"Type 3 LQTS (LQT3) is associated with mutations in the SCN5A gene, which codes for the Na + voltage-gated channel. xref "

"SCN5A mutations associated with long QT syndrome type 3 (LQT3) lead to enhanced late sodium current and consequent action potential (AP) prolongation."

sparser
"Long QT syndrome type 3 (LQT3) is associated with genetic modifications of the Scn5a gene, which interfere with Na + channel inactivation and lead to persistent, arrhythmogenic late Na + currents ( xref )."

"However, sinus node dysfunction has also been reported in patients with gain-of-function SCN5A mutations associated with long QT syndrome type 3 (LQT3) in apparent overlap with the previous examples ( xref )."
