摘要


Gaucher disease在中國人是一種罕見的自體隱性遺傳疾病,其中第二型會侵犯神經系統,並造成病人在嬰幼兒期死亡,診斷以臨床症狀及酵素分析爲主。最近,分子生物診斷學日新月異,利用聚合酶鏈反應的技術,我們發現一例中國人以同合子1448C突變基因型爲表現的第二型Gaucher disease,由於這樣的發現將對於Gaucher disease提供更可靠的診斷方式,並可應用於遺傳咨詢及産前診斷。

Gaucher disease is a rare autosonial recessive lysosomal storage disorder in Chinese. A mutation at nucleotide 1448C (T-to-C) of the glucocerebrosidase gene is described in type 2 Gaucher disease. This mutation creates a Bcn I site in a polymerase chain reaction (PCR) amplified fragment. This technique was applied to a Chinese infant with type 2 Gaucher disease, and homozygosity for 1448C mutation was proved. This new finding can make prenatal diagnosis and carrier detection possible in Chinese population with type 2 Gaucher disease.
