Исследование проведено на материале международного проекта HAPIEE в период с 2003 по 2005 г. и скрининга молодых людей 25–44 лет, выполненного в Новосибирске. Общая выборка мужчин составила 1 353 человека в возрасте от 25 до 69 лет. Из каждой возрастной подгруппы (25–29, 30–34, …, 65–69 лет) выбрано по 2–3 образца с наибольшими значениями QTc. Исследуемая группа состояла из 30 мужчин, которым в дальнейшем выполнено секвенирование панели генов. Поиск мутаций проведен в генах, ассоциированных с синдромом удлиненного интервала QT (LQTS): KCNQ1, KCNH2, SCN5A, KCNE1, KCNE2, KCNJ2, CACNA1, SCN4B, KCNJ5, ANK2, CAV3, SNTA1, AKAP9, CALM1 и CALM2.

The study was conducted on the material of the international project HAPIEE in the period from 2003 to 2005 and screening of young people aged 25–44, performed in Novosibirsk. The total sample of men was 1353 people aged 25 to 69 years. From each age subgroup (25–29, 30–34, ..., 65–69 years old) 2–3 samples with the highest QT values were selected . The study group consisted of 30 men who subsequently underwent sequencing of a panel of genes. The search for mutations was carried out in genes associated with long QT syndrome (LQTS): KCNQ1, KCNH2, SCN5A, KCNE1, KCNE2, KCNJ2, CACNA1, SCN4B, KCNJ5, ANK2, CAV3, SNTA1, AKAP9, CALM1 and CALM2.

In Caucasian men from the Novosibirsk population with borderline prolongation of the QT interval, probably causal substitutions in the LQTS genes – KCNH2 and KCNQ1, contributing to the prolongation of the QT interval, were found.
