GENETICS OF GROWTH FAILURE IN PEDIATRIC INFLAMMATORY BOWEL DISEASE

这个子项目是利用由NIH/NCRR资助的中心拨款提供的资源的许多研究子项目之一。子项目和调查员(PI)可能从另一个NIH来源获得了主要资金，因此可能会出现在其他CRISE条目中。列出的机构是针对中心的，而不一定是针对调查员的机构。我们假设，儿科炎症性肠病(IBD)生长失败的“前模式”过程是由遗传因素决定的。与生长和食欲调节、免疫反应和应激反应相互作用的基因，以及身材矮小的基因，是IBD相关生长失败的功能候选基因。我们的具体目的是探索与直线生长相关的表型特征与候选基因座变异的关系，以阐明IBD儿童生长障碍的遗传学基础。阐明IBD生长障碍的遗传基础可能提供新的治疗方法，或有助于确定为什么对现有营养治疗或药物的反应是不同的。早期干预方法也是可能的，最终可能会有更多知情的遗传咨询来指导受影响的亲属做出治疗决定。这项研究是由儿童医院炎症性肠病中心和麻省理工学院基因组研究中心合作进行的。这项描述性研究也将作为计划中的IBD遗传学研究联盟研究的试点。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. We hypothesize that the "pre-patterned" course of growth failure in pediatric inflammatory bowel disease (IBD) is determined by genetic factors. Genes interacting with growth and appetite regulation, immune responses, and stress responses, as well as the short-stature genes are functional candidates for IBD-related growth failure. Our specific aim is to explore the association of phenotypic characteristics related to linear growth with variations at candidate genetic loci, in order to elucidate the genetic basis for growth failure in children with IBD. Elucidating the genetic basis for growth failure in IBD might provide novel therapeutic approaches, or help define why reponse to available nutritional treatment or medication is heterogeneous. Early intervention approachses might also be possible, and more informed genetic counseling might ultimately be available to guide affected kindred in therapeutic decisions. This study is a collaboration of the Center for Inflammatory Bowel Disease at the Children's Hospital and the MIT Center for Genome Research. This descriptive study will also serve as a pilot for a planned IBD Genetics Research Consortium study.
