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）：结直肠癌研究合作家族登记处 (Colon CFR) 是一个由 NCI 支持的联盟，致力于为结直肠癌遗传学和遗传流行病学的跨学科研究建立全面的合作基础设施。合作机构正在从代表结直肠癌风险连续体的家庭收集流行病学信息和实验室标本。 Colon CFR 致力于病因学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”，而不是关注孤立的基因。该申请以及 John Potter 博士提交的并行申请旨在启动对候选基因的结肠 CFR 研究。结肠 CFR 已确定了三种启动途径：叶酸代谢和维生素 D/钙（本申请中对此进行了阐述）以及 NSAID 途径（在 Potter 博士的申请中进行了阐述）。对于此应用，我们有以下具体目标：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。我们目前感兴趣的基因列表包括：丝氨酸羟甲基转移酶 (SHMT1)、亚甲基四氢叶酸还原酶 (MTHFR)、甲硫氨酸合酶 (MTR)、甲硫氨酸合酶还原酶 (MTRR)、胸苷酸合酶（TYMS 或 TS）、S-腺苷同型半胱氨酸水解酶（AHCY 或 SAHH） )、ADA（腺苷脱氨酶）、甲硫氨酸腺苷转移酶 2A (MAT2A)、叶酸受体 (FOLR1)、还原叶酸载体（RFC1 或 SLC19A1）、S-腺苷甲硫氨酸脱羧酶 (AMD1)、胃内因子 (GIF)、转钴胺素 II (TCII)、内因子钴胺素受体 (IFCR) ) 和乙醇脱氢酶 3 (ADH3)。维生素 D 和钙。对参与维生素 D 和钙代谢的选定基因进行基于家庭的病例对照关联研究。我们目前的基因列表包括：维生素 D 受体 (VDR)、类视黄醇 X 受体 (RXR)、维生素 D 结合蛋白 (DBF)、钙传感受体 (CaSR) 和回肠钠依赖性胆汁酸转运蛋白 (SLC10A2)。基因分型主要涉及基于 SNP 的单倍型。对于这两种途径，将酌情包括基因-基因和基因-环境相互作用的分析。
