Condolences go out to Regis Philbin, who is mourning the death of his 49-year old son Danny Philbin.

Danny Philbin was born with a defect in his spinal cord that required both his legs to be amputated. Despite his physical challenges, however, Philbin embarked on a successful career with the U.S. government, working for the Department of Defense’s Public Affairs Office.

Philbin passed away from natural causes in November, reports The National Enquirer, but his death wasn’t publicized until now.
