腫瘤靶向治療基因檢測臨床應(yīng)用結(jié)果

佳學基因介紹了作為英國基因檢測網(wǎng)絡(luò) (UKGTN) 的一部分提供 NF1 基因檢測，診斷性突變檢測服務(wù)的經(jīng)驗。在 2 年期間，共有 169 名懷疑患有 I 型神經(jīng)纖維瘤病 (NF1) 的無關(guān)個體被三甲醫(yī)院醫(yī)生介紹進行 NF1 診斷性基因檢測、基因測試。對整個 NF1 編碼區(qū)和側(cè)翼剪接位點進行了突變分析，包括使用 FISH、dHPLC 和 MLPA 的組合。在 109 例 (64%) 病例中發(fā)現(xiàn)了可能引起疾病的突變。這些包括 88 種不同的序列改變，其中 57 種是新的。在轉(zhuǎn)診的169例中，有102例臨床資料高效，其中78例符合NIH對NF1的診斷標準。在這個更明確的 NF1 患者隊列中，在 61 人（78%）中發(fā)現(xiàn)了 NF1 突變，顯示了臨床選擇對整體測試敏感性的重要性，并突出了在日常服務(wù)檢查中全面收集臨床數(shù)據(jù)的問題。隨著突變檢測技術(shù)的進步，促進對 NF1 基因的所有編碼區(qū)和側(cè)翼非編碼區(qū)的直接測序，討論了為未來檢測 NF1 開發(fā)一種更具成本效益、快速和靈敏的診斷測試。

腫瘤發(fā)生與反復轉(zhuǎn)移國際數(shù)據(jù)庫描述：

Our experience of providing an NF1 gene diagnostic mutation detection service as part of the U.K. Genetic Testing Network (UKGTN) is presented. A total of 169 unrelated individuals suspected of having neurofibromatosis type I (NF1) were referred for NF1 diagnostic testing over a 2 year period. Mutation analysis of the entire NF1 coding region and the flanking splice sites was carried out, and included the use of a combination of FISH, dHPLC and MLPA. Possible disease causing mutations were identified in 109 (64%) cases. These comprised 88 different sequence alterations, of which 57 were novel. Out of the 169 cases referred, there were 102 patients with reliable clinical data, of whom 78 satisfied the NIH diagnostic criteria for NF1. Within this better defined cohort of NF1 patients, NF1 mutations were identified in 61 individuals (78%), showing the importance of clinical selection on overall test sensitivity, and highlighting the problem of full clinical data collection in the audit of routine services. As mutation detection technologies advance, facilitating direct sequencing of all coding and flanking non-coding regions of the NF1 gene, the development of an even more cost-effective, quick and sensitive diagnostic test for future testing of NF1 is discussed.
