The Stop Sign in Aidan’s Genes (PURA GENE)

I have something special to show you, a little piece of yourself.

But first let me tell you why it’s so incredible to me.

My son Aidan was born 13 years ago with an undiagnosed developmental disability so for 13 years I’ve been watching human development in slow motion. The strength of our muscles, the authority of the brain, the power of the body to heal. The same brain that’s made it difficult for him to walk and impossible for him to speak, has also given him the cognitive ability and dexterity to drive a power wheelchair and find other ways to communicate.

For 13 years Aidan’s medical team has been searching for a cause of his medical issues. For 13 years we’ve come up empty handed.

Until now.

Six months ago Aidan’s whole exome was sequenced and we found two genetic mutations.

Allow me to show you your PURA gene:


Each of those letters represents one of the 322 amino acids on your PURA gene. You had no idea how complex and amazing you are, did you? This is a very specific code of instructions. I can’t comment much on the science partially because it’s all still confusing to me and also because the PURA gene has not been studied enough in humans.

Now let me show you Aidan’s PURA gene:


Where you have an N Aidan has an S. These both have similar functions and so this variation may or may not be a problem. However, where you have a K, Aidan has an X. Look what happens after the X. Nothing. X is a genetic stop sign. Aidan has incomplete instructions and that is definitely a problem.

These are de novo mutations in Aidan, more specifically, he did not inherit them from his dad or me. Many of us have changes in our genes that are of no particular consequence.  But sometimes it’s life altering.

As genetic testing becomes more affordable and readily available, we will be learning more about previously undiagnosed children. This conversation is going to become more commonplace. We will all need to work together to understand what we learn. While there is enough information about the PURA gene to believe that it’s causative in nature to Aidan’s medical issues, there is not enough information to give Aidan an actual diagnosis.

There is work to be done. Research. Studies. People looking into microscopes, gathering information, and writing long, in depth papers.

This is why their works matters to me:

I am 13 years into this journey and no longer in trauma mode. I have the endurance to fight Aidan’s medical battles and the privilege of celebrating his achievements.

But there is some mom in a NICU somewhere whose child has a genetic variance that could be causing problems. This is my moment to help her, my chance to reach back in time a little and remind myself that I’ve never really been alone.

I hope that you will join me.


Here’s how you can help:

1. Share this post. If you doubt the power of social media, read the article, “Hunting Down My Son’s Killer” which brought families and researchers together and eventually led to the formation of the Grace Wilsey Foundation which is committed to fighting this particular disease. Their journey is chronicalled in this New Yorker article. So please, share.

2. If your child has a genetic mutation on his/her PURA gene, I would very much love to hear from you.

3. If you’re a scientist who would like to suggest reading for me or any other information, I would greatly appreciate that as well.

For another great read from a parent with a stronger science background, check out Dana’s post here.

Take all of the scientific information with a grain of salt as I’ll take metaphors and colorful words over codes and patterns any day. And thank-you to the REAL Dr. Bowie for ongoing   help. (Yes, longtime readers, their are two real Dr. Bowies in the family and neither one of them is me.)

  1. Heather, this is exciting news even if it isn’t immediately helpful. I promise to pass this along as I know many parents whose children have various development issues. I will also be going back and reading all your writings when I can.
    Aidan has your family’s smile, which I love so much. It is so joyous!

  2. Thanks Heather for explaining this so well. I am glad you have some answers to some if the questions and well done for being so persistent and enquiring, it will always stand you in good stead. Love to you all and look forward to our autumn meet up! I love the picture and hope Aidan is mobilising well.

  3. Dear Heather, I’ve been keeping up with you through Jessica, and I am so grateful to Jen for posting this on Face Book. You have always been special and strong, and I hear it in your writing — some of your mother’s genes, perhaps? Be assured of my continuing prayers for all of you — Love, Ede-Jo

  4. I’m glad you’ve gotten some answers about your beautiful boy and I know that more and more answers will be available to that scared mom in the NICU because of what you’re doing. I look forward to hearing what all of this means for the next steps!

  6. This is a cause special to my heart as well. My daughter Brooke has Aicardi Syndrome but there is no known cause. So much research is going on to try and find out the genetics behind it. Hugs and prayers!

  7. I enjoyed reading your post about when Aidan was born and these posts about his genetic makeup. It’s a new real side to him and good for us who are with him all day to know about.
