There is no correct way to respond to a diagnosis like this. Some families feel relief at finally having a name for what they have been observing. Others feel grief, shock, fear, or a mix of all of these at once.
Whatever you are feeling right now is valid. This is hard. And it is also navigable with the right support around you. When you are ready, this guide will help you understand the practical steps ahead. There is no rush to get through all of it today.
If your child has been identified as having an SCN2A variant, they have a change in a gene called SCN2A that affects how their brain develops and functions. SCN2A variants can cause a range of conditions from early infantile epilepsy to autism spectrum disorder with minimal seizure activity depending on the specific nature of the variant.
If your child has a broader diagnosis of DEE (Developmental and Epileptic Encephalopathy) with a specific genetic cause, the underlying gene matters for understanding what to expect and which treatments are likely to help.
Ask your neurologist or geneticist whether your child's variant is a gain of function or loss of function variant. This matters significantly for treatment decisions, some anti-seizure medications that help one group may worsen outcomes in the other.
Genetic reports often include language like "pathogenic," "likely pathogenic," "variant of uncertain significance (VUS)," or "de novo." If you have received a genetic report that you don't fully understand, a genetic counsellor can walk you through what it means for your child and your family.
SCN2A Australia can link you with genetic counsellors and families who have navigated similar results {e.preventDefault();navigate('genetics');}}>you do not need to interpret this alone.
Managing an SCN2A-related condition or DEE typically involves a team of specialists working alongside your child and family. In the early stages, your team is likely to grow and that can feel overwhelming.
A typical care team for a child with SCN2A or DEE may include:
You do not need all of these from day one. Your medical team will guide referrals based on your child's specific presentation. The key is to start building relationships with the right specialists early wait times for paediatric specialists in Australia can be long.
If your child is young, early intervention services, including OT, speech, and physiotherapy, are consistently shown to support better developmental outcomes. In Australia, access to early intervention services can be funded through the NDIS, depending on eligibility.
If your child has seizures, seizure safety is one of the most immediate priorities. Your neurologist will guide you on medication, seizure first aid, and when to call for emergency help. Some key starting points:
Stay calm. Time the seizure. Keep your child safe from injury. Do not put anything in their mouth. Most seizures stop on their own within a few minutes.
Your neurologist will tell you when to call an ambulance. This varies depending on your child's condition and seizure type make sure this advice is clear and written down.
Medication selection for SCN2A requires careful consideration of whether your child has a gain or loss of function variant. Some medications are contraindicated for certain variant types. Always make sure any treating clinician, including in an emergency setting knows your child's SCN2A variant type and any medications that should be avoided.
One of the most valuable things you can do in the early weeks after diagnosis is connect with another family who has been where you are.
SCN2A Australia facilitates peer connections linking families with others who have children with similar presentations, similar ages, or similar challenges. There is nothing quite like speaking with someone who genuinely understands.
We also host regular virtual meetups and an annual family event where families can connect in person.
The SCN2A Insights Registry is one of the most meaningful things your family can do to help advance understanding and treatment of SCN2A-related conditions.
The registry collects information from families with SCN2A variants to build a picture of the condition how it presents, how it progresses, and what helps. This data directly informs research directions and clinical trial design.
Participating in the registry does not commit you to anything else. Your information is de-identified and used for research purposes only. And by joining, you become part of a global community of families contributing to a future where better treatments are possible.
Caring for a child with a complex medical condition has significant practical and financial implications. In Australia, the main avenues for support include:
Children with SCN2A-related conditions or DEE may be eligible for NDIS funding, which can cover therapies, equipment, support workers, and other needs. Navigating the NDIS can be complex SCN2A Australia links you to families who have been through it and resources that make the process clearer.
Centrelink offers a range of payments for carers, including Carer Payment and Carer Allowance. These are income-tested and based on the level of care required.
If the diagnosis affects your ability to work, your employer may offer flexible arrangements, and there are government supports available for carers.
This bears saying clearly: caring for a child with a complex condition is one of the hardest things a person can do, and your wellbeing matters, not as an afterthought, but as a genuine priority.
Many families find that the initial period after diagnosis is intense absorbed by appointments, decisions, and adjusting to a new reality. In time, many also find a rhythm, a community, and a resilience they did not know they had.
Give yourself permission to ask for help. Accept support when it is offered. And when you are ready, SCN2A Australia can connect you with carer support resources, peer connections, and a community who understands.
Print this. Stick it on the fridge. Tick things off as you go. Don't try to do them all at once.
A seizure is caused by a sudden surge of abnormal electrical activity in the brain. In SCN2A-related conditions and other DEEs, this abnormal activity arises because the underlying gene change affects how brain cells communicate and regulate their electrical signals.
Seizures can look very different depending on which part of the brain is affected, what is happening in that region, and the age and development of the child. A single child may experience more than one type of seizure, and the pattern may change over time.
Not every child with an SCN2A variant will have all, or any, of these seizure types. Your child's specific presentation will depend on their variant, their age, and many other factors. Your neurologist is the best source of guidance.
General guidance. Your neurologist will provide specific instructions tailored to your child's condition and seizure type.
Anti-seizure medications (ASMs) are the primary treatment for seizures in SCN2A and DEE. Choosing the right medication, and avoiding the wrong one, requires knowing your child's specific SCN2A variant type.
SCN2A variants can be broadly classified as gain of function (GoF) or loss of function (LoF):
This is not a theoretical distinction. There are documented cases of children with LoF variants whose seizures worsened after being prescribed sodium channel-blocking medications that are standard treatment for other epilepsy types.
It is not uncommon for seizures in SCN2A and DEE to be difficult to control with a single medication, or to require adjustment over time. If your child's seizures are not responding, discuss with your treating team:
Some children with SCN2A or DEE have rescue medications, medications given during or after a prolonged seizure to stop it before it becomes a medical emergency. These are typically fast-acting medications administered by carers (not only by medical staff), given at home or in the community.
Common rescue medications include midazolam (given into the cheek or nose) and diazepam (rectal). Your neurologist will prescribe a rescue medication if it is appropriate, and provide training in when and how to administer it.
If your child has a rescue medication, make sure everyone responsible for their care, school staff, extended family, regular carers, knows what it is, where it is kept, and when and how to use it.
Keeping a clear record of your child's seizures is one of the most practical things you can do to support their care. A seizure diary helps your treating team identify patterns, assess medication effectiveness, and make informed adjustments.
A seizure record should note:
Many families use smartphone apps designed for seizure tracking. Your neurologist or epilepsy nurse may recommend one, or SCN2A Australia can suggest options used by our community.
Managing seizures is important, but so is maintaining quality of life. The goal of treatment is not zero seizures at any cost; it is to find the best balance between seizure control and the side effects of medication, and to support your child's development and wellbeing.
Families often find that it takes time and adjustment to reach a medication regimen that works. That process can be exhausting and sometimes disheartening. Connecting with other families who have navigated similar challenges, and who know what this feels like, is one of the most valuable things SCN2A Australia can offer.
In developmental and epileptic encephalopathies, the underlying gene change affects how the brain develops, not just how it generates seizure activity. Developmental differences in children with DEE are not simply a secondary effect of seizures; they are part of the condition itself.
This distinction matters because it means that even when seizures are well controlled, developmental support remains important. Conversely, accessing developmental therapies early, before or alongside seizure treatment, is genuinely valuable and not something to be deferred.
The range across the SCN2A community is wide. Some children have significant intellectual disability and complex communication needs; others have mild developmental differences alongside good language and social development. Where your child sits depends on their specific variant, the timing and nature of any seizure activity, and many individual factors.
Research consistently shows that early intervention, accessing therapies and developmental support as early as possible, leads to better outcomes for children with neurodevelopmental conditions.
For children under 9, the NDIS Early Childhood Approach provides a pathway to early funded supports without requiring a formal NDIS plan. For older children, NDIS funding through a standard plan can cover therapy costs.
Early intervention typically involves some or all of the following, depending on the child's needs:
The earlier these supports begin, the more the developing brain can benefit. This does not mean that intervention after early childhood is not valuable, it is, but early access tends to have the greatest developmental impact.
Supporting a child with SCN2A or DEE through school requires collaboration between the family, the school, and the child's therapeutic team. Most states and territories have provisions for additional educational support, including:
Many families find that advocating effectively requires persistence and clear documentation from the child's treating team. OTs, speech pathologists, and psychologists can provide written reports that support access to school-based funding and adjustments.
SCN2A Australia can help you navigate the school support landscape and connect you with families who have experience advocating in your state or territory.
For families with older children and young people with SCN2A or DEE, thinking ahead to adulthood is an important and often daunting process. Questions about post-school options, supported living, employment, and adult health care are ones that many families begin confronting in the teenage years.
SCN2A Australia is developing resources for this stage. In the meantime, we encourage families to:
