Chromosome 3 Deletion Syndrome

Posted by mcconnector @mcconnector, Jan 4, 2020

Does anyone have experience with, or know about, Chromosome 3 Deletion Syndrome? Thank you.

Interested in more discussions like this? Go to the About Kids & Teens Support Group.

Hi @mcconnector, welcome to Connect. I'm bringing @aworriedmom @jennsprung and @5qdeletion into this discussion. They too are familiar with chromosomal deletion, however not necessarily chromosome 3 (

From what I understand the mental development and physical signs and symptoms of 3p deletion syndrome vary greatly. How old is your child? What challenges are you facing?


Hello, Colleen and others.

Thanks for replying.

Our child is 15, and the challenges are many. Some of the "usual symptoms" (for example, "autism spectrum" and behavioral problems) seem to be in our picture, but others (for example, some of the physical symptoms) don't seem to be.

We seek fourfold advice (and whatever other advice you might offer us): medical, educational, behavioral, and residential:
1. Is there a clinic, or are there doctors, who are "go-to" experts on treatment of Chromosome 3 Deletion Syndrome?
2. Are there schools that you would recommend for teens with Chromosome 3 deletion?
3. Are there behavioral therapists whom you would recommend for a teen with this condition?
4. Are there foster homes (group homes) or other residential options that you would recommend?

Thank you for whatever advice and recommendations you might have for us.


@mcconnector, with rare diseases, I often first turn to NORD (National Organization for Rare Disorders) to find experts and researchers. See this page

Since your son's Chromosome 3 Deletion Syndrome has similarities with behaviors on the autism spectrum, I've also added this discussion to our Autism (ASD) group

You ask excellent questions. I'm confident that @mamacita and others like @cindyhanauer will have some thoughts for you. I will continue to help find other parents with children with 3p deletion. mcconnector, it might help to know what state or country you live in.


Thank you, Colleen.

Your inclusion of the Autism (ASD) Group makes sense. In fact, I thought of that group first because of the similar behavioral problems.

To clarify:
Our 15-year-old with Chromosome 3 Deletion Syndrome is a girl who resides with her family in northeast Iowa.
I am their cousin in the Twin Cities (of Saint Paul and Minneapolis).
The girl's busy mother (who also is my cousin) is planning to join our discussion when she can.
Together, we are trying to find the best information and resources in Iowa, Minnesota, Wisconsin, and, if necessary, beyond.

Thank you all for your help.


@colleenyoung @mcconnector – Thank you Colleen för the excellent links. @mcconnector – I have a couple of questions- where do you live? Close to major medical centers? I assume the girl was diagnosed by a geneticist. Has she been followed by Developmental specialists and Pediatric Neurologist? In this rare disease there appears to be a varied number of abnormalities in different children. A child’s function and needs also change with time. That’s why I asked if she is seen on a regular basis by specialists. Also, at age 15 your cousin’s education and therapies are still the responsibility of your school district. Do you think she is being educated to reach her best potential?


Hello, Ingegerd.

Thank you for asking your questions, and for the benefit of your knowledge, experience, and guidance.

1. a. I, their cousin, am in the Twin Cities (Saint Paul & Minneapolis) metro region. As you may know, there are numerous medical institutions, including the
University of Minnesota's hospital(s?) and clinics and medical, pharmacy, and nursing schools and department(s?) of genetics, etc.
b. The girl and her mother (both of them my cousins) are in northeast Iowa. They have gone to the University of Iowa and to the Gundersen Lutheran
Medical Center (or Clinic) in La Crosse, Wisconsin, and they could go to the Mayo Clinic in Rochester.
2. Yes, according to the girl's mother, our girl has been diagnosed by a geneticist.
3. You asked: "Has she been followed by Developmental specialists and Pediatric Neurologist?"
My answer: I do not think so; I will ask the mother.
4. You asked: "Do you think she is being educated to reach her best potential?"
My answer: We do not know, which is why we asked the group for educational recommendations. She is showing "behaviors" that are complicating
both her schooling (public) and her life at home with her family.

Thanks for your interest in our situation. We appreciate your assistance.
