| 中文摘要 | 背景 : McLeod 症候群是一種位於性聯 X 染色體上 XK 基因發生突變的罕見隱性遺傳多系統疾病,造成 XK 蛋白異常,導致 kx 抗原缺少。輸血醫學上,若病人未診斷為 McLeod 症候群,輸注一般血球製品後, 很容易產生 Kx 或 Kx+Km 的抗體,會導致病患需輸血時無法找到交叉相合的血液製品,因此建議有類似 McLeod 症候群症狀之患者進行基因檢測,鑑別是否發生 XK 基因突變,以便於臨床診斷及後續患者輸血 安全。 結果 : 實驗室檢查結果發現病人的紅血球 k 抗原表現降低,血液抹片檢查有棘狀紅血球增多的現象,基 因檢測發現新的基因缺失(c.435delC)。 |
| 英文摘要 | Background: McLeod syndrome is an X-linked recessive multisystem disorder resulted from the mutation in XK gene and produced abnormal XK proteins causing weakened k antigen expression. In transfusion medicine, if the patient has not been diagnosed with McLeod syndrome, it’s highly possible to develop anti-Kx or anti-Kx+Km antibody after receiving blood cell transfusion. It would make it difficult to issue compatible blood products for McLeod syndrome patients. Therefore, McLeod syndrome potential patients are suggested doing the genetic examination to diagnose possible XK gene mutation. This will make it easier to do clinical diagnosis and transfusions safety in the future. Result: The laboratory examination showed that weakened k antigen expression and acanthocytosis were demonstrated and found a novel mutation in the XK gene. |
