DESCRIPTION: (Applicant's Description) Inherited predispositions to specific cancers due to high penetrance alleles of genes such as APC and BRCA1 account for only a small percentage of our populations cancer burden. Genetic epidemiological evidence suggests, however, that a much higher percentage of individuals may be at risk due to the inheritance of alleles, or combinations of alleles, that individually show only a relatively low cancer penetrance. This makes it difficult to analyze the associated patterns of inheritance, localize the loci and identify the specific genes involved. Large sample populations are now required to map and identify these genes. We propose establishing a consortium consisting of the Universities of Colorado, New Mexico and Utah whose primary purpose will be to enroll a study population and create an infrastructure to support this next generation of exploration of the genetics of cancer. A population-based approach is needed to understand the population significance of future findings. State cancer registries provide an appropriate avenue of ascertainment. It is also important to develop a study population enriched for predisposed individuals. Our approach, therefore, is to ascertain individuals with one or more relatives who have been diagnosed with the specific cancer. Specifically, we propose initially to contact each individual diagnosed with breast, prostate, or colorectal cancer in calendar 1998 and 1999 and determine: 1) whether they are willing to participate and 2) have first-degree relatives affected with their same cancer. If so, they will be recontacted and asked to provide more detailed information regarding family history, as well as demographic and epidemiologic information. Selected index cases will be requested to complete questionnaires, which will include the names of their first-degree relatives and their permission to contact these relatives. The first-degree relatives will then be contacted and invited to enroll as members of the Cancer Genetics Network. This approach will create a study population of family members who have had cancer and who are at risk for cancer. We will also offer enrollment to appropriate individuals who have already contacted our high-risk clinics or are enrolled in ongoing clinical protocols of familial cancer; for example, Colorado will extend their current research interests by collecting lung cases. In addition, we will establish or enhance clinical and laboratory core facilities, as well as the necessary capabilities in genetic counseling, informatics and database management. As study groups are enrolled, DNA samples may be collected and pilot projects initiated; these include sib-pair studies and candidate-gene analysis funded by the Huntsman Cancer Institute and the University of Colorado Cancer Center.

描述：（申请人的描述）遗传倾向， 由于基因的高多态性等位基因如APC和 BRCA 1仅占我们人口癌症负担的一小部分。 然而，遗传流行病学证据表明， 由于等位基因的遗传， 或等位基因的组合，单独显示出相对较低的 癌细胞浸润。 这使得很难分析相关的 遗传模式，定位基因座并识别特定基因 涉案 现在需要大样本人群来绘制和识别 这些基因。 我们建议成立一个财团， 科罗拉多、新墨西哥州和犹他州的大学，其主要目的是 招募研究人群并建立基础设施来支持这一点 下一代癌症遗传学的探索。 一 需要一种基于人口的方法来了解人口 未来发现的意义。 国家癌症登记处提供了 适当的确认途径。 同样重要的是， 研究人群富集了易感个体。 我们的方法， 因此，是确定个人与一个或多个亲属谁有 被诊断出患有特定的癌症。 具体来说，我们建议首先 联系每一个被诊断患有乳腺癌、前列腺癌或结肠直肠癌的人， 癌症在日历1998年和1999年，并确定：1）他们是否愿意 参与和2）有一级亲属受其影响， 癌 如果是这样，我们将重新联系他们并要求他们提供更详细的信息 关于家族史的信息，以及人口统计学和 流行病学信息。 选定的索引病例将被要求 完整的问卷，其中将包括他们的第一学位的名字 亲属及其联系这些亲属的许可。 的一级 然后将与亲属联系，并邀请他们登记成为 癌症遗传学网络。 这种方法将创建一个研究人群， 患有癌症和有患癌症风险的家庭成员。 我们将 还向已经联系过的适当个人提供注册 我们的高风险诊所或正在进行的临床方案， 家族性癌症;例如，科罗拉多将扩展他们目前的研究 通过收集肺部病例的兴趣。 此外，我们将建立或 加强临床和实验室核心设施，以及必要的 遗传咨询、信息学和数据库管理能力。 作为 研究小组被招募，DNA样本可能被收集，试点项目 启动;其中包括同胞对研究和候选基因分析资助 亨斯迈癌症研究所和科罗拉多癌症大学 中心
