Stars show support for producer as his daughters battle rare disease

Stars including Julianne Moore and Channing Tatum have taken to social media to show their support for producer Gordon Gray, whose two young daughters are battling a rare brain disease.

Gray, the filmmaker behind sports movies such as Miracle, The Rookie and Million Dollar Arm, and his wife Kristen, recently launched the Charlotte + Gwyneth Gray Foundation in support of their daughters, four-year-old Charlotte and two-year-old Gwyneth, who are battling Batten disease.

The fatal neurodegenerative condition typically affects kids between the ages of six and 12. Symptoms of the disease include seizures, blindness, and loss of motor skills, and since Batten is so rare, there is little funding for research or clinical trials to find a cure or treatment.

Gray and his wife decided to take matters into their own hands and set up a foundation to raise funds and awareness for the disease, and Gray called upon his famous friends to get the word out about his new project.

The Grays created a video to tell their story with their daughters, in which Kristen says, "You're looking at your very healthy vibrant children, who are loving life right now, who could potentially lose all of that joy in a very short time. So we have a very short window to try and save them."

The video, along with a link to their foundation's website, has been reposted by celebrities including Moore, Tatum and his wife Jenna Dewan Tatum, Jennifer Garner, January Jones, Jessica Alba and Jessica Biel, among others.

Dwayne Johnson also took to his Facebook page to share the video, and added the caption, "I've never asked for donations, but this one's very close to my heart. Watch this video and if you can give $1 to the Charlotte & Gwyneth Gray Foundation - that would be amazing and mean the world to us. Thank y'all so much and maybe together, we can help cure Batten disease and save children's lives."
