摘要
目的探讨戈谢病的临床特点及诊断。方法回顾性分析1例经酶学及基因学诊断的戈谢病Ⅱ型患儿的临床特点、葡萄糖脑苷酯酶活性及基因突变类型。结果女孩,14个月,主要表现为肝脾大、眼球运动障碍、智力落后;骨髓片可见戈谢细胞;葡萄糖脑苷酯酶活性为0.3 nmol/(g·min),明显下降;壳三糖酶活力为87 317 nmol/(L·min),明显升高;分析葡萄糖脑苷脂酶基因,明确突变类型为M85T(c.371T>C)和R120W(c.475C>T)。结论戈谢病Ⅱ型主要表现为肝脾大,可伴有神经系统受损,葡萄糖脑苷脂酶活性及基因分析对诊断有重要意义。
Objectives To investigate the clinical characteristics and diagnosis of Gaucher disease. Methods The clinical features, enzyme activities and genetypes of an infant with Gaucher disease II were analyzed. Results The main clinical manifestations of the infant included hepatosplenomegaly, ocular dyscinesia and mental retardation. Gaucher＇s ceils could be seen in the bone marrow aspirates. Glucocerebrosidase activity was low （0.3 nmol/g/min）. Serum chitotriosidase activity was high （87317 nmol/L/min）. GBA mutations were M85T （c.371T〉C） and R120W （c.475C〉T）. Conlusions Main features of Gaucher disease II are hepatosplenomegaly with nerve system injury. Glucocerebrosidase activity and gene analysis are important for the diagnosis of Gaucher disease.
