Navigating Proximal 16p11.2 Microdeletion Syndrome

At a Glance

Proximal 16p11.2 microdeletion syndrome is a genetic condition with variable expressivity, meaning it affects every child differently. It does not typically shorten life expectancy, and utilizing early intervention with a multidisciplinary care team can greatly improve developmental outcomes.

Receiving a diagnosis of proximal 16p11.2 microdeletion syndrome for your child often comes with a whirlwind of emotions. Whether you are feeling relief at finally having an answer, panic about what the future holds, or a mixture of both, your feelings are completely valid.

The most important thing to know right now is that this genetic diagnosis does not define your child. While the 16p11.2 microdeletion is associated with certain developmental and health challenges, it is characterized by variable expressivity [1]. This means that every child with this deletion is unique, and they will write their own story. The condition is not generally considered to shorten life expectancy, and early intervention can make a profound difference [2].

How to Use This Guide

This guide is designed to empower you with evidence-based information so you can effectively advocate for your child. It is divided into three key areas:

01

The Biology and Genetics of 16p11.2 Microdeletion

Learn about the biology and genetics of 16p11.2 microdeletion. Understand lab reports, inheritance, de novo vs inherited cases, and why symptoms vary.

02

Understanding Symptoms and Development

Learn about symptoms of proximal 16p11.2 microdeletion syndrome in children, including speech delays, autism, macrocephaly, early-onset obesity, and more.

03

Medical Roadmap: Monitoring and Care

Learn about the medical roadmap for 16p11.2 microdeletion syndrome. Discover recommended baseline evaluations, ongoing surveillance, and long-term care plans.

As you navigate this journey, remember that you are building a multidisciplinary care team to support you. You do not have to have all the answers today. Start by taking a deep breath, reading through these resources at your own pace, and preparing the questions you want to ask your doctors.

Common questions in this guide

What does a proximal 16p11.2 microdeletion diagnosis mean for my child's future?
Because the condition has variable expressivity, every child is unique and will have their own specific needs. While it is associated with developmental and health challenges, early intervention therapies can make a profound difference in helping your child thrive.
Will proximal 16p11.2 microdeletion syndrome shorten my child's life?
No, this genetic condition is not generally considered to shorten life expectancy. With proper monitoring and a dedicated care team, individuals with this deletion can live healthy, full lives.
Who should manage my child's care for a 16p11.2 deletion?
Your child will benefit from a multidisciplinary care team tailored to their specific needs. It is important to establish one provider, usually your pediatrician, to act as the coordinator or 'quarterback' for the various specialists involved in your child's care.
How can I better understand the genetic lab reports for my child?
A genetic counselor is an excellent resource for families. They can help you interpret the complex terminology on your child's lab reports, explain how the genetics work, and discuss testing options for the rest of your family.
