Cameron Boyce died Saturday at the age of 20. The Disney Channel actor’s family confirmed that his cause of death was a seizure.

“It is with a profoundly heavy heart that we report that this morning we lost Cameron," a statement from a family spokesperson revealed to ABC News. "He passed away in his sleep due to a seizure which was a result of an ongoing medical condition for which he was being treated.”

The statement did not clarify exactly what type of medical condition caused the seizure.

Boyce had been working for more than half his life as an actor. He started working on screen in 2008, and he scored his first Disney Channel gig in 2011. He starred on the TV show “Jessie” for four seasons, and he also guest-starred on big Disney Channel shows like “Austin & Ally,” “Liv and Maddie” and “Shake It Up.”

The 20-year-old played a big role in the “Descendants” movie franchise. The TV films follow the kids of famous Disney villains. Boyce plays Carlos, the son of Cruella de Vil. He is set to appear in “Descendants 3,” which premieres Aug. 2.

“Descendants” trilogy director Kenny Ortega took to Instagram to write a tribute to Boyce.

The late actor and singer has several projects in post-production. “Paradise City,” a rock n’ roll TV series, is due out later this year, and “Runt,” an indie thriller about violent teens, is also finished filming. Additionally, Boyce is supposed to appear in HBO’s “Mrs. Fletcher,” which will premiere in the fall.

“The world is now undoubtedly without one of its brightest lights, but his spirit will live on through the kindness and compassion of all who knew and loved him,” the family’s statement reads. “We are utterly heartbroken and ask for privacy during this immensely difficult time as we grieve the loss of our precious son and brother.”
