Disney star Cameron Boyce has died at age 20.

According to ABC News, which is part of the Disney/ABC Television Group owned by the Walt Disney Company, Boyce died Saturday from a seizure due to an ongoing medical condition. The Disney Channel confirmed his death to USA TODAY on Sunday morning.

Boyce was known for his roles on the Disney Channel’s “Jessie,” in which he played one of four wealthy, rambunctious children under the care of a new nanny, and the ”Descendants” franchise, as the son of Cruella De Vil.

”It is with a profoundly heavy heart that we report that this morning we lost Cameron,” the family told ABC. ”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 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. We are utterly heartbroken and ask for privacy during this immensely difficult time as we grieve the loss of our precious son and brother.”

Born May 28, 1999, Boyce’s first acting credit was in a Panic! At the Disco music video at age 9, according to IMDb. He made guest appearances in a handful of Disney Channel shows, including “Good Luck Charlie,” “Shake It Up,” “Austin and Ally” and “Liv and Maddie.”

Boyce starred in “Jessie” from 2011 to 2015 as Luke Ross, the mischievous second oldest sibling, and voiced the titular role in “Jake and the Neverland Pirates,” an animated Disney Junior show that ran from 2012 to 2015.

His role as Carlos in the “Descendants” franchise has spanned multiple movies, shorts and a TV spinoff since 2015. ”Descendants 3” is scheduled to premiere on the Disney Channel on Aug. 2.

”From a young age, Cameron Boyce dreamed of sharing his extraordinary artistic talents with the world. As a young man, he was fueled by a strong desire to make a difference in peoples’ lives through his humanitarian work,” the Disney Channel told USA TODAY in a statement.

”He was an incredibly talented performer, a remarkably caring and thoughtful person and, above all else, he was a loving and dedicated son, brother, grandson and friend. We offer our deepest condolences to his family, castmates and colleagues and join his many millions of fans in grieving his untimely passing. He will be dearly missed.”

Disney CEO Robert Iger tweeted condolences on behalf of the company:

Several of Boyce’s co-stars and colleagues responded to the news Sunday on social media.

Skai Jackson, who played Boyce’s younger sister on “Jessie,” shared photos of the two through the years.

”I never thought in a million years I would be writing this,” she posted on Instagram. “I am so happy that I got to spend almost everyday with you on set, you gave the best hugs. I wish I would have hugged you tighter when I saw you a couple of months ago. Thank you so much for being the big brother I never had.”

“Descendants” director Kenny Ortega shared a photo of Boyce on the set. “You will forever live in our hearts,” he wrote.

Kristin Chenoweth, who played Maleficent in the first “Descendants” TV movie, commented on Ortega’s post that she was “devastated.”

Adam Sandler, who played Boyce’s father in the 2010 comedy “Grown Ups,” shared a close-up photo of Boyce along with a written tribute.

”Too young. Too sweet. Too funny. Just the nicest, most talented, and most decent kid around,” Sandler wrote. “Loved that kid.”

“Wizards of Waverly Place” alum Gregg Sulkin tweeted that he was “heartbroken” and “lost for words.”

”I had known Cameron Boyce for many years. He was always polite. Always respectful and always a class act. In fact, I was going to message him a couple weeks ago to tell him that I wanted to be in each other’s lives more. Now I wish I had sent that message,” he wrote. “Cameron, you were and still are a star.”
