Happy holidays! Please be advised that in-transit patient samples will be held by the carrier on Dec. 25 and received by our lab the next day. Kit orders placed on Dec. 25 will be sent on Dec. 26. Our genetic counseling services, client services, and billing services will be unavailable Dec. 24-25; please leave us a message at 888-729-1206 or support@genedx.com and we will respond when we return.

A genetic condition may be hiding behind epilepsy

Identifying the root cause of a child’s unexplained seizures can be as simple as a cheek swab. A genetic diagnosis is important because it can guide clinical decisions for patients with epilepsy:1

  • In up to 80% of cases, a genetic diagnosis has implications for treatment and management.
  • Patients can experience up to 90% seizure reduction in some cases.

Exome: Recommended by guidelines as a first-line test

Exome sequencing is recommended as a first-line test for individuals with unexplained epilepsy by the National Society of Genetic Counselors and endorsed by the American Epilepsy Society.2

Starting with exome sequencing is more likely to deliver a genetic diagnosis than multi-gene panels. That’s because 57% of seizure-related genes are not included on many commercially available epilepsy panels3—but are covered by GeneDx exome sequencing. What’s more, exome sequencing is twice as likely to lead to a diagnosis when compared to chromosomal microarray (CMA).1

In other words, the traditional tests only look at a narrow slice of the possible genetic causes for epilepsy.  Today, more doctors are turning to GeneDx exome sequencing for answers.

According to the World Health Organization, “It is estimated that up to 70% of people living with epilepsy could live seizure-free if properly diagnosed and treated.”4

Yet all the statistics in the world can’t bring home the importance of an exome test like a parent can.

Helping to remove cost as a barrier to exome testing

Many insurance companies recognize the importance of exome sequencing for patients with epilepsy, and their coverage policies reflect that understanding.

In addition, GeneDx’s Epilepsy Partnership Program provides even greater access to exome testing for eligible patients by creating an option if their health insurance company denies their claim or if they are uninsured.

Take a guideline-driven approach. Start with exome.

Every day, GeneDx helps patients with seizures find the root cause. With over 700,000 clinical exomes and genomes sequenced, there’s a reason GeneDx is the go-to lab when providers need diagnoses for children with epilepsy.

Our database is unmatched.
