Po-714-04 high prevalence of neurodevelopmental disorders in pediatric long qt syndrome patients

Long QT Syndrome (LQTS) is a familial ion channelopathy associated with a structurally normal heart and risk of sudden cardiac death. Most cases are associated with variants in KCNQ1 and KCNH2 genes. Ion channel variants have been implicated in neurodevelopmental disorders (NDDs), yet the link between LQTS and NDDs in children has not been well characterized.
