Abstract

Синдром ламкої Х-хромосоми (Мартина-Белла) — найрозповсюдженіша форма розумової відсталості з Х-зчепленим типом успадкування з неповною пенетрантністю. Частота розповсюдження складає близько 1 на 1500 чоловіків та 1 на 2500 жінок. У даному огляді наведено сучасні дані про структуру гена FMR1, природу динамічних мутацій, пов'язаних з експансією інтрагенних CGG-повторів, а також інших типів мутацій у цьому гені.
