Newly Diagnosed
What is 16p11.2?
16p11.2 refers to a small section of chromosome 16 that contains important genetic instructions. Everyone has two copies of this chromosome region—one from each parent. A 16p11.2 diagnosis means that this segment is either:
- Deleted (one copy is missing), or
- Duplicated (an extra copy is present)
These genetic differences can influence development, learning, behavior, and health—but they affect each person differently.
What’s Important to Know
- Nothing you did caused this.
- This diagnosis does not define your child or predict their future.
- Two people with the same diagnosis can look very different in strengths, challenges, and support needs.
What Might This Mean for My Child?
Children and adults with 16p11.2 may experience some of the following:
- Developmental delays (speech, motor skills, learning)
- Autism spectrum traits
- Differences in attention, behavior, or emotional regulation
- Learning differences
- Growth or weight changes
- Seizures or other medical concerns (for some individuals)
Not everyone experiences all of these, and many individuals have significant strengths—creativity, humor, persistence, empathy, curiosity, or deep focus in areas they love. A diagnosis is not a label—it is information that helps unlock understanding and access support.
A diagnosis can feel heavy at first—but it can also become empowering. Many families discover that having a name for what they’re experiencing opens doors to support, clarity, and community. Your child is still the same child you love. This is simply one more piece of their story.
