What Is A Clonic Seizure?
You may have heard the term clonic seizure during an appointment or seen it written in a report or EEG
The mission of KCNA2 Epilepsy, Inc. is to empower our community through education and awareness while nurturing meaningful connections between KCNA2 families and research professionals who work to find effective treatments and a cure for this rare form of epilepsy.


The vision for KCNA2 Epilepsy, Inc. is for every individual diagnosed with KCNA2 to have a supportive community, along with their family, caregivers and treatment teams who can access ample resources and effective treatments for this rare epilepsy. Ultimately, the collaboration we create between KCNA2 families and researchers will hopefully result in discovering a cure.
KCNA2 is a gene that helps control how brain cells communicate. It affects the flow of potassium in and out of cells; something essential for everything from movement and speech to balance, coordination, and brain activity. When something goes wrong in this gene, the effects can be far-reaching. Symptoms can look like epilepsy, ataxia, spasticity, or developmental delays. But the way each child is affected is unique.
The science is still unfolding. Researchers around the world are working to better understand these variants and what can be done. In the meantime, families are learning, adapting, and advocating with every step.
A KCNA2 diagnosis can feel overwhelming. We created this section to help you get the most out of our website, one step at a time. From understanding the basics of the KCNA2 gene to learning how to build your child’s care team, we’ve gathered the most important first steps in one place.
You’ll find guidance on how to navigate where information is on symptoms, related conditions, how to talk with caregivers, and connect with other families who truly understand. Whether you’re reading from your phone in a hospital waiting room or sitting with a diagnosis at your kitchen table, the Newly Diagnosed page is here to meet you where you are.
Take your time. Come back as often as you need. We’ll be here.
KCNA2 research is gaining momentum. Scientists, clinicians, and advocates are working together to understand how this gene works, what goes wrong, and how to fix it. From new ASO therapies to drug repurposing to mouse models and international registries, the effort is growing.
Your voice helps drive it. Families who join research efforts, share data, and raise awareness are part of the reason we’re seeing progress.

Sleep matters for everyone. But in the KCNA2 community, sleep can feel especially fragile and especially important. Nights are often
