Abstract
Paroxysmal extreme pain disorder is an autosomal dominant disorder caused by mutation of the SCN9A gene. In most cases, the pain is relieved by carbamazepine. We report on a novel SCN9A mutation associated with carbamazepine-resistant. The proband was a 7-month-old child who suffered from typical attacks from birth onwards. Sequencing of SCN9A revealed a heterozygous c.4880T>G substitution. Identification of this novel mutation and characterization of the associated carbamazepine-resistant phenotype may facilitate diagnosis and drug development.
