项目摘要

Abstract The Plain populations (Amish and Mennonites) originated from founder populations with subsequent genetic bottlenecks and genetic drift; leading to a loss of diversity and an altered genetic disease burden. The Western PA Plain people are among the least genetically characterized Plain communities in the US. This application proposes to use Whole Exome Sequencing (WES) to identify novel genetic disorders in this population. Due to the Plain Populations loss of population genomic complexity, inbreeding, and sociologic isolation, many of the genetic disorders are inherited in autosomal recessive fashion due to homozygous mutations. This genetic makeup as well as the large families will facilitate WES analysis to find candidate variants that can potentially be pathogenic causes of diseases. A multitude of genetic diseases are characterized in the Plain population, and this proposed study will identify additional diseases, enabling a community-centric personalized medicine approach to care based on individual genetic risk. In addition, knowledge of genetic disorders originally developed through study of the Plain Populations, can subsequently be applied in the general population. The central hypothesis is that the Amish and Mennonite communities will allow the identification of novel genetic disorders/pathogenic variants of relevance to the Plain communities, and ultimately the general population. The following aims are proposed: (1) Identification of novel genetic disorders/ disease-causing variants in the Plain communities. The hypothesis is that genetics studies of the Western PA Plain people using WES will allow for continued characterization of novel genetic disorders/pathogenic variants that are relevant to both the Plain and general populations. (2) Performing functional studies for a novel genetic disorder causing dilated cardiomyopathy (DCM). The hypothesis is that the MTCL1 variant (c.82C>G;p.His28Asp) is pathogenic and MTCL1 gene mutations are novel cause of DCM. The candidate is firmly committed to a career in translational genomics research and its implications on the Plain and General populations. She has already worked within the Plain communities, proving her ability to connect with and perform research within these culturally distinct groups. These connections, and her research focus on translational research using WES as a diagnosis tool with functional studies when needed, have already led to the discovery of several mitochondrial disorders and an AK2 gene mutation as a cause of an immunodeficiency with a novel phenotype in the Amish. The primary sponsor is a world recognized expert in the field of Genetics with an outstanding track record of training and with a great working relationship with the candidate. The candidate has developed a comprehensive career development plan to improve her bioinformatics and WES analysis skills, and will learn to perform functional studies related to cardiomyopathy.

摘要平原人口（阿米什人和门诺派）起源于创始人人口，随后的遗传瓶颈和遗传漂变;导致多样性的丧失和遗传疾病负担的改变。西部 PA平原人是美国遗传特征最少的平原社区之一。本申请建议使用全外显子组测序（WES）来鉴定该人群中的新型遗传疾病。由于平原种群由于种群基因组复杂性的丧失、近亲繁殖和社会隔离，遗传性疾病由于纯合突变而以常染色体隐性方式遗传。这种遗传组成以及大家族将有助于WES分析，以找到可能被疾病的致病原因。许多遗传性疾病的特点是在平原人口，这项拟议中的研究将确定其他疾病，从而实现以社区为中心的个性化医疗基于个体遗传风险的护理方法。此外，遗传疾病的知识最初通过对平原人群的研究而开发的，随后可以应用于一般人群。的中心假设是，阿米什人和门诺派社区将允许识别新的遗传与平原社区相关的疾病/致病性变体，并最终与普通人群相关。的提出了以下目标：（1）在平原地区鉴定新的遗传性疾病/致病变体社区.假设是，使用WES的西PA平原人的遗传学研究将允许继续表征与普通和一般人群。(2)对一种新的遗传性疾病进行功能研究，心肌病（DCM）。假设MTCL 1变体（c.82C>G;p.His28Asp）是致病性的， MTCL 1基因突变是DCM的新病因。候选人坚定地致力于翻译事业基因组学研究及其对平原和普通人群的影响。她已经在平原社区，证明她有能力与这些文化上不同的社区建立联系并进行研究。组这些联系，以及她的研究重点是使用WES作为诊断工具的转化研究在需要时进行功能研究，已经导致发现了几种线粒体疾病，一种AK 2基因突变，是阿米什人中具有新表型的免疫缺陷的原因。主赞助商是世界公认的遗传学领域的专家，具有出色的培训记录，与候选人保持良好的工作关系。候选人已经发展了全面的职业生涯发展计划，以提高她的生物信息学和WES分析技能，并将学习执行功能与心肌病有关的研究。
