Confined placental mosaicism

Currently going through hell and wondered if anyone has experienced something similar to me with a positive outcome.

- We have had high risk harmony (due to high hCG and low PAPP-A)
- Slow increase NT highest being 3.2
- CVS test showing 60% Mosaic Downs in the placenta
- In the wait (3 weeks) for amino
- Baby heart has been checked and is almost perfect
- Baby has a nasal bone

Has anyone been through similar and got the result of Confined placental mosaicism?

Thanks in advance for any advice

In my case I did have a diagnosis of Confined Placental Mosaicism briefly - then specialist opinion leaned towards low level mosaicism. We had tests and investigations for about 5 months of the pregnancy 🤰 x

Really hope you’re ok x

Hi @Trying2stayhopefull not to promote another forum but I did find the babycentre antenatal scans and tests support group helpful when I was in turmoil in my pregnancy. The search function was really helpful in being able to find people who had been in a similar position to me (not confined placental mosaicism in my case but I’m sure you’ll find some results) Sending you love at this most difficult time xxx

My NT measurement was also 3.2 x

@Sixtyorforty oh sorry to hear. When did you get the measurement? How was everything else. It could all be ok.

The measurement was at around 13 weeks. My downs risk was 1 in 166. Baby was born completely healthy x

@Trying2stayhopefull no experience as ours was not mosaic but a full copy, I just didn't want to read and run. The wait for results is the worst and I really hope the weeks pass quickly for you and that you'll get the confined result. 🤞🏼

@NoCallerID oh so sorry to here that. Was that a CVS or Amnio? I hope that you are ok x

@Trying2stayhopefull thank you, we decided to TFMR, there were physical issues too. It's been over a year and we've had further heartbreak since but are now expecting again (very early still). It was the CVS. But we had been told if it came back mosaic we'd need the Amnio. Has anyone pointed you towards the ARC? They're really helpful and a really good ear to listen to. X

@NoCallerID I’m unsure if ARC has improved, however my experience was that they had little understanding of mosaic results when I sought support around my situation. It may have been a one off however.

@SarahD19 I have no experience with mosaic myself but found the ARC helpful. Not only to talk through results or anything but simply an ear listen to. I don't think anyone would expect them to know more than doctors and consultants tell parents?

@NoCallerID thank you for sharing your story with me. I wish you all the best with your pregnancy. Xx

@NoCallerID I am really glad you found the support helpful. As I say, not meaning any criticism but my expectation was that ARC was a service to support parents to be in making informed choices around prenatal tests - so expected a sound knowledge around mosaicism. This may or not be realistic...

My experience was a lot of emotional labour went into having to explain the mixed test results I got to so many people - at a time when I was experiencing profound confusion and disbelief about those tests myself. I got so tired of having to explain it all to everyone, including the majority of professionals who were in supportive roles around me. This added another layer to the stress of the experience in many respects.

I really hope you’re well and wishing you good outcomes moving forward x
