Some missense gain-of-function mutations in the CACNA1C gene, encoding calcium channel CaV1.2, cause a life-threatening form of long QT syndrome (LQTS) named Timothy syndrome with currently no clinically effective therapeutics. Here we report that pharmacological targeting of sigma non-opioid intracellular receptor 1 (SIGMAR1) can restore electrophysiological function in induced pluripotent stem cell (iPSC)-derived cardiomyocytes generated… Continue reading Sigma non-opioid receptor 1 is a potential therapeutic target for long QT syndrome
