Long QT syndrome (LQTS) is a condition which affects repolarization of the heart after a heartbeat. This results in an increased risk of an irregular heartbeat which can result in palpitations, fainting, drowning, or sudden death. These episodes can be triggered by exercise or stress. Other associated symptoms may include hearing loss.. Long QT syndrome may be present at birth or develop later. Le syndrome de Brugada est une maladie génétique rare caractérisée par un sus-décalage du segment ST au niveau des dérivations précordiales droites V1, V2 et V3, et un aspect de bloc de branche droit à l'électrocardiogramme associés à un risque élevé d'arythmie ventriculaire pouvant entraîner syncope et mort subite, sur un cœur structurellement sain. Westenskow et al. () analyzed the KCNQ1, KCNH2, SCN5A, KCNE1, and KCNE2 genes in probands with long QT syndrome and identified 19 with biallelic mutations in LQTS genes, of whom 18 were either compound (monogenic) or double (digenic) heterozygotes and 1 was a homozygote. They also identified 1 patient who had triallelic digenic mutations (see ).
