介紹

罕見病並不罕見的原因在於,雖然每種罕見病單獨來看影響的人數較少,但總體上這些疾病影響的人數卻非常可觀。以下是一些原因:

  • 罕見疾病數量眾多:目前已知的罕見疾病超過8,000種。每一種罕見疾病可能只影響少數人,但當所有這些罕見疾病的患者加在一起時,總數變得相當巨大。

  • 總體患病率高:雖然單一的罕見病可能只影響不到200,000人(在美國的標準),但所有罕見疾病加起來估計影響了大約6-8%的人口。這意味著全球有數百萬人患有罕見病

  • 基因因素:許多罕見疾病是由基因突變引起的。隨著基因研究的進展,發現了許多罕見的遺傳突變和疾病。隨著越來越多的罕見基因疾病被發現,這些疾病的總體影響變得更加明顯。

  • 誤診和漏診:由於缺乏對罕見病的認識,許多罕見病可能被誤診或漏診。這可能導致這些疾病看起來比實際情況更罕見。隨著診斷工具的改進和認識的提高,更多的病例被識別出來。

  • 症狀和影響多樣化:罕見疾病的症狀和嚴重程度各不相同,可能影響不同的器官和系統。意味著罕見病對公共健康、醫療系統和受影響家庭有顯著的影響。


找出病因

早期診斷是治療孟德爾 (Mendelian) 遺傳病或單基因罕見疾病的關鍵

目前發現的遺傳病超過8000種,主要是單基因遺傳病(孟德爾遺傳病)。這些遺傳病影響全球數以百萬計的人

  • 使用通過臨床驗證的全基因組檢測(不是全基因測試),可有效檢測出遺傳病的病因

  • 全基因組檢測超過二萬個基因(基因組的 1.5%)和基因之間的致病突變區域(基因組的 98.5%),病人可以得到更準確的診斷結果

End Diagnostic Odyssey (終結漫長的診斷過程)

  • 對於經傳統的生化,少量基因或外顯子組基因檢測(全基因)和臨床分析都未能確認病因的患者來說,經過一次性全基因組檢測,患者可能會得到診斷,因為全基因組檢測的診斷成功率約為50%-65% (取決於疾病類型)

我們的醫療人員將重點關注受檢者的疾病狀態 (表型) 和相應致病基因的變異,增加診斷成功率

ACMG 建議的

偶然發現

由於全基因組檢測的全面性, 有可能會發現一些與主診症狀無關的遺傳變異

  • 這些在“偶然”中發現的遺傳變異可能與一些未被患者或醫生所預料的健康問題有關

ACMG (美國醫學遺傳學及基因組學學會) 就此發布了相關的指引。指引裡提及有多種遺傅基因變異已經被確定為“醫學上能够干預的”, 即遺傳變異所引起的疾病是有可能管理及預防的。

  • 其中包括了結直腸癌和乳腺癌, 心血管病 (其中有一部份與彩虹心臟檢測重複), 家族性高膽固醇血症和惡性高熱症等.

  • Rainbow Genomics 會對這些偶然在檢測中發現的基因變異, 提供患者是否需要解讀的選擇.


其他報告選擇

醫生或患者可以另外要求 -

  • 全基因組隱性疾病基因變異攜帶者報告 (Carrier Status Report)

  • 全基因組, 與您的個人健康有關的廣泛偶然基因變異發現報告
