Actress Jenny McCarthy was unable to attend Friday's autism conference in Pittsburg, Kansas as scheduled.
The Kansas Chapter of the National Autism Association reports on its website that her father unexpectedly fell ill. They say she plans to re-schedule her appearance.
Their website says the rest of the conference will go on as planned.
McCarthy has become active in autism awareness activities because she has a son with the disorder.
