Bridging Personal and Population in Excitability Diseases: Will Studies of Rare Diseases Bring Generalizable Mechanisms From Monogenic Channelopathies?

This study developed a new method to analyze Cantú syndrome mutations in KATP channels, finding that while Kir6.1 mutations increase sensitivity to potassium channel openers, SUR2B mutations show reduced sensitivity, but both result in marked hyperpolarization compared to wild-type channels under basal conditions.

This study identified heterozygous mutations in the ABCC9 gene as the genetic basis of Cantú syndrome, suggesting the syndrome as a new member of potassium channelopathies.

This study confirms that zebrafish engineered with Cantú Syndrome mutations in ABCC9 and KCNJ8 genes exhibit gain-of-function characteristics in their cardiovascular KATP channels, similar to mammalian counterparts.

This study reports that mutations in the SUR2 gene are linked to Cantu syndrome, highlighting the role of KATP channels in cardiovascular health and potential new therapies.

This editorial reviews the roles and therapeutic potential of inward rectifying K+ channels in various physiological processes, highlighting their importance in health and disease but provides no new experimental results.
