PHOENIX -- Isaiah Acosta is a 17-year-old from Phoenix who was born without pathways for oxygen to enter his body.
He also was born without a jaw, has never tasted food and is mute, but communicates through sign language, gestures and primarily texting on his phone.
"He's not scared to be rejected," his mother, Tarah, says, in a video featuring her son. He has been offered a cosmetic jaw and turned it down, she said.
Isaiah also loves hip-hop, writes raps and dreams of being a rapper.
A Phoenix rapper helped make that dream come true as part of a short documentary on Acosta that started going viral immediately after it was released Thursday morning.
