Генетические особенности у детей с подозрением на синдром Альпорта: Результаты полноэкзомного секвенирования
Ключевые слова:
синдром Альпорта, Х-сцепленный синдром Альпорта, полноэкзомное секвенирование, корреляция генотипа и фенотипа, нарушения сплайсингаАннотация
Введение. Синдром Альпорта является редким мультисистемным заболеванием, вызванным мутациями в генах COL4A3, COL4A4, COL4A5. Актуальность изучения синдрома Альпорта обусловлена его высокой частотой среди наследственных заболеваний почек, чрезвычайной генетической и фенотипической гетерогенностью, сложностью интерпретации клинических и генетических методов диагностики, наличием значимых популяционных различий в частоте и спектре специфичных мутаций.
Целью настоящего исследования является анализ данных полноэкзомного секвенирования у пациентов с клинико-лабораторным подозрением на синдром Альпорта для характеристики спектра выявляемых генетических вариантов, вызываемых данное заболевание
Методы. Выделение геномной ДНК из образцов крови от пациентов с предполагаемым синдромом Альпорта. Проведено полноэкзомное секвенирование образцов, а также биоинформатическая и статистическая обработка данных секвенирования.
Результаты. Выявлена ранее неописанная мутация в интронной области гена COL4A5 с.1588-2A>G, вероятно ассоциированная с синдромом Альпорта.
Выводы. Исследование подчеркивает значимость генетических исследований синдрома Альпорта, и важность изучение интронных областей генов COL4A3, COL4A4, COL4A5.
