В статье представлены результаты 5-летнего наблюдения двух сестер-близнецов с субклиническим первичным гипотиреозом, у которых по данным молекулярно-генетического обследования выявлена гомозиготная мутация в гене рецептора ТТГ (p.R450H). Обсуждаются показания к заместительной терапии левотироксином.

Two female dizygotic twins with subclinical primary hypothyroidism due to homozygous p.R450H mutation in TSHR gene are presented. A 5-year follow-up in both cases showed no progression of thyroid dysfunction. Indications for levothyroxine replacement in subclinical hypothyroidism are discussed.
