Disney Channel star Cameron Boyce has passed away at the age of 20.

The young actor's family confirmed the news of his death in a statement to E! News Sunday morning, which read: "It is with a profoundly heavy heart that we report that this morning we lost Cameron. 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."

Boyce was perhaps best known for his work as Carlos on the Disney Channel's Descendants films and Descendants: Wicked World TV series and had completed work on the upcoming sequel Descendants 3 prior to his passing. He also starred as Luke Ross on Disney's family comedy series Jessie.

Disney Channel issued the following statement after Boyce's passing: "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," a Disney Channel spokesperson said. "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."

His Jessie co-star Skai Jackson responded to the tragic news by writing, "I never thought in a million years I would be writing this. Cam, you were one of a kind. My heart will be forever broken. 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."

Peyton List also paid tribute to the actor on her Instagram page by writing, "Cameron, I love you with everyone ounce of me, and I thank you for the time I had with you, being in my life, and being my brother forever and always."
