About this trial

Epilepsy is a common condition which affects over 3 million people in the US. Patients with uncontrolled epilepsy have a lifetime risk of sudden unexpected death (SUDEP) of 35%, which is greatest in those under 40 years of age. The exact mechanisms and causes are not understood but can be due to underlying conditions which affect the heart and brain, which may lead to dangerous heart rhythms and death. Some of these conditions which affect heart and brain have an identifiable genetic cause. This study aims to identify known genetic causes of heart rhythm and sudden death related disorders in patients with epilepsy.

Eligibility criteria

Disqualifiers

Those who are unable to provide written consent.

Prisoners (vulnerable population)

Seizures secondary to ischemic events

Traumatic brain injury resulting in seizures

Trial population

Men and women diagnosed with epilepsy or seizures or unexplained syncope and blood relatives.

Trial outcomes

Primary outcomes

1

Using Next Generation Whole-Exome Sequencing, determine if an underlying genetic cardiac mutation is present in refractory epilepsy patients who are at highest risk of sudden death.

SUDEP-7 is a risk profiling tool, with a score ranging from 0-12. Generally, a score greater than or equal to 3 is considered high risk. The investigators will select participants with a family history of epilepsy, seizures, cardiac arrest, sudden death, drowning, syncope or arrhythmia, as this markedly increases genetic yield. Next Generation Whole-Exome Sequencing will be performed with a focus on known genes implicated in sudden unexpected death syndromes (channelopathies, cardiomyopathies and aortopathies) and autonomic control. Where relevant, blood-relatives may be invited for genomic 'trio' analyses.
