人體基因檢測需要多少錢—比較

開會學(xué)習(xí)基因?qū)嶒炇胰藛T知識更新《腫瘤靶向藥物選擇的基因突變標準》,了解到《J Natl Cancer Inst Monogr》在. 1999;(26):1-16.發(fā)表了一篇題目為《癌癥易感基因的發(fā)現(xiàn)：研究設(shè)計、分析方法和技術(shù)趨勢》腫瘤靶向藥物治療基因檢測臨床研究文章。該研究由D J Schaid, K Buetow, D E Weeks, E Wijsman, S W Guo, J Ott, C Dahl等完成。促進了腫瘤風(fēng)險基因檢測項目設(shè)計的全面性與正確性，進一步強調(diào)了基因信息檢測與分析在除低癌癥發(fā)病率中的重要性。

確定癌癥的遺傳原因具有巨大的公共衛(wèi)生益處，從預(yù)防到早期發(fā)現(xiàn)和治療疾病。盡管已經(jīng)成功鑒定了許多癌癥易感基因，但設(shè)計和分析問題仍然挑戰(zhàn)著當(dāng)前基因發(fā)現(xiàn)的范式。一些例子是癌癥表型的定義和測量、中間終點的使用、樣本的選擇（例如，受影響的相對對與大的擴展譜系）、分析基因解碼基因檢測的研究方法的選擇[例如，幾率的參數(shù)對數(shù) (LOD) score 基因解碼基因檢測的研究方法與無模型基因解碼基因檢測的研究方法]，以及基因-環(huán)境相互作用對連鎖分析的影響。此外，基于傳統(tǒng)病例對照研究設(shè)計或基于家庭的對照的關(guān)聯(lián)基因解碼基因檢測的研究方法是評估候選基因或篩選連鎖不平衡的流行選擇。賊后，基因發(fā)現(xiàn)的研究設(shè)計和分析基因解碼基因檢測的研究方法在一定程度上取決于實驗室內(nèi)何種基因組技術(shù)是可行的。許多與基因發(fā)現(xiàn)相關(guān)的主要問題，以及將影響基因發(fā)現(xiàn)的基因組技術(shù)趨勢，都從其優(yōu)缺點的角度進行了討論，指出了需要進一步開展工作的領(lǐng)域。

腫瘤發(fā)生與反復(fù)轉(zhuǎn)移國際數(shù)據(jù)庫描述：

Determining the genetic causes of cancers has immense public health benefits, ranging from prevention to earlier detection and treatment of disease. Although a number of cancer susceptibility genes have been successfully identified, design and analytic issues remain that challenge the current paradigm of gene discovery. Some examples are the definition and measurement of cancer phenotype, the use of intermediate end points, the choice of sample (e.g., affected relative pairs versus large extended pedigrees), the choice of analytic method [e.g., parametric logarithm of the odds (LOD) score method versus model-free methods], and the influence of gene-environment interaction on linkage analysis. Furthermore, association methods, based on either the traditional case-control study design or family-based controls, are popular choices to evaluate candidate genes or screen for linkage disequilibrium. Finally, the study design and analytic methods for gene discovery are determined to some extent by what genomic technology is feasible within the laboratory. Many of the main issues related to gene discovery, as well as trends in genomic technology that will impact on gene discovery, are discussed from the perspective of their strengths and weaknesses, pointing to areas in need of further work.
