Заболевание имеет Х-сцепленное рецессивное наследование, обусловлено мутациями в гене PHKA2, локализованном на коротком плече хромосомы Х в регионе Хр22.13. Основные проявления болезни: задержка роста, увеличение размеров печени, эпизоды гипогликемии, кетоза натощак, повышение в  крови уровня холестерина, липопротеидов низкой плотности, триглицеридов, печеночных трансаминаз. Во многих случаях течение болезни может быть относительно легким, что затрудняет раннюю диагностику и своевременное назначение терапии. Приведены клинические наблюдения за двумя детьми из неродственных семей с одинаковой гомозиготной мутацией c.884G&gt;A (р.Arg295His, или R295H) в гене PHKA2. Подчеркнуты сходство и различия клинической симптоматики, представлены особенности ведения пациентов.</p></abstract><trans-abstract xml:lang="en"><p>IXa glycogenosis is the most common of the currently known 15 types of glycogenosis. The disease has X-linked recessive inheritance, is caused by mutations in  the PHKA2 gene localized on the short arm of X chromosome in  the Хр22.13 region. The main manifestations of the disease: stunted growth, increased liver size, episodes of hypoglycemia, fasting ketosis, increased blood levels of cholesterol, low-density lipoproteins, triglycerides, liver transaminases. In many cases, the course of the disease can be relatively mild, which complicates early diagnosis and the timely administration of therapy. Clinical observations of two children from unrelated families with the same homozygous c.884G&gt; A mutation (р.Arg295His, or R295H) in the PHKA2 gene are presented. The similarities and differences in clinical symptoms are emphasized, and the features of patient management are presented.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>гликогеноз типа IXa</kwd><kwd>задержка роста</kwd><kwd>гликемия</kwd><kwd>кетоз</kwd><kwd>холестерин</kwd><kwd>трансаминазы</kwd><kwd>мутация c.884G&gt;A гена PHKA2</kwd><kwd>диета</kwd><kwd>кукурузный крахмал</kwd></kwd-group><kwd-group xml:lang="en"><kwd>children</kwd><kwd>IXa glycogenosis</kwd><kwd>stunted growth</kwd><kwd>glycemia</kwd><kwd>ketosis</kwd><kwd>cholesterol</kwd><kwd>transaminases</kwd><kwd>c.884G&gt; A mutation of  the PHKA2 gene</kwd><kwd>diet</kwd><kwd>corn starch</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование проведено в рамках финансирования Гос-задания «Анализ клинико-генетического полиморфизма  инвалидизирующих моногенных заболеваний у детей для  прогнозирования их течения и определения молекулярных мишеней для оптимизации лечения»</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Строкова Т.В., Прохорова И.В., Сурков А.Г., Багаева М.Э., Павловская Е.В., Таран Н.Н. и др.
