Explore the CAMKII structure
Research in the fields of genetics, biochemistry and pharmacology offer promise for finding new therapies for CAMK2 related disorders and other diseases.
YOU’RE NOT ALONE IN THIS JOURNEY
Receiving a CAMK2 diagnosis can feel overwhelming, confusing, and even isolating — but you are not alone. Many families have stood exactly where you are standing today, and our community is here to walk alongside you every step of the way. Whether you’re a parent, caregiver, or extended family member trying to make sense of what this diagnosis means, we want you to know that there is hope, guidance, and a growing network of people who understand.
This page is designed to help you gain clarity about CAMK2-related disorders, what the diagnosis means for your loved one, and how to take meaningful next steps. Here, you’ll find information written for families — not just scientists — so you can understand what’s happening, what to expect, and where to turn for support. You’ll learn about the biology behind CAMK2, common symptoms, current research, and what families around the world are doing to advocate for care, therapies, and treatments.
Most importantly, you’ll be connected to a community that believes in collaboration, empowerment, and ensuring every family feels informed and supported. No matter where you are in your journey, this is a place to start learning, finding answers, and discovering that you have a team behind you.
UNDERSTANDING CAMK2
Every cell in the body contains genes that provide instructions for making proteins, and the CAMK2 genes are part of a small family of genes that create proteins essential for communication between cells. CAMK2 proteins play a major role in how brain cells send signals, form memories, and support healthy development. Scientists often describe CAMK2 proteins as “signal managers” because they help brain cells respond to changes in calcium, an important chemical messenger.
There are four CAMK2 genes—CAMK2A, CAMK2B, CAMK2G, and CAMK2D—and each one produces a slightly different version of the CAMK2 protein. These proteins work together like a coordinated team. Although CAMK2 is most active in the brain, it is not found there alone. CAMK2 proteins are also present in the heart, muscles, immune system, and other tissues, where they help control processes such as muscle contractions, heart rhythm, and cellular responses to stress. When a CAMK2 gene has a mutation (also called a VARIANT which is a change in its instructions), the protein may not work as expected, which can disrupt brain signaling and may also affect other parts of the body.
EACH PERSON WITH A CAMK2 VARIANT IS UNIQUE
Every child with a CAMK2-related disorder is different. Each genetic change affects CAMK2 proteins in its own way, which means the symptoms and how severe they are can vary from one person to another. Even so, we think of all these conditions together as a “family” of CAMK2 disorders.
Many individuals with CAMK2-related disorders experience developmental delays, challenges with movement and coordination, and behavioral or emotional difficulties, which can sometimes be very intense.
Depending on which CAMK2 gene is affected—A, B, G, or D—some children and adults may also have seizures, stomach or digestion problems, mental health symptoms, or heart issues. These symptoms can have a significant impact on the day-to-day life of the individual and their family.
EXPLAINING THE CAMK2 VARIANT
A CAMK2 genetic mutation usually happens randomly, but in some cases, it can be inherited from a parent. It is not caused by anything a parent did or by environmental factors. Most families will not have more than one child with the same mutation, though rare exceptions exist.
Everyone carries many genetic differences that make us unique. Most of these changes are harmless and do not affect health or how important proteins work—they simply contribute to human diversity.
The CAMK2 protein is very important in the brain, and sometimes in the heart. When a mutation affects this protein, it can change how it functions and lead to noticeable challenges or disease. Children with a CAMK2 mutation are simply affected because this important gene was altered, whether the change occurred randomly or was inherited.
On genetic reports, you may see notations like “c.” and “p.”: the “c.” (coding DNA) shows the exact change in the DNA sequence, while the “p.” (protein) describes how that DNA change alters the protein itself, helping doctors and researchers understand the mutation’s effect. Keeping a copy of your genetic report with the c. and p. notations is important because it provides precise information about the mutation, helping doctors, researchers, and your care team make informed decisions about treatment, monitoring, and participation in research or clinical trials.
UNDERSTANDING GENE VARIANTS
A gene variant, or mutation, is a permanent change in a person’s DNA that can sometimes cause health or developmental challenges. If your child has developmental differences and a CAMK2 diagnosis, it usually means a change in one of the four CAMK2 genes is the cause.
These gene changes are being discovered more frequently thanks to new testing methods like whole-exome sequencing. Instead of giving each disorder a separate name, families now usually describe it by the specific gene affected, for example: “My child has a variant in the CAMK2A (or B, G, or D) gene.”
So far, around 350 people worldwide have been identified with CAMK2 variants. As genetic testing becomes more common, many more children with autism, seizures, or developmental delays are expected to be diagnosed with CAMK2-related differences.
ADVANCING THERAPIES
At the CAMK2 Therapeutics Network, a major part of our mission is to find effective treatments for children with CAMK2-related conditions. While there are currently no specific therapies, we are actively working with research partners to study existing FDA-approved medications that might help restore normal CAMKII function and reduce symptoms. We are also collaborating with partners to develop gene therapies that could directly target the underlying cause of these conditions.
Our goal is to accelerate the development of targeted CAMKII therapies and gene-based treatments that not only address symptoms safely but also have the potential to transform the lives of affected children.
