"EXTREME MAKEOVER: HOME EDITION" MENDS THE HOME OF TWO ILL DAUGHTERS WHO MUST LIVE IN A STERILE BUBBLE TO SURVIVE

"Extreme Makeover: Home Edition" continues its mission to honor special everyday heroes and heads to Las Vegas, NV to tell the Cerda family that their unfit home, which is threatening the lives of their two daughters who have an immune disorder, will be rebuilt in seven days. "Extreme Makeover: Home Edition" airs SUNDAY, MAY 10 (8:00-9:00 p.m., ET) on the ABC Television Network.

Terri and Chuck Cerda's two daughters, Molly and Maggie, were diagnosed with Combined Immune Deficiency Disease (CIDD) at the age of three and are now living in a home that is threatening their lives. CIDD -- a disorder of the immune system similar to that suffered by David Vetter, the "boy in the bubble" -- means that a simple cold is a life threatening lung infection. Chuck Cerda works as a Homeland Security police officer, and his wife, Terri, has worked all her life in global relief, organizing search & rescue dog services during disasters such as the Mexico City earthquakes and the Colombia mudslides. She's also worked as a volunteer for a number of community organizations, including the fire department and ambulance service. Terri has used her experience as an advocate and mother of two ill children to found Artful Hearts, which gives painting murals to organizations, clinics and foundations that operate to support other children fighting life threatening medical conditions. She also works as a patient advocate for the Immune Deficiency Foundation, a position which has taken her to Washington, DC to meet with senators to influence laws governing medications that could save thousands of lives.

In 2004 the Cerdas were fraudulently sold a home that was in poor condition while their oldest daughter lay in intensive care. After six floods, they were forced to make repairs themselves, but after a recent inspection, structural engineers advised them to gut the house or tear it down and rebuild. The water damage is extensive and sewage continues to back up into the home. A load bearing beam is also threatening the structural integrity of the house.

While Ty and the designers, local builder Wright Custom Home and hundreds of volunteers and workers are rebuilding their home, the Cerda family will go on vacation to Maui, Hawaii.

The design team for this episode of "Extreme Makeover: Home Edition" will feature team leader Ty Pennington and designers Paul DiMeo, Eduardo Xol and Didiayer. The series is produced by Endemol USA, a division of Endemol Holding. It's executive-produced by Anthony Dominici. David Goldberg is Chairman, Endemol North America. "Extreme Makeover: Home Edition" is broadcast with Spanish subtitles via secondary closed captioning. This program carries a TV-PG parental guideline.
