Genetic Testing Sarah Kistenmacher

Raise your hand if you have ever known someone with a genetic disease

Look around

Nearly everyone has been affected by a genetic disease

Whether an adult family member

Or a childhood friend

I have been affected just like everyone else

My Grandfather Cancer Diagnosed August 1990 Died December 1990

My Father Cancer Diagnosed May 2005 Treated Summer 2005

My Grandmother Cancer Diagnosed August 2002 Treatment Ongoing

My wish is that no one will have to go through the pain and anguish that my family went through

With genetic testing patients could be diagnosed early

Leading to a better prognosis

And less suffering for all affected

To understand genetic diseases and genetic testing we must first understand the structure of DNA
