A Charleston organization wants to shine a light on autism.

Autism Speaks said autism is one of the fastest growing disabilities in America, with one in 88 children affected.

To celebrate World Autism Awareness Day on Tuesday, Charleston-based Childhood Language Center hosted its "Light it up Blue" open house. Dozens of community members came out to show their support and learn more about autism, while enjoying lunch and blue velvet cupcakes donated by Lil' Bit of Heaven Cupcakes.
