LQT1 is the most prevalent genetic form of LQTS accounting for approximately 50% of genotyped patients. Several different mutations have been reported (http:// pc4.fsm.it:81/cardmoc) and in vitro expression studies of mutated proteins suggested multiple biophysical consequences, all of them ultimately inducing a loss of function, with or without a dominant negative effect on the wildtype protein.[10] Homozygous or compound heterozygous mutations of KCNQ1 also cause Jervell and LangeNielsen form of LQTS (JLN1).[11]

KCNE1 (LQT5) mutations are rather infrequent accounting for approximately 2-3% of genotyped LQTS patients and they may cause both Romano-Ward (LQT5) and Jervell and Lange-Nielsen (JLN2) syndromes.[12,13]

Without all of the belts and artificial stabilizers of a machine, you also engage your core muscles, which are your body's natural stabilizers.
