Mitte, who played Walter "Flynn" White, was diagnosed with cerebral palsy at age 3 and has since brought awareness to the illness as the official ambassador for United Cerebral Palsy Foundation and Shriners Childrens Hospitals, his publicist said in a news release.
His character on AMC's hit show also had cerebral palsy, which is a neurological disorder that affects body movement and muscle coordination, the National Institute of Health says.
He was given a negative prognosis by his doctors, saying he'd never be able to walk properly, ABC 6 reports. Although Mitte's character had to use braces to walk, he hasn't let cerebral palsy limit his mobility.
On Saturday, he shared his story of how Shriners helped him with his cerebral palsy treatment.
"I guarantee you I wouldn't be who I am today or have the abilities that I have today without Shriners," said Mitte, ABC 6 notes.
“They do so much amazing work, not just for disabilities but for burns and a spectrum of disabilities. And it’s always such an amazing honor to be able to come out and be a part of these events. And to be able to show my support,” Mitte told WCCO.
More than 500 walkers, many of them who suffer from cerebral palsy and were told they'd never walk again, participated in the first-ever Walk for Love, which raises money to benefit the patients of Shriners hospitals, according to Shriners' Facebook page.
The event raised over $56,000 for Shriners, WCCO says.
While in Minnesota, Mitte also attended a Twins game, played Legos with kids at Shriners Twin Cities and met with other Shriners patients.
