Classical Trigeminal Neuralgia and Sodium Channel Mutations

Trigeminal Neuralgia Clinical Trial

Official title: Classical Trigeminal Neuralgia and Sodium Channel Mutations

Status Completed

Clinical Trial Summary

The most common cause of trigeminal neuralgia is considered to be a neurovascular contact. However, this etiological factor only seem to be present in half of the patient group. Thus the etiology of the other half is unknown.

Gain-of function genetic mutations in voltage gated sodium channels have been hypothesized as playing a role in the etiology of trigeminal neuralgia but it has yet to be confirmed. In recent years gain-of-function mutations have been identified as a causative factor in other pain-diseases presenting with trigeminal neuralgia phenotypic similarities.

Clinical Trial Description

The aim of this study was to indentify VGSC gene mutations, specifically SCN9A, SCN10A and SCN11A genes, in a group of well characterized trigeminal neuralgia patients.

Setting: The study will be conducted at The Danish Headache Center, Rigshospitalet - Glostrup, Denmark (inclusion of patients and written Informed Consent, patient interview, phenotyping/diagnosis, neurological examination, blood sample.
