approximately 4% of people with Down Syndrome have it, it is where the person gets 2 copies of chromosome 21 in their cells
3. Mosaicism (Mosaic) Down Syndrome- the last 1% of people with Down Syndrome have this, in this type the body cell’s have 3 copies of chromosome 21 in their cells, where the areas typically have 2

What can be done to help them with their disease or the symptoms (such as: medicines, nutrition, or a physical treatment etc…)

How is it inherited? Is it a mutation? Is it passed down on a specific chromosome? Does it tend to run in families? (What is known at this time?)
• The people with Down Syndrome get it because they have an extra chromosome, they have 47 instead of 46
• The other name for Down Syndrome is Trisomy 21
• It is passed down on chromosome number 21
• Yes, this disease is a mutation because it is caused by a
