DESCRIPTION (provided by applicant): The Cooperative Family Registry for Colorectal Cancer Studies (Colon CFR) is an NCI-supported consortium dedicated to the establishment of a comprehensive collaborative infrastructure for interdisciplinary studies in the genetics and genetic epidemiology of colorectal cancer. The cooperating institutions are collecting epidemiological information and laboratory specimens from families who represent the continuum of risk for colorectal cancer. A major area of etiological research to which the Colon CFR is committed is candidate gene association studies, where we plan to target selected "pathways", rather than focusing on isolated genes. This application, along with a parallel application submitted by Dr. John Potter, is meant to initiate the Colon CFR research on candidate genes. The Colon CFR has identified three pathways with which to start: folate metabolism and vitamin D/calcium, which are addressed in this application, and the NSAID pathway, which is addressed in Dr. Potter's application. For this application, we have the following specific aims: Folate. Conduct a family-based case-control association study of selected genes that are involved in the metabolism of folate. Our current list of genes of interest includes: serine hydroxymethyltransferase (SHMT1), mehylenetetrahydrofolate reductase (MTHFR), methionine synthase (MTR), methionine synthase reductase (MTRR), thymidylate synthase (TYMS or TS), S-adenosylhomocysteine hydrolase (AHCY or SAHH), ADA (adenosine deaminase), methionine adenosyl transferase 2A (MAT2A), folate receptor (FOLR1), reduced folate carrier (RFC1 or SLC19A1), S-adenosylmethionine decarboxylase (AMD1), gastric instrinsic factor (GIF), transcobalamin II (TCII), intrinsic factor cobalamin receptor (IFCR), and alcohol dehydrogenase 3 (ADH3). Vitamin D and Calcium. Conduct a family-based case-control association study of selected genes that are involved in the metabolism of vitamin D and calcium. Our current list of genes includes: vitamin D receptor (VDR), retinoid X receptor (RXR), vitamin D binding protein (DBF), calcium sensing receptor (CaSR), and the ileal sodium-dependent bile acid transporter (SLC10A2). Genotyping will primarily involve SNP-based haplotypes. For both pathways, analyses of gene-gene and gene-environment interactions will be included as appropriate.

描述（由申请人提供）：结直肠癌研究（COLON CFR）的合作家庭注册表是一个由NCI支持的财团，致力于在遗传学和大肠癌遗传学流行病学中建立跨学科研究的全面协作基础设施。合作机构正在从代表结直肠癌风险的家庭中收集流行病学信息和实验室标本。结肠CFR致力于的病因研究的一个主要领域是候选基因关联研究，我们计划针对选定的“途径”，而不是专注于孤立的基因。该应用程序以及John Potter博士提交的并行申请旨在启动有关候选基因的CFR研究。结肠CFR已经确定了三种开始的途径：在本应用中解决的叶酸代谢和维生素D/钙，以及在Potter博士的应用中解决的NSAID途径。对于此应用，我们有以下特定目标：叶酸。对参与叶酸代谢的选定基因进行基于家庭的病例对照关联研究。 Our current list of genes of interest includes: serine hydroxymethyltransferase (SHMT1), mehylenetetrahydrofolate reductase (MTHFR), methionine synthase (MTR), methionine synthase reductase (MTRR), thymidylate synthase (TYMS or TS), S-adenosylhomocysteine hydrolase (AHCY or SAHH), ADA (adenosine deaminase), methionine adenosyl transferase 2A (MAT2A), folate receptor (FOLR1), reduced folate carrier (RFC1 or SLC19A1), S-adenosylmethionine decarboxylase (AMD1), gastric instrinsic factor (GIF), transcobalamin II (TCII), intrinsic factor cobalamin receptor （IFCR）和酒精脱氢酶3（ADH3）。维生素D和钙。对与维生素D和钙的代谢有关的选定基因进行基于家庭的病例对照关联研究。我们当前的基因清单包括：维生素D受体（VDR），类视黄素X受体（RXR），维生素D结合蛋白（DBF），钙传感受体（CASR）和依赖钠依赖钠依赖的胆汁酸转运蛋白（SLC10A2）。基因分型将主要涉及基于SNP的单倍型。对于这两种途径，将适当地包括对基因基因和基因环境相互作用的分析。
