DESCRIPTION (provided by applicant): Newborn screening (NBS) is an essential public health program in all 50 states. The falling cost of whole genome/ exome sequencing provides an opportunity to ask whether whole genome analysis (WGA) might serve as a method of cost-effective newborn screening for any and every condition. We will address certain critical questions raised by the application of this technology to NBS. We will use Whole Exome Sequencing (WES) as a cost-effective method of WGA in 1620 newborn blood spots that are linked to the clinical data of the newborns. We will then test WES as a NBS Tool for metabolic and immunological disorders. These data will be used to 1) compare the sensitivity and specificity of mutation data with biochemical testing, 2) identify gene variants that predict which children with certain metabolic disorders are at greater risk for metabolic decompensation, 3) identify mutations in genes responsible for those primary immunodeficiencies that are not detected by the current T-Cell receptor excision circle assay used for severe combined immunodeficiency screening, and 4) scan 9 genes for variants that are clinically important for drug metabolism and would be typical "secondary findings" if WES were to be used as a NBS method. We will also develop a participant protection framework for conducting WGA during the neonatal period, determine the views, perspectives, and value preferences of key stakeholders about using WGA for NBS, collaborate with the UC Hastings Consortium on Law, Science and Health Policy, to identify the legal and constitutional issues for using WGA, and for incorporating PGx into NBS programs, and develop and disseminate policy recommendations for expanded NBS programs based on WGA.

描述（由申请人提供）：新生儿筛查（NBS）是所有50个州必不可少的公共卫生项目。全基因组/外显子组测序成本的下降提供了一个机会，即全基因组分析（WGA）是否可以作为一种具有成本效益的新生儿筛查方法，用于任何和每一种情况。我们将解决这项技术应用于NBS所带来的一些关键问题。我们将使用全外显子组测序（WES）作为一种具有成本效益的方法，对1620个与新生儿临床数据相关的新生儿血斑进行WGA分析。然后，我们将测试WES作为代谢和免疫紊乱的NBS工具。这些数据将用于1)比较突变数据与生化测试的敏感性和特异性，2)识别预测哪种疾病的基因变异
