The symptoms of a myopathy permanently affecting limb girdle muscles are reported in a 31-year-old woman who has been presenting an exertional muscle pain syndrome with myoglobinuria for 20 years. Investigations revealed a slightly decreased utilization of glycogen in muscle, while its storage affected only rare type 2 fibers. Active phosphorylase was undetectable and phosphorylase b kinase activity was clearly decreased in muscle cells, but normal in erythocytes, lymphocytes and cultured fibroblasts.
一名31岁女性报告了永久性影响肢带肌的肌病症状，该患者出现运动性肌肉疼痛综合征伴肌红蛋白尿已有20年。检查发现肌肉中糖原利用率略有下降，而其储存仅影响罕见的2型纤维。在肌肉细胞中未检测到活性磷酸化酶，磷酸化酶b激酶活性明显降低，但在红细胞、淋巴细胞和培养的成纤维细胞中正常。
