PMID: 30795902
Loss-of-function mutations in Na1.7 cause congenital insensitivity to pain (CIP); this voltage-gated sodium channel is therefore a key target for analgesic drug development. Utilizing a multi-modal approach, we investigated how...

PMID: 25269517
Arterial spin labeling (ASL) sequences that incorporate multiple postlabeling delay (PLD) times allow estimation of when arterial blood signal arrives within a region of interest. Sequences that account for such...

PMID: 22365309
We identified a patient with severe inherited erythromelalgia secondary to an L858F mutation in the voltage-gated sodium channel Na(v)1.7. The patient reported severe ongoing foot pain, which was exquisitely sensitive...
