The case of donor 7069
In June, I was invited to speak at an event organised by Progress Educational Trust (PET) titled ‘Donor Conception and Genetic Disease: Lessons to Be Learned from Donor 7069′.
This was a discussion about the case of a sperm donor where it was discovered that he (unknowingly) carried a genetic mutation that causes cancer. Over the years, his sperm had been used to conceive at least 197 children in at least 14 countries. Some of the children have developed cancer and, tragically, some of those have died.
The case raised important questions around how genetic testing works and what it can pick up, family limits and how many children should be conceived from one donor and the procedures that are in place to allow a donor’s medical information to be updated and shared. These were the areas that the PET event was aiming to address and DCN was on the panel to try to draw out the implications for donor conception families and how they might respond to the case and the issues it raised.
I’m not going summarise the presentations here but do check out the recordings on the PET website. Instead, I want to highlight something that for me seems to be an issue that lies at the heart of the conversation.
To start off, the good news was that this was not a story about a known risk being ignored or a donor who should never have been accepted. The genetic mutation couldn’t have been tested for, so it couldn’t have been picked up. That is small consolation to the families affected, of course, but important to remember.
But one thing the case brought to light was how prospective parents considering donor conception can feel a huge weight of responsibility on behalf of their child in getting their choice of donor ‘right’. It means that any subsequent problem that might, even tangentially, be associated with that donor can take on more significance. There can be a sense they should or could have done something to avoid the issue and if it’s something health related that can feel particularly devastating.
It’s important to remember that genetics don’t determine everything health-wise and actually, perhaps don’t determine that much. Genetic screening can reduce risk, but it cannot remove it entirely and there is a huge amount we don’t know about genetic inheritance and how it plays out in health and disease. But parents still want to feel like they’ve done their best to make good decisions on behalf of their child.
For donor conception families the lack of medical information about the donor is a point of real frustration more generally. This case demonstrates an extreme example of that. But actually, questions around medical history and the current health of your close genetic relatives is something most people consider hugely important in managing their own health decisions and those of their children. And of course, those health issues can arise in different ways and at different points throughout life.
Other cases have also drawn attention to this kind of issue. A new law was passed in Australia in 2016, informally referred to as Narelle’s law. It was named after Narelle Grech, a donor conceived woman who spent 15 years searching for her biological father. Shortly after finding him, she died of heritable bowel cancer which was one reason she was so determined to trace him. Her case led to the law changing and retrospectively cancelling the guarantee of anonymity that donors were given in the early days. This was in in part in recognition of the importance of being able to ask questions about medical history, something she really needed.
These extreme cases keep reminding us about the importance of health records and the implications for donor conception families where the information is not available.
In other families, health information can be updated informally via conversations discussing uncle John’s newly discovered diabetes or Grandad’s dementia diagnosis. If a question needs answering, normally there will be family members available to ask and people may take for granted the fact that they can access those facts. That’s not the case for donor conception families.
And there are so many situations now where people are asked for their family medical history, from pregnancy, to registering with a GP, to getting an eye test. Not having that information can feel like a serious gap, particularly if there are current health issues and people want to understand if there might be a genetic component and how it might affect them or their children.
For donor conception families, even if they have some information, they are working on trust that it was shared and recorded fully and accurately in the first place. They have no idea if the donor’s health profile has changed since they donated. Do they now suffer from a late-onset autoimmune condition or did their father go on to develop Parkinson’s?
And if a child or donor conceived adult develops a condition where they suspect a genetic component may be part of the picture, they are unable to join things together to get clarity. Do they need to let the clinic know? Are other children affected? Should the donor be informed?
Currently, there is no standard model for donors to update their details and no model for parents or donor conceived people to follow if health issues arise and they want to feed that information back into the system to be shared. Some clinics have their own systems and procedures, which is good. But it’s patchy and inconsistent. And it’s hard or impossible to back-date the process to include former donors.
Of course, creating this kind of complex communication and reporting system isn’t easy to set up, run and monitor. And it’s expensive, which will only increase costs.
The solution isn’t straightforward. But perhaps as a minimum, the case of donor 7069 should remind us that these issues can affect people in the most significant ways and we need a bigger discussion on exactly what’s needed and where responsibilities lie.
Let’s at least start having that conversation.
