KCNT1-related epilepsy: What to do next when your child has been diagnosed

What is KCNT1-related epilepsy?

KCNT1-related epilepsy is a specific kind of epilepsy caused by changes (variants) in the KCNT1 gene. Genes are instructions that the body uses to grow and develop, and KCNT1 plays an important role in how electrical signals are sent in the brain. Genetic changes in the KCNT1 gene can prevent brain signals from functioning properly, leading to seizures and other problems.

There are two main types of KCNT1-related epilepsy, based on when symptoms begin.

Epilepsy of Infancy with Migrating Focal Seizures (EIMFS) is the earlier and more severe form. Seizures typically begin before a baby is 6 months old, and are called "migrating" because they shift from one part of the brain to another. This can impact brain development and cause developmental delays or regression. You may see EIMFS referred to in medical records by older names, including Early Infantile Epileptic Encephalopathy (EIEE), Developmental and Epileptic Encephalopathy (DEE), Malignant Migrating Partial Seizures of Infancy (MMPSI), or Migrating Partial Epilepsy of Infancy (MPEI).

Sleep-Related Hypermotor Epilepsy (SHE) is a milder form that tends to start later in childhood, often before the teen years. Most seizures happen during sleep and can look like intense movements or night terrors. This condition was previously called Autosomal Dominant Nocturnal Frontal Lobe Epilepsy (ADNFLE), so you may see that name in older records or literature.

Knowing what type of KCNT1-related epilepsy your child has is important to understand what symptoms to expect and if there is a risk for family members to have similar symptoms.

Should I get a second opinion for a KCNT1-related epilepsy diagnosis?

Rare diseases require specialized expertise. Consider seeking a second opinion from a physician who focuses specifically on seizures, like a pediatric epileptologist. A fresh perspective can confirm the diagnosis, reveal additional treatment options, or simply provide reassurance about your care plan.

For many rare diseases, it can be hard to find a specialist with relevant experience. You can try asking providers you have seen, referring to community resources (see Section 5 below), or consulting a genetic counselor. The KCNT1 Epilepsy Foundation also has a "Find a Doctor" tool with professionals who have treated patients with KCNT1-related disorders.

What does a genetic counselor do when my family has received a KCNT1-related epilepsy diagnosis?

Certified Genetic Counselors have completed a program of study focused on understanding and providing information about genetic disorders. A genetic counselor can help you understand the genetic aspects of your child's diagnosis, what it means for your family, and whether testing is recommended for siblings or other relatives.

Genetic counseling can take place in person or in a telemedicine visit. The National Society of Genetic Counselors offers a tool for finding a genetic counselor.

Should other family members undergo genetic testing for KCNT1-related epilepsy?

In KCNT1-related epilepsy, the inheritance pattern depends on the specific subtype of the condition:

In the EIMFS (severe infant form), the condition is most often caused by a new (de novo) variant in the KCNT1 gene. This means the genetic change arises newly in the child and was not inherited from either parent. In these cases, the risk of the same condition occurring in a sibling is generally very low, though not zero.

In Sleep-Related Hypermotor Epilepsy (SHE), some children with SHE inherit the genetic change from a parent, who may have symptoms. If the genetic change was found to be inherited from a parent, each child has a 50% chance of inheriting the change and potentially developing associated symptoms.

Speaking with a genetic counselor about your child's diagnosis can help determine if testing is recommended for parents, siblings, or other family members. Your genetic counselor can explain your family's specific situation, who should consider testing, and the best timing for those tests.

What should I ask my child's neurologist about a KCNT1-related epilepsy diagnosis?

Knowing what to ask can help you make the most of appointments with specialists. You can use these questions as a guide to discuss care that is specific to your child's diagnosis.

For questions specific to your child's situation, Citizen Health offers a free doctor's appointment preparation tool that incorporates your child's KCNT1-related epilepsy medical records and provides appointment preparation suggestions through an AI chat interface.

What symptoms should we monitor for KCNT1-related epilepsy?

Every person with a KCNT1-related condition is a little different, and symptoms can vary from one individual to the next. While every person's experience is unique, the following are some commonly seen symptoms associated with each subtype:

EIMFS:

• Seizures
• Breathing pauses or irregular breathing
• Small head size (microcephaly)
• Developmental delays
• Feeding and swallowing difficulties
• Low muscle tone (floppiness) in infancy, stiffness or spasticity in arms and legs over time
• Involuntary movements, like writhing or jerking of limbs
• Vision problems
• Constipation, reflux, or bladder problems
• Heart rhythm problems or abnormal blood vessels connecting the heart and lungs

SHE:

• Seizures, often occurring during sleep
• Abnormal nighttime movements, which can look like intense night terrors
• Slowing or loss of developmental skills
• Learning disabilities or challenges in school
• Behavioral, psychiatric, or emotional challenges such as anxiety, depression, or ADHD-like symptoms

What is the expected progression of KCNT1-related epilepsy?

The progression of KCNT1-related disorders depends on the subtype:

• Most children with EIMFS develop seizures before 6 months of age. Seizures often increase in frequency quickly and can become nearly constant. Once seizures begin, development typically slows or stops, and many children lose skills they had already gained (called regression). Over time, many children will need significant support with mobility, communication, feeding, and daily care. Some children are able to achieve limited communication or movement with the help of therapies and adaptive equipment, and goals are best set individually with your care team.
• Children with SHE develop seizures later, often in early to middle childhood before teenage years. Seizures mostly happen during sleep in the first decade of life. SHE can involve a period of regression, where children may lose skills they had previously developed, but it is generally milder than in EIMFS. Many children struggle with learning, behavior, or emotional regulation, though symptoms can vary widely, even within the same family.

What treatments are available for KCNT1-related epilepsy?

There is currently no cure for KCNT1-related disorders. Treatment focuses on managing symptoms and improving quality of life. Treatment is highly individual, and what works for one child may not work for another. Working closely with your child's care team is the best way to find the right combination of treatments for your child.

• Anti-Seizure Medications: Several medications have been used to help manage seizures, including stiripentol, benzodiazepines, levetiracetam, quinidine, and others. A combination of seizure medications is typically prescribed depending on the type of seizures present.
• Ketogenic Diet: A high-fat, low-carbohydrate diet that sometimes helps reduce seizures for some individuals.
• Implantable Devices: A Vagus Nerve Stimulator (VNS) is a small device surgically implanted in the chest that sends gentle electrical signals to the brain.
• Therapies and Early Intervention: Children may benefit from working with a range of therapists and specialists early on. For more information on available therapies, see Section 3.
• Targeted Treatments: Research into additional treatments, including RNA and gene therapy approaches, is actively ongoing. Some emerging therapies include antisense oligonucleotides (ASOs) and RNA (di-siRNA) therapies, which aim to address the root cause of KCNT1-related disorders, rather than treat the symptoms. Staying connected to the KCNT1-related disorder research community is one of the best ways to stay informed about emerging options (see below).

What healthcare providers should be on my child's care team for KCNT1-related epilepsy?

Your child's KCNT1 care team is the group of providers who work together to support your child's health, development, and quality of life.

KCNT1-related epilepsy can affect multiple body systems, so your child's care team will likely extend well beyond a single doctor, and building it early matters, as waitlists for specialty and therapeutic services can be long.

Your team may include specialist physicians such as a pediatric epileptologist (epilepsy specialist), neurologist (brain), cardiologist (heart), gastroenterologist (digestive system), pulmonologist (lungs), ophthalmologist (vision), or orthopedist (musculoskeletal system), as well as a geneticist who can help manage the complexity of a rare disease diagnosis.

Therapeutic providers, such as a physical therapist (mobility and motor skills), occupational therapist (daily living skills and fine motor development), speech-language pathologist (communication and feeding), or behavioral therapist (supporting emotional regulation and adaptive behavior), are equally important members, supporting your child's development, communication, and daily functioning. Ask your doctor which providers make sense for your child's specific needs. For a deeper look at therapeutic services and how to access them, see Section 3.

Finding clinical trial opportunities & supporting research into KCNT1-related epilepsy

When you participate in research, you help your child and other families in the future. Medical research studies can be very different from each other. Some test new treatments, while others are "natural history studies" that just collect information about a disease's impact over time.

Clinical trials are research studies that help doctors find new treatments. Some trials test new medicines or therapies that aren't available yet. Even if you may choose not to participate, it can be good to know what options exist for KCNT1-related epilepsy. Your child's doctor or disease organization can help you find trials that might be a good fit. The KCNT1 Epilepsy Foundation is a good source for staying up to date on current studies, and the U.S. government maintains a registry at clinicaltrials.gov.

Natural history studies are designed to help researchers learn more about the condition. This information is important for creating future treatments. Traditional natural history studies can involve additional medical appointments over the course of several years. Citizen Health is partnering with the KCNT1 Epilepsy Foundation to build a unified dataset and accelerate research efforts for KCNT1-related epilepsy. Families can participate by securely sharing de-identified data abstracted from your medical records to help researchers better understand KCNT1. No additional appointments are needed to participate. You can learn more about and sign up here.

Patient registries collect health information from people with KCNT1-related epilepsy to help research move faster and connect families with clinical trials. Registries also show researchers and drug companies that families are engaged and want to help develop new treatments, which can bring more funding and research attention to a disease. Some diseases have more than one registry you can join. Patient Advocacy Groups typically establish and maintain patient registries for specific rare diseases. (See Section 5 below to learn more).

Organizing and maintaining your child's medical records for KCNT1-related epilepsy

Rare disease patients see many different doctors, often across different medical and technological systems that may not talk to each other. Unfortunately, that means the burden often falls on caregivers to track care holistically, identify "gaps," and make sure nothing gets missed. Keeping your records as organized and centralized as you can from early on is likely to improve your ability to manage your child's care down the road.

You can start by creating a one-page sheet with your child's diagnosis, current medications, allergies, and emergency contacts. Bring this sheet to every appointment. It can really help in emergencies or when you see a new doctor.

Many caregivers establish one (or several) records binder(s) in which they keep track of appointments, medication updates, symptoms, and other ongoing medically relevant information.

We also encourage caregivers to consider Citizen Health's free tools for centralizing, managing, accessing, and extracting key information from health records. Our system will collect all your health records, across doctors and health systems, making them available on our secure online platform that can provide answers in real time based on questions you ask (like "What medications has my child been prescribed in the past year?" or "When did we last see an orthopedist?")

As a company built by rare disease caregivers, we aim to overcome the need for physical records binders. But ultimately the important question is what works for you and your family.

Before age 3: Understanding early intervention services for children with KCNT1-related epilepsy

Early intervention provides therapies and support for children from birth to age 3 who have delays or disabilities. Services may include physical therapy, occupational therapy, speech therapy, and other developmental support.

Every state has an early intervention program, and you can ask for an evaluation even if your child doesn't have a formal diagnosis yet. In some states, early intervention programs are called "birth to three", "early steps", or "first steps".

It's never too early to search for early intervention services in your state. Learn more from ECTA, the Early Childhood Technical Assistance Center.

3 & up: School services for children with KCNT1-related epilepsy

IEPs and 504 plans

When your child turns 3, they move from early intervention to school-based services. An Individualized Education Program (IEP) is a legal document that describes the special instruction, therapies, and support your child needs to learn at school.

A 504 plan provides accommodations for students who don't need special instruction but need support because of a disability. Understanding your rights and these plans helps make sure your child gets the right services throughout their school years.

Communicating with your school

Building a good relationship with your child's school team is important. You know your child better than anyone, and that knowledge is incredibly valuable. Come to meetings prepared with information about your child's needs, share your concerns and hopes openly, and never hesitate to ask questions if something isn't clear.

You are an equal and essential member of this team. Other members of your rare disease community can also be valuable resources for navigating your child's school experience.

Assistive devices and equipment for KCNT1-related epilepsy

Depending on your child's needs, assistive technology and adaptive equipment can help with independence, communication, and quality of life. This might include seizure monitors, communication devices (Augmentative and Alternative Communication or AAC), mobility equipment, positioning supports, or adaptive toys and tools. Your therapists can recommend the right devices, and many are covered by insurance or available through school programs.

Some devices and equipment can be expensive but can very often be covered by insurance. If coverage is denied, be sure to talk to your doctors about writing an appeal letter or a Letter of Medical Necessity. These documents can be critical for getting insurance coverage for devices and equipment.

Respite care

Caring for a child with complex medical needs is hard work, and taking breaks is important for your health and your family's wellbeing. Respite care provides temporary relief, giving you time to rest, handle other responsibilities, or just recharge. Options range from a few hours with a trained caregiver to overnight or weekend programs.

Respite isn't a luxury. It's a necessary part of taking care of your family long-term. The non-profit Access to Respite Care and Help (ARCH) provides guidance on how to find a respite care provider.

Building your support systems as a KCNT1-related epilepsy caregiver

Being a caregiver to a child with KCNT1-related epilepsy is a heavy responsibility. You can't do it alone, and you don't have to. Building a network of support including family, friends, medical providers, therapists, other parents, and community resources, creates a safety net for hard days as well as people to celebrate victories with.

When asking for help, it helps to be specific: people want to support you but often don't know how. Whether it's meals, watching your other children, or just someone to listen, letting others help is good for everyone.

Don't forget about support for other family members! If your child has siblings check out the Sibling Support Project.

Medicaid and Social Security eligibility for KCNT1-related epilepsy

Even if your family income exceeds typical Medicaid limits, children with KCNT1-related epilepsy may qualify for Medicaid through special pathways designed for those with disabilities or significant medical needs.

A program called Katie Beckett or TEFRA waivers allows children with disabilities to qualify for Medicaid based on their own income rather than family income. Additionally, children with significant functional limitations may qualify for Supplemental Security Income (SSI), which provides monthly payments and often automatically qualifies them for Medicaid. These programs can provide crucial coverage for therapies, equipment, and services private insurance won't cover.

Learn more about Medicaid in your state through this interactive map from NORD.

ABLE savings accounts for KCNT1-related epilepsy

On that note, if your child qualifies for SSI, they may also be eligible for an ABLE (Achieving a Better Life Experience) account. ABLE accounts are tax-advantaged savings accounts specifically designed for people with disabilities that are opened in a child's name but do not count against the $2,000 asset limit that typically applies to programs like SSI and Medicaid.

Understanding your insurance coverage for KCNT1-related epilepsy

What's covered

• Your insurance policy determines what services, therapies, equipment, and medications are covered for your child. Start by reading your plan documents to understand your benefits, deductibles, co-pays, and out-of-pocket maximums. Call your insurance company's customer service or case management department as many insurers assign case managers to children with complex medical needs who can help you understand your coverage.
• Don't assume something isn't covered until you've asked. Many families are surprised to learn what benefits are available when properly documented.
• Keep notes of every call you make, including the date, time, person you spoke with, and what they said. This documentation can be very helpful later.
• Most children's hospitals also have a financial counselor or patient navigator who may be able to help with insurance or financial coverage issues.

Therapy & rehabilitation

• When considering insurance coverage for therapies and rehabilitation services, make sure to see if your plan has a cap for the number of therapy visits per year. Many children with complex needs will exceed that cap and appeals or additional insurance coverage plans may be needed.

Medical equipment

• If your child needs durable medical equipment such as a wheelchair, walker, orthotics, or at home equipment, getting insurance coverage for that equipment will likely require prior authorization or a letter of medical necessity.

Gene therapy

• As research evolves, gene therapy or disease targeted treatments may become accessible for KCNT1-related epilepsy. There are different kinds of targeted treatments which aim to fix the cause of the particular condition by fixing the instructions for our bodies, rather than treating the downstream symptoms. Since this technology is newer, as therapies move from clinical trials to FDA approval, there can sometimes be challenges getting insurance to cover the treatments. Understanding how coverage works, what challenges exist, and how to advocate for approval is essential for families whose children may benefit from these groundbreaking treatments.

Denials & appeals

• Insurance companies often deny coverage for therapies, equipment, or medications at first but denials can often be overturned with the right documentation. If coverage is denied, you have the right to appeal, and many families win their appeals.
• An effective appeal letter includes: your child's diagnosis and how it affects their daily life, specific medical reasons from doctors explaining why the service or item is necessary, references to your insurance policy language that supports coverage, research or medical guidelines supporting the treatment, and a clear request for reconsideration. Many patient organizations and hospital financial counselors can help you write strong appeals. You can even appeal multiple times, and many families win on their second or third attempt. You're advocating for your child, and persistence often pays off.

Non-discrimination protections for KCNT1-related epilepsy

The Genetic Information Nondiscrimination Act (GINA) is a federal law that protects you from genetic discrimination in health insurance and employment. Health insurance companies cannot use genetic information to deny coverage, raise your premiums, or determine eligibility. However, GINA does not cover life insurance, disability insurance, or long-term care insurance. Employers cannot use genetic information when making hiring, firing, or promotion decisions. Understanding these protections can give you confidence in pursuing genetic testing and sharing results with your child's healthcare providers without fear.

Learn more about these protections from the American Society of Human Genetics.

Why connect with other KCNT1-related epilepsy families?

Finding and connecting with families who have walked in your rare disease shoes can be life-changing. Other parents navigating the same diagnosis can offer practical advice, emotional support and hope based on their shared experience. They can understand the daily challenges and the victories, big and small, in ways that others can't. Disease-specific communities often become a lifeline and a source of hope that remind you that you are not alone.

Local KCNT1-related epilepsy support groups

Your genetic counselor or other healthcare provider may be able to connect you with local families in your area. It is totally appropriate to ask your providers if they know of any local families who might be willing to connect with you for a phone call or even a play date.

Some rare diseases are so exceptionally rare that it might not be possible to connect locally with another person with the same rare disease. But collectively, rare diseases are not that rare! Connecting with broader rare disease groups is another great option. Many states and communities have organizations that support all rare diseases.

Patient advocacy groups (PAGs) specific to KCNT1-related epilepsy

Patient advocacy groups exist for many rare diseases and serve as a central hub for connections, reliable information, research updates and advocacy efforts. These organizations work to advance research, improve care standards, raise awareness, and support families. They often host conferences, maintain family directories or registries, fund research, provide educational resources, and fight for policies that benefit the community.

Connecting with your disease's advocacy organization gives you access to experts, researchers, and a network of families while contributing to the larger mission of finding treatments and cures.

Citizen Health partners with KCNT1 Epilepsy Foundation, an organization dedicated to accelerating treatments and expanding understanding across the evolving spectrum of KCNT1-related conditions through collaborative research, clinical readiness, and family empowerment. Learn more to join the community here.

Disease-specific conferences and events

Many patient advocacy groups will help spread awareness through conferences and events. These can include in person events or online events and are great opportunities to connect with others and to stay on the cutting edge of new research opportunities.

Attending a conference focused on your child's condition can be transformative. These gatherings bring together families, researchers, doctors, and advocates in one place. You'll hear about the latest research, learn from medical experts, meet families at different stages of the journey, and let your child connect with others like them.

Many families describe their first conference as the moment they felt less alone. While attending may require travel and expense, many organizations offer scholarships or financial assistance to help families participate. If you can go, it's often worth it.
