Проведено фармакогенетичне дослідження 83 дітей з фармакорезистентними епілепсіями віком від 11 місяців до 18 років. За допомогою алель-специфічної полімеразної ланцюгової реакції (ПЛР), визначали поліморфізми гена CYP2C19 (CYP2C19*1, CYP2C19*2). Алель CYP2C19*2 нами зафіксований у 33 (39,76 %) пацієнтів. У 5-х (15,15 %) з них носійство генотипу CYP2C19*2 виявлено в комбінації з іншими поліморфізмами генів (СYP2C9*2, CYP2C9*3, CYP3A4*1B). Поліморфізм CYP2C19*2 в обстежуваних нами пацієнтів зустрічався достовірно частіше ніж в українських та інших європейських популяціях.Посилання
