Upshot - woman is suing NHS as they didn't inform her about her father's Huntingdon's diagnosis. (an incurable inherited degenerative condition hitting in mid life characterised as being like Parkinson's, Alzheimer's and MND all rolled into one)
He had shot and killed her mother in 2007, and was convicted of manslaughter on diminished responsibility due to his mental health issues - which were confirmed as Huntingdon's shortly afterwards.
On finding this out, and in spite of the NHS providing family therapy for them both together, ostensibly for both of their benefit, his wish for the, at the time, pregnant daughter not to be informed as she might have "killed herself or had an abortion" was enough for her not to be told of his diagnosis. She found out by mistake shortly after the child was born, got tested, and it turns out she has it too - her daughter has a 50% chance of also having the disease.
I know patient confidentiality is a somewhat grey area in the UK, even if any diagnosed medical issues are potentially damaging to other individuals.
This strikes me as a somewhat feminist issue - although she was always going to develop the disease whether she had been told or not, she has potentially made her child into her carer. She also maintains she would have aborted the baby rather than have subjected her to this horrific disease.
Personally, I hope she wins her case. I am a carrier of Cystic Fibrosis and am lucky that my father told me about his late brother and advised me to get tested before having children, so am very sympathetic.
