Receiving a negative pre-symptomatic genetic test result

This section is about receiving a negative pre-symptomatic genetic test result for a genetic variant linked to inherited MND. It covers:

  • Being given the news
  • Initial reactions to receiving a negative result
  • Adjusting to knowledge of a negative result
  • Attitudes to life, plans and decisions
  • Reflecting on the decision to have pre-symptomatic genetic testing
  • MND as an ongoing presence

Four of the people we interviewed had found out that they do not carry the particular genetic variant of inherited MND that was identified in their affected relative. Maggie, Kelly and Georgia Z had a pre-symptomatic genetic test themselves, and Kirsty found out she did not carry the C9orf72 gene variant through her mum, Maggie’s, negative result. We talked to these individuals about what it was like to find out that they had not inherited the gene variant linked to inherited MND identified in their family.

Being given the news

Maggie, Kelly and Georgia Z all went through pre-symptomatic genetic testing in 2020, during the Covid-19 pandemic, yet they had different experiences of receiving their results. Maggie’s counsellor asked her whether she wanted to receive her results over the phone or by letter. She asked to be called on her landline so she would be at home when the call came. Whilst she valued being in her own environment, she felt that having a video appointment would have been better.

Georgia Z asked to receive her genetic testing results over the phone. Having an appointment with face masks and social distancing was not the experience she wanted.

Kelly and her counsellor chose to have a face-to-face appointment. They decided that only Kelly and her husband would be present, which Kelly felt was the right decision so she would not be worried about her mum’s reaction.

Initial reactions to receiving a negative result

For the people we spoke to, being told they did not carry the particular genetic variant of inherited MND identified in their family was both a shock and a huge relief.

On finding out that her mum did not carry the C9orf72 gene variant, Kirsty felt shock and disbelief. She was grateful that her mum and immediate family had “been spared”.

Kelly describes the appointment where she received her pre-symptomatic genetic test results. Being given a negative result was “the most amazing news”, and she felt a weight lifted from her.

Maggie, Kirsty and Kelly had all expected bad news. Kelly described how “I’d kind of prepared for the worst because it’s easier to deal with in thinking it’s going to be the worst case scenario; anything else is a bonus”.

Knowing that three of her siblings carried the C9orf72 genetic variant, Maggie did not allow herself to imagine that she could test negative.

For those with children, receiving a negative result has wider implications for them too. Where a parent tests negative for the genetic variant in the family, their children are no longer at risk of having inherited this particular gene variant. For Kirsty, this meant that she did not have to consider having pre-symptomatic genetic testing herself.

Maggie had thought a lot about how to discuss a positive result with her daughters and granddaughter. She felt relieved that these conversations would not have to happen.

Adjusting to knowledge of a negative result

For some of the people we interviewed, being told they had not inherited the particular gene variant identified in their family was an adjustment to the future they had imagined.

Maggie had started to worry about being a “burden” on her family. Knowing she hasn’t inherited the C9orf72 gene variant has made her feel like she can go back to being herself again.

Georgia Z feels reassured to know that she hasn’t inherited the C9orf72 gene variant, but knowing that other relatives could develop symptoms makes this “bittersweet”.

Georgia Z raised how some people struggled with knowing that other family members could be affected by MND. Kelly also has a close relationship with her cousin who received a positive pre-symptomatic genetic test result. Georgia Z and Kelly found sharing their results difficult, though both said their relatives were happy for them and supportive. Maggie was told by her counsellor that how she felt about her results could change, but she doesn’t feel it did. She hasn’t struggled with feelings of guilt as her counsellor said some people might.

Although some people found they were able to process the results and move forwards, others found it took some time to adjust to the news of a negative result.

Although she had prepared herself for bad news, once Maggie was given her pre-symptomatic genetic test result, she found she didn’t really need time to process it.

Kirsty struggled with knowing what to do with the fears and emotions that had accompanied her since finding out about the family history of MND. There was a feeling of “Now what?”

Kirsty valued the interview as an opportunity to discuss her experiences. Through her testing process, Kelly has learnt that “talking is good”. Following her result, she appreciates being able to talk openly with her mum and cousin.

Attitudes to life, plans and decisions

Receiving a negative result can see a shift in perspectives and attitudes to life. Some people we spoke to had a sense of being “lucky”. Kirsty described how “you sort of feel like you’ve just escaped something, like there was a close call”.

Going through genetic testing has changed Kelly’s outlook on a lot of things. She has a new appreciation for her health and has given up smoking.

Whilst Kelly’s focus has been on looking after her body, Maggie has found she is no longer as alert to bodily sensations or possible symptoms, which before her test was something that worried her. Maggie described how “the horizons have opened up a bit more”. She felt pleased that she could continue to enjoy everyday life with her family.

Other people we spoke to also talked about how knowing they do not carry the C9orf72 gene variant impacted their views on and plans for the future. For Kelly and Georgia Z, knowing they wanted to have children was a factor in their decisions to have genetic testing in the first place.

Kelly feels lucky to be able to move towards the future she had hoped for, in terms of planning for a family and other goals such as buying a house.

Kirsty also felt grateful that she wouldn’t have to consider inherited MND when making decisions around having a family.

Kirsty feels grateful that she will be able to focus on starting a family when it is right for her and won’t be faced with difficult decisions around genetic testing before or during pregnancy.

Georgia Z said, “I just know that I can kind of live life to the fullest, I don’t have to worry”.

Reflecting on the decision to have pre-symptomatic genetic testing

Maggie, Kelly and Georgia Z remained pleased with the decisions they had made around genetic testing. Maggie felt the timing had been right for her, as she “wasn’t ready” to do it sooner. Kelly also felt that waiting was the right thing to do.

When Kelly initially considered genetic testing, “it was for the wrong reasons”. She feels that waiting to have the test was right for her, as she was clear on why she was doing it.

MND as an ongoing presence

Although the people we spoke to felt relieved and grateful that they themselves had not inherited the gene variant linked to inherited MND identified in their family, they highlighted that MND would continue to be a part of their lives. Some had lost relatives to inherited MND, had relatives currently affected, or were worried about the possibility that other family members could develop the disease in the future.

For some of these individuals, it was important to use their experiences to help others. This included through fundraising or raising awareness on MND and supporting other relatives who had an increased risk of developing the condition. Kelly and Maggie have volunteered to take part in research as control samples for family members.

Maggie looked forward to being able to get together with family to mark the significant events that had happened since the start of the Covid-19 pandemic, including celebrating the life of her brother, John.
