"Important issues regarding the safety of I Kur blockers have been raised recently with the finding that loss-of-function mutations in KCNA5 are associated with familial AF. xref Because KCNA5 encodes the α subunit of the I Kur channel, these results suggest that a reduction in I Kur may predispose to the development of AF."

"Indeed, a loss-of-function mutation in KCNA5 associated with AF results in decreased ultrarapid delayed rectifier potassium current ( I Kur ), prolongation of the atrial action potential, and facilitates early afterdepolarizations. xref Recent discoveries have also revealed mechanisms by which mutations in sodium channels may influence AF susceptibility."
