PHILADELPHIA (KYW Newsradio) — There's a side to the late Philadelphia-born actor and comedian Bob Saget that most people may not know.
He was an advocate for fundraising for research into scleroderma, the autoimmune disease that killed his sister Gay in 1994.
Saget raised more than $26 million for the Scleroderma Research Foundation.
Back in December, Saget talked to CBS News Chief Medical Correspondent Dr. Jon LaPook about keeping his sister's memory alive.
"I can't watch what happened to my sister happened to more people if I can do anything," he said.
"Raising awareness is one of the things that get you there. And for me, it's an homage to her and somehow telling her that her life had a real purpose."
In the years since Gay Saget's death, doctors have learned much more about scleroderma. It can now be treated with medication if it's caught early.
