Indeterminate micro deletion

Just got my NIPT results Back. Chromosome 15 is showing indeterminate micro deletion. We have an appointment with the genetic counselor but I was hoping somebody could share more info. They made it seem that it could just be an issue with the blood test but reading into it. I also know there could be larger problems. We will likely have to go for an amnio, but that won’t be for another three weeks. Any stories of people who had indeterminate micro deletions on there and It turned out to be fine thank you.

Re: Indeterminate micro deletion

  • @knottiec21bd39fb39f7301 I'm honesty surprised your NIPT tested for microdeletions.  Our MFM said they typically don't test for all the micro deletions because there are just way too many to test for.  I would say wait until the amnio to really start looking into it because worrying now won't change anything.  I know that is much easier said than done.  I'm sorry you are going through this.

  • Just adding my research input her: I came across this article, and it looks like the NIPT might be able to predict the presence of Chrom 15 microdeletions exclusively. 

    Something to remember is that NIPT is a screening  tool, not a diagnostic tool, so you might not need to be worried about it at all. As @scaredunprepared said, recommend waiting until after the amnio. Of course, I can say "don't worry" but that's not going to happen, right? So... try not to worry too much at this point.
