PROJECT SUMMARY, Core C: MHC Genetic Typing Core Genetically well-characterized animal models are critical for the success of S/HIV research, including characterization for MHC genotype, known ancestry, and pedigree relationships. In particular, informative and accurate MHC genotyping is essential, due to the complexity of the MHC class I loci in macaques, and the influence of allele type on disease progression. The need for genetically well-characterized animal models for research must also be balanced against the need to preserve genetic diversity in animal colonies dedicated to supporting biomedical research. This is a requirement not only to ensure long-term colony health, but to ensure the relevance of experimental findings to human disease. The ONPRC is a leader in the development of many of the current recommended approaches and technologies used in genetic typing and management of NHP colonies. Thus, the aims of the Genetics Core for this project are to, 1) use state-of-the-art genetic testing to characterize all ONPRC Indian-origin rhesus macaques for MHC genotype, and 2) to maximize the genetic diversity of the ONPRC breeding colony while producing sufficient numbers of MHC-genotyped Indian-origin rhesus macaques to meet research needs. To achieve these aims, we will conduct MHC Class I genotyping of an additional 1,760 SPF4 Indian-origin rhesus macaques to support continued research, and will additionally develop new or improved approaches to the genetic management of these macaques. These innovations include the use of cost-effective genome-wide sparse sequencing to assess pedigree relationships, genetic diversity, and ancestry in a single, combined assay; the implementation of automated, periodic reporting aimed at summarizing genetic diversity for every breeding group in the colony; and improved algorithms for estimating the genetic value of individual animals by adding information on demographics, genotypes or phenotypes of interest, and animal assignment history.

项目摘要，核心 C：MHC 基因分型核心 遗传特征良好的动物模型对于 S/HIV 研究的成功至关重要，包括 MHC 基因型、已知血统和谱系关系的表征。特别是信息丰富且 由于猕猴中 MHC I 类基因座的复杂性，准确的 MHC 基因分型至关重要 等位基因类型对疾病进展的影响。需要具有良好遗传特征的动物模型 研究还必须与保护动物群体遗传多样性的需要相平衡 支持生物医学研究。这不仅是为了确保蜂群的长期健康，也是为了确保 实验结果与人类疾病的相关性。 ONPRC 是许多领域发展的领导者 目前推荐用于 NHP 基因分型和管理的方法和技术 殖民地。因此，该项目遗传学核心的目标是，1）使用最先进的基因测试来 表征所有 ONPRC 印度源恒河猴的 MHC 基因型，以及 2) 最大化遗传 ONPRC 繁殖群体的多样性，同时产生足够数量的 MHC 基因型印度起源 恒河猴以满足研究需要。为了实现这些目标，我们将进行 MHC I 类基因分型 另外 1,760 只 SPF4 印度原产恒河猴以支持持续研究，并将另外 开发新的或改进的方法来管理这些猕猴的遗传。这些创新包括 使用经济高效的全基因组稀疏测序来评估谱系关系、遗传多样性和 单一、组合检测中的血统；实施自动定期报告，旨在总结 群体中每个繁殖群体的遗传多样性；以及改进的估计遗传价值的算法 通过添加有关人口统计、感兴趣的基因型或表型以及动物的信息来分析个体动物 任务历史记录。
