'Stranger Things' Star Gaten Matarazzo On His Rare Disorder: 'I Want To Raise Awareness'

"A lot of people have it much worse than I do."

The young actors from Netflix's "Stranger Things" continue to impress.

Gaten Matarazzo, who plays Dustin on the series, recently appeared with his co-stars Caleb McLaughlin and Millie Bobby Brown on The Jonathan Ross Show in the U.K. During the interview, Matarazzo opened up about living with a rare genetic disorder called cleidocranial dysplasia.

"It's a condition where you're born without your collarbones," Matarazzo explained. "I don't have any. It affects your facial growth, your skull growth, it affects your teeth. I don't have any. These are fake right here. I have teeth, but they're all baby teeth."

Matarazzo went on to say that he needs "a lot of surgery," but added, "I have a really mild case, and a lot of people have it much worse than I do."

You might remember Matarazzo's Stranger Things character mentioning cleidocranial dysplasia after being bullied about his teeth. That's because his real condition was written into the series. "I feel like putting it into the show has really raised awareness for it," he said.

He also explained that, although the condition "usually is passed down through genes, it wasn't for me. It just happened." He says he now has a 50 percent chance of passing it down.

Matarazzo wants to "let people know it's not something they should be afraid of showing."

It's not the only way the young actor is spreading positivity through his newfound fame. Last month he shared several selfies he took with fans on Instagram, because "they mean as much to me as I mean to them."
