“Jim was champion for so many small charities and causes in NI and that legacy will live on. Condolences to family and friends at this sad time.”
Dornan had been diagnosed with lymphocytic leukaemia in 2005 and had worked closely with the charity ever since.
Dornan was a world-renowned obstetrician and gynaecologist. He was also a professor of Foetal Medicine at Queen’s University Belfast from 1995 to 2012 and senior vice-president of the Royal College of Gynaecologists from 2004 to 2006.
He also had a guest role in his son’s gripping BBC One series The Fall, where he played a member of the police board called John Porter in one episode.
Dornan is survived by his second wife, Samina, and three children by his late first wife – Liesa, Jessica, and Jamie. The Fifty Shades of Grey star, 38, is yet to comment on the news, but his representatives have been approached for comment.
A number of his former colleagues paid tribute to the doctor following the news.
Nichola Rooney, Chair of Division of Clinical Psychology NI, tweeted in tribute: “The great Prof Jim Dornan. One of a kind. His glass brimmed over.”
BBC NI Health Correspondent Marie-Louise Connolly tweeted: “It is with much sadness that I am writing that Professor Jim Dornan has died.
“Hard to accept that someone with so much life, wit, and full of advice and laughter has left this world.
“A true friend. Thoughts are with his family and medical friends around the world. RIP Jim.”
Dornan’s first wife Lorna – Jamie’s mother – died in 1998 after being diagnosed with stage four pancreatic cancer.
Jamie, who was just 16 when his mother died, previously spoke about the devastating time his father told him about the “fatal verdict.”
He told The Times in 2019: “I burst into tears immediately. I was so angry and confused, my mind was swirling.
“I still hoped they’d come up with a cure in the time Mum had left. My grief started before Mum was dead.
“Grief hit me in waves in the years after, when the weirdest thing would set it off.”
