The Grey’s Anatomy family has lost a member. Eric Dane, best known for playing Dr. Mark “McSteamy” Sloan on the medical drama, has died a year after he was diagnosed with ALS. He was 53 years old.
Dane’s family announced his death in a statement. “With heavy hearts, we share that Eric Dane passed on Thursday afternoon following a courageous battle with ALS,” the statement read. “He spent his final days surrounded by dear friends, his devoted wife, and his two beautiful daughters, Billie and Georgia, who were the center of his world. Throughout his journey with ALS, Eric became a passionate advocate for awareness and research, determined to make a difference for others facing the same fight. He will be deeply missed and lovingly remembered always. Eric adored his fans and is forever grateful for the outpouring of love and support he’s received. The family has asked for privacy as they navigate this impossible time.”
Dane is survived by his wife, Rebecca Gayheart, as well as their two children, Billie Beatrice Dane and Georgia Geraldine Dane.
What was Eric Dane’s cause of death?
According to Dane’s death certificate, Dane died of respiratory failure. Amyotrophic lateral sclerosis (ALS) is an underlying cause of death.
In their statement announcing his death, Dane’s family confirmed his passing was related to his diagnosis with ALS, which he announced he was diagnosed with in April 2025. “I have been diagnosed with ALS,” he told People at the time. “I am grateful to have my loving family by my side as we navigate this next chapter.” He continued, “I feel fortunate that I am able to continue working and am looking forward to returning to set of Euphoria next week. I kindly ask that you give my family and I privacy during this time.”
According to the Mayo Clinic, ALS is a nervous system disease that affects nerve cells in the brain and spinal cord, which causes the loss of muscle control. The disease, which gets worse over time, starts with muscle twitching, slurred speech, or weakness in an arm or leg. ALS, which gets worse over time and has no cure, affects the control of muscles needed to move, speak, eat, and breathe. The disease is also often called Lou Gehrig’s disease after the baseball player who was first diagnosed with it in the 1940s.
While the exact cause of the disease isn’t known, the Mayo Clinic reported that for about 10 percent of people with ALS, a risk gene—also known as hereditary ALS—was passed down by a family member. In most people with hereditary ALS, their children have a 50 percent chance of inheriting the gene.
ALS is also most common between the ages of 60 and mid-80s. It’s also slightly more common in women than men before the age of 65. This sex difference disappears after the age of 70.
What was Eric Dane’s health like before his death?
At his last public appearance before his death, Dane called his ALS diagnosis “so horrible.” “I have no reason to be in a good spirit at any time, on any given day, I don’t think anybody would blame me if I went upstairs in my bedroom, crawled under the sheets, and spent the next two weeks crying,” he said at a virtual panel for Giving Tuesday in December 2025. “And I was a little bit pleasantly surprised when I realized that I wasn’t built like that, because I thought for sure that was gonna be me.”
He continued, “I make sure that people are aware of what ALS is and what it’s about, and more importantly, what we can do to combat it and improve the landscape, because it’s so rocky and littered with hurdles and bureaucracy and all this other nonsense that we’re trying to sift through so we can get to a place where we go, start working on solution.” He also added that it felt “very encouraging” that he could appear on the panel and have a “buoyant spirit in the face of something so horrible.”
