Clinica Chimica Acta:α-Galactosidase / lysoGb3比作为诊断Fabry病女性的一个潜在的标记?

2020-02-06 MedSci MedSci原创

法布里病(Fabrys disease)即血管角质瘤综合征或安德森-法布 里病 (FD [MIM:301500])是一种GLA基因突变引起的x连锁溶酶体储存障碍。其产物溶酶体酶α-半乳糖苷酶A(α-GalA)的活性不足会导致糖鞘脂在多个器官的细胞中过度积累。

法布里病(Fabrys disease)血管角质瘤综合征或安德森-法布 里病 (FD [MIM:301500])是一种GLA基因突变引起的x连锁溶酶体储存障碍。其产物溶酶体酶α-半乳糖苷酶Aα-GalA)的活性不足会导致糖鞘脂在多个器官的细胞中过度积累。globotriaosylsphingosine (lysoGb3)被认为是GLA基因发生致病突变的女性更敏感的诊断性生物标志物。因此,本研究的目的是提高女性FD的生化诊断效率。

在这里,我们使用干血斑(DBS)作为测试样品,报告α-GalA / lysoGb3比值作为诊断女性FD的新生化标准。 在将我们的35名女性患者与对照组(n = 140)区分开来时,显示出100%的敏感性。 而单独测量α-GalAlysoGb3分别显示8.6%和74.4%。

因此,利用DBSα-GalA活性与lysoGb3浓度之比的新方法可能为鉴定FD女性提供更准确的筛查工具。
