# 1/2 Cell Type and Region-Specific Regulatory Networks in Human Brain Development and Disorders > **NIH NIH U01** · YALE UNIVERSITY · 2020 · $1,345,238 ## Abstract ABSTRACT Recent advances in genetics and genomics have identified hundreds of coding variants that increase risk for major neuropsychiatric disorders, such autism spectrum disorder. Work to clarify the contribution of non-coding variants is also underway and is expected to accelerate rapidly in the next few years. While these advances have considerably improved our understanding of the genetic landscape neuropsychiatric disorders, a deeper understanding of molecular pathophysiology is still missing. This knowledge gap is due to, in part, the heterogeneity of risk loci involved, their potential roles in regulating expression of a large number of genes, the pleiotropic nature of risk genes, and the high likelihood that neuropsychiatric disorders result from dysfunctional circuitry involving multiple cell types and brain regions, altogether making the identification of molecular and cellular mechanisms underlying a disease problematic, especially in the context of the protractive and complex nature of brain development. Therefore, the discovery and characterization of the full spectrum of functional genomic elements active in the human brain, as well as their activity/expression patterns across the spatiotemporal dimensions, is essential for clarifying when, where, and what cell types are relevant to the etiology and treatment of neuropsychiatric disorders. This is particularly so in the context of non-coding variants, which are difficult to annotate, yet potentially hold the promise of providing highly specific spatial, temporal, and cell type specific information. To address this knowledge gap and to continue our contributions to the PsychENCODE Consortium, we propose four specific aims that identify gene regulatory and cell type- specific mechanisms of human neurodevelopment. In Aim 1, we identify functional genomic elements across single cells (nuclei), cell types, regions and developmental time points of neurotypical human and macaque postmortem brains. In Aim 2, we map the spatio-temporal proteome of neurotypical human and macaque postmortem brains. In Aim 3, we perform integrative identification of functional genomic elements and proteomics in diseased brains and iPSC-derived neural cells. In Aim 4, we integrate results from Aims 1-3, as well as with independent genetic datasets of neuropsychiatric populations, to identify non-coding elements, genes, or molecular pathways that will lead to a better understanding of the underlying pathophysiological mechanisms of neuropsychiatric disorders. Finally, these mechanisms will be functionally characterized in model systems. Data from this proposal will also serve as a critical new resource for members of the community, with which they can intersect their results and draw deeper and more meaningful conclusions, especially as the wealth of genomic data from neuropsychiatric disorders continues to accumulate. ## Key facts - **NIH application ID:** 9896867 - **Project number:** 5U01MH116488-03 - **Recipient organization:** YALE UNIVERSITY - **Principal Investigator:** NENAD SESTAN - **Activity code:** U01 (R01, R21, SBIR, etc.) - **Funding institute:** NIH - **Fiscal year:** 2020 - **Award amount:** $1,345,238 - **Award type:** 5 - **Project period:** 2018-07-06 → 2023-03-31 ## Primary source NIH RePORTER: https://reporter.nih.gov/project-details/9896867 ## Citation > US National Institutes of Health, RePORTER application 9896867, 1/2 Cell Type and Region-Specific Regulatory Networks in Human Brain Development and Disorders (5U01MH116488-03).
