This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. Personalized medicine can offer patients drugs that are tailored to specific genetic profiles. Current pharmacogenomic testing, however, is limited by a lack of model systems which accurately represent the underlying individual genetic variation. We are developing non-human primate model systems that incorporate the genetic variation underlying complex, polygenic disease focusing primarily on afflictions of the nervous system. We identify naturally-occurring genetic variation in rhesus monkeys that functionally mimics variation in human orthologous genes. This offers the unique situation that not only is the underlying gene target highly similar to humans but the disease-causing mechanisms are similar as well. Our research has focused on identifying, cataloging, and assessing the functionality of rhesus monkey genetic variants with directly observable and measurable phenotypic and physiological traits paralleling those underlying human disorders. The overarching goal is to naturalistically model human genotype/phenotype relationships and pharmacogenomic response variance in a non-human primate model. We are identifying rhesus macaque cohorts that genetically and phenotypically emulate particular human populations, allowing us to elucidate the genetic interactions influencing disorder-related phenotypes and develop a preclinical platform for testing pharmacogenomic-informed drugs directly applicable to human personalized medicine. Alcoholism is a pharmacogenomic disease in which multiple genes each make modest contribution, and a detailed understanding of the polygenetic contributions to alcoholism can provide the basis for developing pharmacogenomics-based treatment strategies for alcohol-related problems. This research offers an unprecedented opportunity to accurately and specifically model polygenic disorders in a highly translational setting allowing for the development of the personalized drugs of the future.
