確定癌癥的遺傳原因具有巨大的公共衛(wèi)生益處，從預防到早期發(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，但設計和分析問題仍然挑戰(zhàn)著當前基因發(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.
