Genes act as the instruction manual for how the brain grows, develops, and functions. When a gene carries a change, called a genetic variant, it can contribute to conditions like epilepsy, developmental delay, movement disorders, and structural brain differences.
Only a few decades ago, genetic testing was slow, expensive, and reserved for rare cases. Today, tools like whole exome sequencing and whole genome sequencing have become one of the first recommendations after a neurological condition is diagnosed or suspected in a child. But the science is only half the picture. Without expert interpretation, a genetic report can feel like reading a foreign language, and families can walk away more confused than informed.
That is where our genetic counselor comes in
Pre-Test
Before Testing: Pre-Test Genetic Counseling
Before any test is ordered, our genetic counsellor meets with your family to:
- Collect a detailed medical and family history
- Explain how genetic variants occur, including why a child can have a genetic condition with no family history
- Walk through the benefits, limitations, and possible unexpected findings of testing
- Answer your questions so you can make the decision that is right for your child
The goal is informed consent, not pressure. Some families decide to move forward with testing. Others take time, or decide it is not right for them. Both paths are supported.
Post-Test
After Testing: Post-Test Genetic Counseling
Once results come back, we meet again to translate the report into plain language. Every appointment is individualized, but most post-test visits cover:
- What the result means for your child's diagnosis and care
- Treatment implications, including targeted therapies, gene therapies, or clinical trials that may now be options
- Family planning questions for parents considering future children
- How to share genetic information with relatives who may also be affected
- Emotional support for the adjustment that often follows a new diagnosis
When Results Are Inconclusive
Genetics is not an exact science. Some tests come back without a clear answer, or with variants of uncertain significance. When that happens, we help families understand what is known, what is not, and what comes next, including periodic re-analysis as the field evolves and new discoveries are made.
How Genetic Counseling Improves Care
A confirmed genetic diagnosis can change a child's care plan in meaningful ways:
- Predicting outcomes so families can plan ahead
- Guiding medication and treatment choices based on the specific genetic cause
- Connecting families to specialists whose expertise matches the diagnosis
- Opening doors to targeted therapies, gene therapies, and clinical trials
- Informing relatives who may benefit from their own testing or monitoring
By combining neurological expertise with genetic counseling under one roof, and coordinating with our Clinical Pharmacy Team, NJPNI families receive personalized care that evolves as their child grows and as the science advances.
Jillian Kirk, CGC is a certified genetic counselor at NJ Pediatric Neuroscience Institute. She works directly with our pediatric neurologists to help families navigate genetic testing, interpret results, and understand what those results mean for their child's care and their family's future.

Genetic counseling is commonly recommended when a child has or is being evaluated for:
- Epilepsy and seizure disorders
- Developmental delay or intellectual disability
- Autism spectrum presentations with neurological features
- Movement disorder
- Hydrocephalus and structural brain differences
- Neuromuscular conditions
- Unexplained neurological regression
- Family history of a known genetic neurological condition
If you are unsure whether genetic counseling is appropriate for your child, our team can help you decide during an initial consultation.
If your child has been diagnosed with a neurological condition, or if genetic testing has been recommended and you want expert guidance before moving forward, we are here to help.
