Myophosphorylase deficiency or McArdle's disease is rarely recognized in childhood. The onset is generally in adolescence or in adult age with exercise intolerance, muscle cramps and myoglobinuria. Two siblings of 6 and 2 years of age are described. The first patient showed early fatigue and both had elevated CK levels. Morphological and biochemical studies of muscle biopsies revealed a defect of myophosphorylase.
肌磷酸化酶缺乏症或麦卡德尔病在儿童期很少被识别。发病通常在青春期或成年期,表现为运动不耐受、肌肉痉挛和肌红蛋白尿。本文描述了两名分别为6岁和2岁的兄弟姐妹。首例患者表现出早期疲劳,两人的肌酸激酶(CK)水平均升高。肌肉活检的形态学和生化研究显示存在肌磷酸化酶缺陷。
