The patient is also homozygous for the two minor variants rs4657139 and rs16847548 on the NOS1AP gene, associated with greater risk for cardiac arrest and sudden death in LQTS mutation carriers of the founder population. hiPSCs, obtained using four retroviruses encoding the reprogramming factors OCT4, SOX2, cMYC and KLF4, display pluripotent stem cell characteristics, and can be differentiated into spontaneously beating cardiomyocytes (hiPSC-CMs).

Methods To examine the effects of human LQTS-associated cav-3 mutations on HCN4-channel function, HEK293-cells were cotransfected with HCN4 and wild-type (WT) cav-3 or a LQTS-associated cav-3 mutant (T78M, A85T, S141R, or F97C).

The population also contain individuals with the Swedish long QT syndrome (LQTS1) founder mutation (<i>KCNQ1</i>/p.Y111C) which in homozygotes causes the Jervell & Lange Nielsen syndrome (JLNS) and hearing loss (HL).Aims of the study were to test whether the Swedish long QT founder mutation originated in an ancestral HFE family and if carriers had an increased risk for hemochromatosis (HH), a treatable disorder.
