What are Genetic Disorders?  Genetic disorders are illnesses stemming from errors in a person’s genes  Any mistake in a gene can alter how a specific protein is produced  Without proper proteins, the body will not function properly and will take on a chronic and possibly life threatening condition

How is it Caused?  Genetic disorders can be congenital meaning they occur from birth or they may develop over time  Congenital disorders occur when parents who are carriers of the disorder pass on their genes to their children  Progressive disorders that take time to set in may be caused by a mutation in DNA

What is Gene Therapy?  Gene therapy is the process of taking DNA coded for specific genes and adding it to a person’s genome in efforts to treat and alleviate genetic disorders  There are two types of treatment, In Vivo and Ex Vivo  Regardless of the type, each therapy requires a vector to transport DNA into cells

In Vivo Vs. Ex Vivo

Viral Vectors  Viral vectors are viruses that have had recombinant DNA inserted into their genome  They are injected into patients and infect cells allowing the new therapeutic gene to be copied  The addition of the “fixed” gene will begin to treat the genetic disorder

Non-Viral Vectors  Non-viral vectors are somewhat safer alternatives to viral vectors because they come without an infection risk  They involve different methods of delivery into cells Gold particles laced with DNA Electroporation: electrifying cell membranes to alter permeability Microbubbles and Ultrasounds

Non Viral Vectors (cont.)

Limitations  Still considered in trial phase  Viral Vectors can be infectious  Patient specific  Under developed technonlogy

Future  Higher success rates in patients  Transition to Non viral vectors Hydrodynamic Gene Transfer Jet Gun  Ability to cure and not just treat disorders  Ability to cure more diseases
