  • Title: The molecular basis of long QT syndrome and prospects for therapy.
    Author: Wang Q, Bowles NE, Towbin JA.
    Journal: Mol Med Today; 1998 Sep; 4(9):382-8. PubMed ID: 9791861.
    Abstract:
    Long QT syndrome (LQT) is a cardiac disorder that causes sudden death from ventricular tachyarrhythmias, specifically torsade de pointes. Two types of LQT have been reported, autosomal-dominant LQT (Romano-Ward syndrome) and autosomal-recessive LQT (Jervell and Lange-Nielsen syndrome); Jervell and Lange-Nielsen syndrome is also associated with deafness. Four LQT genes have been identified for autosomal-dominant LQT: K+ channel genes KVLQT1 on chromosome 11p15.5, HERG on 7q35-36 and minK on 21q22, and the cardiac Na+ channel gene SCN5A on chromosome 3p21-24. Two genes, KVLQT1 and minK, have been identified for Jervell and Lange-Nielsen syndrome. Genetic testing and gene-specific therapies are available for some LQT patients.
