Ryan Dant graduated from the University of Louisville on Saturday. His father credits "hard work and great science" for even making the day possible. Click through our gallery to learn more about Ryan's life.

Ryan was born April 13, 1988, to Mark and Jeanne Dant.

Ryan appeared to be a healthy boy at age 2. His growth was normal in his first couple years, his body coordination was on par, and his vocabulary was expanding just like that of most children his age.

He was diagnosed at age 3 with MPS, a deadly disease that leads to stunted growth, heart disease and mental deterioration.

Ryan was a fan of the University of Louisville Cardinals from an early age.

Ryan Dant was the focal point of several fundraising efforts, including golf tournaments, arranged by his father for MPS research.

In 1998, shortly before his 10th birthday, Ryan Dant headed to UCLA to join a group of 10 children participating in clinical trials for an experimental MPS treatment. The treatment extended his life but didn't stop the dangerous deterioration of his brain.

The fundraisers continued throughout Ryan's teen years.

Ryan helps lead Hebron High School's football team to the field during its 2006 run to the Texas state championship. The coaches let Ryan play one snap his senior year.

Dr. Elizabeth Maher, of UT Southwestern Medical Center in Dallas, agreed to admit Ryan in a compassionate-use trial to test whether a spinal injection of special enzymes could stop his cognitive decline.
