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. Segmental duplications in the human genome are selectively enriched for genes involved in immunity, although the phenotypic consequences for host defense are unknown. We surmised that a hot-spot for segmental duplications on human chromosome 17q might be relevant to immunity against infectious diseases such as HIV-1, since it encompasses two CC chemokine genes, CC chemokine ligand 3-like 1 (CCL3L1) and CCL4L1. We selected HIV infection as a model system in which to test our hypothesis that segmental duplications causing dosage effects of host defense genes are associated with phenotypic effects in vivo. To test this hypothesis, we determined the distribution of chemokine gene-containing segmental duplications in 1,064 humans from 57 populations and 83 chimp

该子项目是利用 NIH/NCRR 资助的中心拨款提供的资源的众多研究子项目之一。子项目和研究者 (PI) 可能已从另一个 NIH 来源获得主要资金，因此可以在其他 CRISP 条目中出现。列出的机构是中心的机构，不一定是研究者的机构。人类基因组中的片段重复选择性地富集了参与免疫的基因，尽管对宿主防御的表型影响尚不清楚。我们推测人类染色体 17q 上的片段重复热点可能与针对 HIV-1 等传染病的免疫力有关，因为它包含两个 CC 趋化因子基因：CC 趋化因子配体 3 样 1 (CCL3L1) 和 CCL4L1。我们选择 HIV 感染作为模型系统来测试我们的假设，即引起宿主防御基因剂量效应的节段重复与体内表型效应相关。为了检验这一假设，我们确定了来自 57 个种群的 1,064 名人类和 83 只黑猩猩中含有趋化因子基因的片段重复的分布
